Error P0363 - Misfire - No Fuel Delivery

P0132 - Oxygen Sensor High Voltage (Sensor 1, Bank 1)

When the engine control unit (ECU) records trouble code P0132, it indicates that there is some problem with the oxygen sensor. To be more specific, when the ECU detects that the oxygen sensor voltage exceeds 450 millivolts for more than twenty seconds, the P0132 trouble code is triggered.

The main job of the O2 sensor is to monitor the amount of oxygen in the exhaust gases. This information is necessary to ensure optimal engine performance and minimal contamination. Any problem with the oxygen sensor will disrupt vehicle performance and cause trouble code P0132.

What does P0363 mean?

To detect misfires, the PCM uses data from the crankshaft and camshaft position sensors and also takes into account the number of engine revolutions per minute. If the PCM detects that the camshaft or crankshaft position has changed and is abnormal under current conditions, or that the actual engine speed is not at the required value, it will assume that one of the engine cylinders is misfiring. In this case, the PCM will cut off fuel to that cylinder and store P0363.

Symptoms of malfunction

The main driver symptom of P0363 is the MIL (Malfunction Indicator Light). It is also called Check engine or simply “check light”. They can also appear as:

1. Rough or intermittent engine operation, especially when accelerating.
2. Reduced performance as well as engine power.
3. Other misfire-related codes will likely be stored.
4. The “Check engine” warning light may flash.

Causes of error P0363

The most common cause of the P0363 code is a malfunction of one or more ignition system components. The problem may be worn or damaged spark plugs, ignition coils, and related wires.

Other reasons are:

• Insufficient fuel pressure
• Vacuum leak
• Malfunction in the exhaust gas recirculation system
• Fuel injector malfunction
• Clogged catalytic converter

Code P1301 (P1302, P1303, P1304) Cylinder 1 (2, 3, 4), misfire detected, critical for the converter

Codes P0363, P1301 (P1302, P1303, P1304) are entered if: with the engine running - - the crankshaft rotation unevenness measured by the controller exceeds the threshold; — there is no fault code P0336.

The fault indicator starts flashing immediately after a permanent fault occurs. In order to protect the catalytic converter, the fuel supply to those cylinders in which misfires have been recorded may be turned off. Description of checks

1 Check whether misfires are detected at the time of the request. 2 Check the ignition system. 3 Check the fuel supply system. 4 Perform an intake system check. 5 Perform a compression test. Additional checks If the misfires are intermittent, it is necessary to check: - the reliability of the grounding terminals of the ignition system harness; — mechanical damage to the engine (low compression, damage to pistons, camshaft, valves, etc.); — the intake system for the absence of air leaks (check the intake system after the mass air flow sensor for the absence of air leaks, make sure that the vacuum hoses are connected securely and are not damaged); — malfunction of fuel supply system elements (see map A6); — malfunction of the ignition system elements (see map A3); DPKV fastening;

How does a mechanic diagnose a P0363 code?

The mechanic will first visually inspect and, if necessary, repair or replace all loose, frayed, shorted, damaged or corroded wires, connectors and other electrical components. He will then clear the error codes from the PCM memory and test drive the vehicle to see if P0363 appears again. If the error code appears again, the mechanic will continue to diagnose. It will perform diagnostics until it finds a problem.

Related error codes P1301, P1302, P1303, P1304

Along with error P0363, you can also observe the following error codes P1301, P1302, P1303, P1304 - these codes indicate in which cylinder(s) 1, 2, 3 or 4, respectively, misfire occurred. The automatic system analyzes the speed and uniformity of rotation of the crankshaft and, if anomalies are detected, records the necessary error in the log.

Also, in some situations, the fuel supply to those cylinders in which the problem has arisen is turned off in order to protect the engine and its components from negative effects.

Diagnosis of error P0363 (P1301, P1302, P1303, P1304) and related faults at an authorized dealer:

A diagnostic device is connected to the client's car, the ignition is turned on and the car engine starts. Then you need to go to the “Signal Monitoring” section and try to reproduce the conditions under which the error code appears. If error codes are recorded, proceed to check the compression and valve timing. In most cases, after checking and troubleshooting, the error goes away and the car's operation returns to normal. However, if after the work the errors continue to be recorded, they begin checking the fuel supply system.

If checking the fuel supply system does not reveal any abnormalities, there remains one component that may harbor a misfire problem - the intake system, which must be checked for air leaks.

In cases where all checks were carried out correctly, but did not reveal any deviations in the operation of the system, and errors P0363 (P1301, P1302, P1303, P1304) continue to appear, it is necessary to check the engine for mechanical damage.

What repairs can fix the P0363 code?

After detecting the P0363 code using an OBD-II scanner and checking all electrical components, the mechanic will do the following:

• Inspects and, if necessary, repairs or replaces worn or damaged ignition system components such as spark plugs, ignition coils, distributor cap, fuel filter, and related wires.
• Replace the appropriate spark plug and ignition coil on a cylinder that is working properly to determine which component is faulty.
• Takes oxygen sensor readings to determine if a vacuum leak is present and, if necessary, repairs or replaces a worn or damaged vacuum hose.
• Check and, if necessary, clean the clogged catalytic converter
• Repairs or replaces a faulty fuel injector.

Each time a repair is performed, the mechanic will clear the error code from the PCM memory and retest the system to see if the P0363 Owl code still appears. This will help you find out if the problem is resolved.

On-Board Diagnostic System

The vehicle's ECM has an on-board diagnostic system, which includes a warning light in the instrument cluster that lights up when it detects that the exhaust gas toxicity threshold has been exceeded, and also alerts the driver to the need for repair work.

