Not right. Contact C goes to connection point S12, and this is ground. If the wiring is intact, but error p1135 does not go away, then the heater itself in the oxygen sensor is faulty. And you need to measure AD - approximately 0.45 V and BC battery power.

A D = 2.82 BC = 12.12 Battery = 12.24

As I understand it, A-18 ECU contact B- 63.44 ECU contact C- ground? (Put it directly on the body?) D- 48 ECU contact

A- 18 contact of the ECU, D- 48 contact of the ECU, Read the measurements from the diagnostic scanner, because A reference voltage is applied to A, which you measure when you throw the second probe at C (ground). B - connection point S2 which is recorded from the main relay of the ECU +12 volts, C - connection point S12 is connected to the vehicle ground. When you measure AD, you get a voltage drop across the ECU measuring element, which is why the tester shows a lower voltage. If there is 12 volts on the aircraft, but error 1135 does not go away, then the heating element of the sensor itself is faulty. If the sensor itself is working, it should produce a sinusoid on the scanner, but only when it warms up to operating temperature from the exhaust gases.

Of course, this is not a happy situation for car owners if the check engine lights up on the car’s dashboard. In this case, you have to contact a specialized service station, where they will diagnose the engine, or if you have an on-board computer installed, identify the breakdown yourself by deciphering the VAZ error codes.

Common Problems Causing Code P0135 on Different Vehicles

In some Acura, Honda, Lexus and Toyota , this code is known to be caused by a faulty sensor heater element. A faulty oxygen sensor (bank 1, sensor 1) can be confirmed by measuring the resistance of the sensor's heating element.

The resistance should be low, usually between 0.9 and 10 ohms, depending on the vehicle. Specifications for different vehicles can be found in the owner's manual. Replacing the sensor often solves the problem.

On some Chrysler , the P0135 code may be caused by an improperly replaced sensor. Different types of sensors may be used on the same vehicle, depending on the vehicle's production date. It is important to check the correct sensor part number using the vehicle's VIN number.

Corrosion on the DC connector is known to cause this code to appear in many vehicles. The connector should be inspected for corrosion. If present, you need to clean the terminals or replace the connector. For example, the Chrysler service bulletin for Dodge Ram recommends repairing the sensor wiring harness using a special repair kit.

In some older Mazda , corrosion of the wiring inside the fuse box can cause code P0135. This can be confirmed by checking the 12V voltage and ground at the sensor.

Troubleshooting

Note! If you are unsure of your own abilities, the motorist is strongly recommended to seek help from a specialized workshop or a qualified technician.

If you have the necessary equipment, you can determine whether 8 or 16 valves are broken in a Lada Priora car yourself. Due to the simple design of the machine, repairs do not require the user to have in-depth knowledge of mechanics, electronics or other sciences.

Hello. I got error 1570 on BC - “immobilizer, no positive response or open circuit.” It appears when you turn the ignition key in the form of a beeping buzzer (the car with the key on the dashboard does not blink or light up), and it does not stop for some time after starting the engine. Resetting the error does not help. How to defeat her?

How to diagnose a VAZ-2114

How to use the self-diagnosis function without taking into account the on-board computer?

Press the car daily mileage reset button.
At the same time, turn on the ignition with the key in the first position.
Remove your finger from the key responsible for operating the odometer - the arrows should start moving.
Press the key again and release - this simple method will fix the firmware version.
All that remains is to press the button a third time, then release it; If there is a malfunction, an error code will appear on the screen.

Example of step-by-step diagnosis of code P0135

The check engine light came on on a Honda. Trouble code P0135.

Clearing the fault code using the OBD2 diagnostic scanner. According to this vehicle's owner's manual, the first step is to clear the code and check to see if it returns. This is necessary to see if the code is intermittent or constant.

We erased the code and started the car. The Check Engine immediately returns with the same code.

The next step, according to the instructions for this Honda, is to turn the ignition to the LOCK position and check fuse No. 14 FI SUB (15 A). The fuse location is indicated on the back of the fuse box cover.

