Trouble P0341 - Camshaft Position Sensor “A” Bank 1 - Range/Performance

How does a mechanic diagnose a P0341 code?

When diagnosing this error code, a mechanic will do the following:

• Reads all stored data and error codes using an OBD-II scanner.
• Clear error codes from the ECM and test drive the vehicle to see if P0341 appears again.
• Check the camshaft position sensor wires and connectors for looseness or damage.
• Check the resistance and voltage of the camshaft position sensor.
• Check the camshaft position sensor connector for corrosion.
• Check the camshaft position sensor gear for wear and damage.

Where is the unit located?

The sensor is located on the engine in two versions: on an 8-valve engine it is installed on the cylinder head, and on a 16-valve engine it is installed on the side of the drive camshaft in the area of ​​the generator. It can be easily found and dismantled without visiting a car dealership, although the second option will require more effort and skills.

Error codes indicating a car malfunction by computer using the OBDII protocol

When a car breaks down, the on-board computer produces a certain number that needs to be deciphered. Digital codes can be divided into groups in different car systems.

Fuel supply system

DPRV error. Malfunction of the crankshaft position sensor (CPS)

During engine operation, the ECU monitors the synchronization between the DPRV and DPCV. Therefore, if the DPKV malfunctions, the engine control unit can easily throw out an error on the DPKV. This happens all the time. Therefore, be sure to check the serviceability of the DPKV circuit if there is an error according to the DPKV.

I showed how to do this in this video.

Especially if these problems began after washing the engine or driving through deep puddles. Treat the DPKV connector with special means

And if you have a car with an MR-140 control unit, for example, a Chevrolet Lacetti 1.8, then it may be worth carrying out the DPKV training procedure

How to Troubleshoot or Reset Trouble Code P0346

Some suggested steps to troubleshoot and fix error code P0346:

1. Check that the wiring is not routed too close to the secondary ignition components (coils, spark plug wires, etc.).
2. Visually inspect the sensor wiring for burning marks, discoloration indicating melting or wear.
3. Inspect the camshaft sensor for damage.
4. Carefully inspect the relay wheel through the camshaft sensor hole (if possible) for missing teeth or damage.
5. If the gearbox is not visible from the outside of the engine, then visual inspection can only be done by removing the camshaft or intake manifold (depending on engine design).
6. When all the steps have been completed and the error has not gone away, replace the sensor. In most cases this will solve the problem.

Often replacing the sensor will correct the P0346 code, but not necessarily. Therefore, it is important to check all points.

Diagnosis and problem solving

The camshaft position sensor is an electronic device used in the engine to record the speed of the camshaft. This information is used by the engine control module (ECM) to control ignition and fuel injection.

The position sensor detects the position of the camshaft to identify a specific cylinder and the position of the piston. A sensor system consists of a rotating part, usually a disk, and a static part, the actual sensor.

Examples of vehicles with P0341

• An Acura service bulletin (TSB) describes an issue where a stuck or dirty VTC (variable valve timing) control solenoid valve can cause trouble code P0341. The bulletin recommends updating the ECU software and replacing the VTC solenoid valve if necessary.
• The service bulletin for 2003 Jaguar V6 models mentions checking the spark plug resistance and replacing the spark plug along with the coil if the spark plug resistance is too low.
• A technical service bulletin for late 90's Saturn vehicles describes a problem where improper resistance in the ignition wires can cause a P0341 code.
• For a 2010 Chrysler pickup equipped with a Cummins diesel engine, in case of P0341 it is recommended to reflash the ECU.
• In some 2003-2010 Honda Accord, Civic, CR-V and Element 4-cylinder engines, a stretched timing chain causes the Check Engine Light (MIL) to come on with code P0341.

Technical description and interpretation of error P0346

This diagnostic trouble code (DTC) is a generic powertrain code. The P0346 code is considered a common code because it applies to all makes and models of vehicles. Although the specific repair steps may vary slightly depending on the model.

The camshaft position sensor (CPS) sends a special signal to the engine control module (ECU) for top dead center on the compression stroke. As well as signals indicating the position of the cam sensor.

This is achieved by a relay carrier wheel attached to the camshaft, which passes by the cam sensor. Whenever the signal to the ECU is not within the desired performance range, this error code appears.

This code may also be set due to long scrolling periods.

Symptoms of malfunction

The main driver symptom of P0341 is the MIL (Malfunction Indicator Light). It is also called Check engine or simply “check light”.

They can also appear as:

1. Poor fuel economy (if the engine is running).
2. Possible absence or problems with starting.

The vehicle will most likely run with this trouble code as it is often intermittent (flickering). And also because the ECU can often operate the car in “sluggish” or emergency mode. Even if there is a problem with the cam sensor signal.

What are the errors that determine the malfunction of this mechanism?

Error code - 0340

A fairly common phenomenon occurs when the “meat grinder” on the dashboard (check engine) lights up. This process appears like this: when starting the engine, the starter works for several seconds, and then phase sensor error 0340 is displayed. The thing is that when starting the car, the electronic unit The engine control waits for a certain signal from the phase sensor. If it is absent, the control unit does not send an impulse to the ignition system and fuel supply system. Consequently, the engine does not start, and the engine control lamp comes on, indicating “error 0340” on the VAZ 2114. You can diagnose the breakdown using the car’s on-board computer, or contact a specialized service center.

Check engine error on VAZ 2114

Symptoms of this problem:

1. Increased fuel consumption.
2. Difficulty starting the engine.
3. Perceptible noise when turning on the ignition key.

Error code - 0343

Indicates a high level of the regulator pulse; this error in the VAZ 2114 phase sensor is less common than the first, and it is directly related to a malfunction of the device itself. The problem is solved by completely replacing the unit; it does not require diagnostics or visits to specialized salons. Error 0343 may be associated with simple oxidation of the wires on the mechanism, which need to be cleaned and their integrity checked.

Attention: there should be 12V at the mechanism terminal and at pin A, and 0V at the rest.

An error in the phase sensor can be caused by a malfunction of the crankshaft position sensor, it is also possible that the timing belt has slipped onto a tooth, the key of the generator belt pulley has been turned out, the crankshaft gear has become loose, wear has occurred on the upper and lower gears. As you can see, there can be many clues; the main thing is to correctly diagnose and effectively fix the problem.

Signs of a malfunction of the phase sensor on the VAZ 2114 associated with this error may be:

• deterioration in speed gain when accelerating a car;
• problems in engine operation, when starting the unit;
• The starter spins for 4 seconds when starting and the check light comes on;
• diagnostic mode failure;
• exhaust gases become transparent, the level of carbon dioxide emissions increases.

Attention: the “Check Engine” control signal (a light on the instrument panel that indicates a malfunction in the engine control system), with a working engine, should go out 0.6 seconds after starting. This is quite enough for the diagnostic system to state that everything is in order.

If the light continues to light, then there is a malfunction, and the error on the VAZ 2114 is an exact confirmation of this. It can be identified using a professional scanner at a service station or “with your own efforts.” We are talking about a superficial diagnosis of the cause, which can give an idea of ​​​​the approximate identification of a product malfunction. What to do next is up to the car owner to decide; you can replace the sensor with a new one and get rid of all “instrument errors”, and you can also do a general cleaning of the mechanism wires, completely rinse the entire sensor in a special liquid.

Attention: there is such a situation - I changed the sensor, and after a few hours the light comes on again. This problem can arise when refueling with low-quality fuel, or the mechanism is incorrectly installed and requires professional intervention from specialists! You can also get caught in a marriage, and this happens. It is necessary to do initialization after changing the sensor in order to avoid such a problem.

If the car is on the road and error 0343 or 0340 appears, then the following option can be used as a temporary solution to “treat the problem”: rotate the sensor a few degrees around its axis, and then securely fasten it again.

This method will help regulate the fuel supply in the correct mode and reduce fuel consumption when driving the car.

If symptoms of a malfunction of the camshaft position sensor are detected, it is necessary to visually check the mechanism. There may be a problem with one of the following:

• external damage;
• condensation has formed or deposits have formed on the contacts;
• The integrity of the electrical wiring near the unit has been damaged.

If everything is in order, then it is necessary to dismantle the device. You can make the replacement yourself, without visiting a service center.

The cost of a new camshaft sensor for the VAZ family is about 10 (600 rubles) dollars.

Have a good trip and pleasant fellow travelers!