The on-board diagnostic system includes the following types:

— misfire of the fuel mixture; — control of the control oxygen sensor;

— control of ECM elements;

The on-board diagnostic warning light turns on if the on-board system detects the same fault during several trips or engine starts, as well as when faults are detected in electrical circuits.

The OBD warning light flashes when a misfire in the fuel mixture is detected. This emergency situation leads to failure of the catalytic converter.

Information about malfunctions is entered into the non-volatile memory of the computer; this information is deleted automatically after 40 subsequent tests, as well as using a diagnostic tool.

Misfires in cylinder 4 when cold (coils and spark plugs have nothing to do with it)

Good afternoon Lada vesta sw cross 1.8 MT. misfires in cylinder 4. I’ll outline: I start the engine when it’s cold. It starts up, everything is fine. After probably 2-3 minutes, the engine starts to stall, the check light is on (they took the car to an electrician, they say there is a misfire in cylinder 4). Changed the coils - still the same. Changed the spark plugs - still the same.

If you turn off the engine and start it, the engine stops, but the check light is on. After about 20 minutes of driving, the check light stops lighting. If the car sits overnight, you start it and what I described above happens. Then during the day everything is fine.

How to treat? I looked at the forums. The problem is the same, but there are tons of solutions, including disassembling the engine. But the car is new. It's not even a year. Please don’t throw your slippers too hard, I’m not good at these things. Thank you!

Lada Vesta, misfire adaptation.

Lately I have had to adapt misfires; apparently, when I remove the terminals from the battery, the ECU settings are reset (electronic control unit, or in simple terms - the brains).
Although this was not observed in winter, when I removed the battery for recharging, i.e. I charged the battery, put it back in place and the car drove as before. As soon as the problems with the throttle valve started and the specialists from the official dealer “wired my brains”, so after that I have to make this adjustment. In the second half of May, the car was at the OD for a week, they recognized the problems with the throttle valve as a warranty issue and said that they would change it, but in the end they limited themselves to “brain firmware.” And when I picked up the car and drove off, the car wouldn’t move at all, I pressed on the gas, the instantaneous consumption was more than 30 liters, and it barely accelerated, but after adaptation everything became normal. I had to do it the second time after replacing the antifreeze, because... If I removed the positive terminal from the starter, I also removed the negative terminal from the battery, to avoid a short circuit. After replacing the antifreeze, I also felt that the car was not driving right, but after adaptation everything became normal. The screenshot above describes the entire setup cycle, I’ll add on my own behalf that before making this adaptation, you need to remove both terminals from the battery and wait 5-10 minutes, I myself waited half an hour, and then drive it immediately in second gear. When I left the garage, after replacing the antifreeze, I drove around the city in different gears and felt that the car was not driving as well as before, I drove onto a straight line, made an adjustment in second gear, but it did nothing. But, the next day, after I removed the terminals from the battery and made the adjustments, then the car was configured perfectly.

Here's what to do if the spark plugs were changed 3-4t. km. back (to maintenance) When the problem arose for the first time, they changed the coil in the second cylinder, but after 3 days the problem came out again - they cleaned all the injectors, replaced the fuel filter, but after 3 days the same problem again...

does the CHECK appear on the dashboard?

1) Regarding the temperature sensor, not all trim levels have it. Buy and connect) What is the error number?

2) Regarding the stalling, this is a jamb of the factory firmware, specifically for Grants with automatic transmission. Here is an excerpt from the Za Rulem magazine article “The same Jatco JF414E automatic machine works on the Grant and the mi-DO hatchback. The editorial mi-DO made me suffer: sometimes when braking or even in leisurely walking mode, the engine suddenly stalled. To restart it, it was necessary to put the machine into “parking”, and this can only be done by stopping completely! The reason for the vagaries lay in the fact that initially the engine calibrations were calculated for the version with a manual transmission, but for a car with an automatic transmission they were not the best fit: the mechanical losses of the transmission were not taken into account, which are much higher in hydromechanics. ————-We managed to push through solution to the problem at the factory level: a diagnostic unit was installed in the editorial car, which we drove with for several months. Decryption made it possible to catch errors, and mi-DO received new firmware for the engine control unit. Now this program has gone into series: with its appearance, other unpleasant symptoms of automatic Datsuns have disappeared. The engine speed no longer drops during heavy braking, and the cramps that shook the car when the air conditioning was turned on have disappeared.”

Troubleshooting

If during diagnostics an error 0363 of a VAZ 2114 is noticed, then the reasons for this may be the following:

The first of these problems is quite simple to solve - you should try to refuel with gasoline from other manufacturers, and not the one that is currently used. Despite its apparent simplicity, this method very often helps - after all, as statistics show, more than half of the cases of error 0363 are associated with low-quality fuel.

If an error occurs very often and, as a result, leads to the shutdown of one of the cylinders (but the engine itself and related units are fully operational), you can reflash the engine control unit, removing information about this error from it.

If replacing the fuel does not help and the troubles continue, you should check the air intake system. It is necessary to tighten all fastening clamps, replace the air filter if it is worn out, and also measure the pressure in the ramp (normally it does not exceed 2.8 atmospheres).

The next step in troubleshooting will be diagnosing the ignition system.

So, you will need to check:

In order to check the condition of high-voltage wires, you need to measure their resistance with a tester. Normally it should not be more than 10 kOhm. If the measurements show greater resistance, then the wires are faulty and should be replaced (this should be done even if a regular “continuity test” shows the presence of a working circuit).