Check to see if the fuse is blown. We checked the FI SUB fuse - everything is fine. The next step according to the manual is to test the PGM FI slave relay. We tested the relay - it also worked.

The next step in the diagnostic process is to disconnect the oxygen sensor connector and measure the resistance of its heating element.

The multimeter shows 235 kOhm (kiloohm). According to the repair manual, the resistance should be between 2.5 and 4 ohms. This means that the DC heating element has failed and the sensor must be replaced.

We purchased a new front oxygen sensor and tested the resistance of the heating element for comparison.

As you can see, its resistance is 3.4 ohms. We installed a new sensor and cleared the code. The check engine has not returned, this car is fixed.

How to decipher error codes

If you have ever seen how a VAZ-2114 is diagnosed using special equipment in a service station, you probably noticed that the error code has 4 digits. In our case, during self-diagnosis, the code includes only 2 numeric characters. In general, the codes mean the following:

if the number 1 appears, it means the microprocessor is malfunctioning;
2 – the operation of the sensor circuit indicating the fuel level in the tank leaves much to be desired;
4 – there is too high voltage in the electrical circuit;
8 – the voltage, on the contrary, is too low, it is not enough for the VAZ-2114 to operate properly;
13 – there is no signal from the indicator of available oxygen;
14 – high signal value of the coolant temperature indicator, filled in for efficient operation of the car’s cooling system;
15 – this signal, on the contrary, is too low;
16 – voltage units in the on-board network are off scale;
17 – low voltage values of the on-board network;
19 – the signal from the locking component regarding the position of the crankshaft is received incorrectly or untimely;
24 – the sensor that records the vehicle speed is faulty;
41 – the phase sensor signal is received incorrectly;
51 – there are problems in the functioning of the operational product responsible for memorization;
53 – it’s time to repair the CO potentiometer;
61 – lambda probe does not work.

Why does runtime error 1135 occur?

“Nero Error 1135” can most often occur when loading Nero. We can determine that errors during the execution of error 1135 come from:

Error 1135 Crash - The error number will cause the computer system to lock up, preventing you from using the program. This occurs when Nero does not respond to input properly or does not know what output is required in return.

Memory Leak “Nero Error 1135” – When Nero memory leaks, it can cause your device to run slowly due to lack of system resources. There are some potential issues that could be causing problems at runtime, with incorrect coding leading to infinite loops.

Error 1135 Logic Error - Nero's logic error occurs when it produces incorrect output despite the user providing correct input. It materializes when Nero's source code is faulty due to a faulty design.

Such Nero Error 1135 problems are usually caused by corruption of a Nero-related file, or in some cases, its accidental or intentional deletion. Typically, any problem with a Nero file can be resolved by replacing the file with a new copy. If Nero Error 1135 occurred as a result of uninstalling it due to a malware infection, we recommend running a registry scan to clean up any invalid file path references created by the malware.

What does code P0507 mean?

Trouble code P0507 is triggered when the engine idle speed is higher than expected. All modern engines have a desired idle speed - usually between 600-1000 rpm.

The control unit uses position sensing and throttle adjustment to achieve these speeds. If the idle speed exceeds these set values and the maximum adjustment zone, the control unit will generate this error code.

Code P0507 is a common code for vehicles equipped with Electronic Throttle (E-Gas). Newer vehicles usually use E-gas.

The throttle valve is only called electronic. It replaces the old throttle body with a cable between the gas pedal and the throttle body.

The electronic throttle body uses sensors on the gas pedal and an electric motor in the throttle body to provide the desired acceleration. But this does not mean that this error code must necessarily be related to a faulty throttle valve. It can also have many other causes.

How is self-diagnosis performed?

We have sorted out the main errors on the Priora, now it’s worth finding out how self-diagnosis is performed. The VAZ 2170 with 16 valves has a special controller with which diagnostics are performed. If you have an on-board computer installed, then diagnostics are performed on it. There is also special equipment that allows for a more in-depth check of Priora 16 class systems.

Since most Priora 16 cars already have an on-board computer, we will consider the option without the use of special devices. Diagnostics begins with activation of the test mode. The work proceeds according to the following scheme:
