Trouble P0342 - Camshaft Position Sensor “A” Bank 1

The crankshaft sensor error code P0336 is called “Crankshaft Position Sensor “A” Circuit Out of Range.” The cause of the formation may be a damaged crankshaft, displacement of the reference mark, partial failure of the crankshaft position sensor (abbreviated DPKV) or damage to its wiring. To perform repairs, one of several actions is usually performed - replacing the DPKV, the gear on the shaft, or insulating the HF sensor wires.

Causes of error P0346

The most common cause of P0346 is an engine oil or transmission fluid leak that has damaged the camshaft position sensor or electrical components in the system.

Other reasons are:

Camshaft position sensor malfunction
Malfunction of the crankshaft position sensor
Short circuit or broken camshaft position sensor wires
Poor electrical connection in the camshaft position sensor circuit
Starter motor malfunction
There is a malfunction in the engine starting system
Low or completely discharged battery
In rare cases, PCM malfunction

External signs

When P0336 crankshaft sensor circuit error is formed in the memory of the electronic engine control unit (abbreviated as ECU), there are a number of external signs that appear on the behavior of the car, if they occur, an additional check should be performed with a scanner for diagnostics. It is worth noting that the symptoms listed below may indicate the presence of other problems, not just crankshaft sensor errors. So, p0336 manifests itself as follows:

The Check Engine light on the dashboard activates.
Misfire occurs in one or more engine cylinders. That is, the engine begins to “trouble”, which is clearly audible by the sound.
Loss of dynamic characteristics of the car, the engine accelerates poorly (increases speed). There is also a loss of power, which is expressed in the fact that the car “does not pull,” especially when driving uphill or under a load.
Problems with starting the engine, up to complete inability to start the engine.
Engine vibration during operation. In this case, not only vibrations and the accompanying unpleasant clanging sounds often occur.
The engine stalls, and this can happen not only at low, but also at medium and high speeds, including when the car is moving.
Fuel consumption increases, and in all engine operating modes.
When the engine is running at idle speed, their value may be unstable (that is, the speed “floats”).

According to statistics, crankshaft error p0336 most often occurs on Gazelle, VAZ, Kia, Honda, Chevrolet, and Ford cars. But owners of other cars are not insured against it either. Moreover, the decoding of diagnostic code p0336 may differ and sound like: “DPKV error A missing one tooth”, “Crankshaft Position Sensor A Circuit Range/Performance”, “Incorrect indicator / crankshaft position sensor A not adjusted.”

How does a mechanic diagnose a P0346 code?

First, the mechanic reads all stored error codes using an OBD-II scanner. He will then visually inspect and, if necessary, repair or replace any shorted, loose, damaged or corroded wires and connectors related to the camshaft position sensor. The mechanic will also perform a thorough check for engine oil and transmission fluid leaks and, if necessary, repair any leaks present.

The mechanic will then clear the error codes from the PCM memory and retest the system to see if P0346 appears again. If the error code appears again, the mechanic will continue to diagnose. It will perform diagnostics until it finds a problem.

Additional comments for troubleshooting P0342

The camshaft position sensor is an integral part of the system that allows the vehicle to operate reliably, smoothly and quietly. If the sensor does not operate properly, symptoms will occur indicating a problem. If the problem is not solved for a long time, it can lead to more serious problems. Therefore, if a P0342 error is detected, it is recommended that you contact a qualified technician as soon as possible to diagnose and resolve the error.

It should also be noted that if this error code is stored in the PCM and the Check Engine Light illuminates, the vehicle will most likely fail an emissions test.

What repairs can fix the P0346 code?

To resolve code P0346 you may need to:

Detecting and repairing engine oil or transmission fluid leaks
Repair or replacement of the camshaft position sensor
Repair or replacement of the crankshaft position sensor
Repairing or replacing broken, shorted, or damaged camshaft position sensor wires
Repair or replacement of a faulty starter motor
Charging or replacing the battery
Repair or replace damaged or corroded electrical connectors.
In rare cases, repair or replacement of the PCM

How to Troubleshoot or Reset Trouble Code P0342

Some suggested steps to troubleshoot and fix error code P0342:

Inspect the wiring, looking for corrosion, poor connections or frayed insulation.
Check the connector on the camshaft sensor. Look for corrosion and defects in the connector. Apply dielectric grease to the connection.
Replace the camshaft position sensor.
Test the battery condition. Low battery power may cause a code to set.
Check the starter for excessive pull, indicating weak recoil.

Often replacing the sensor will correct the P0342 code, but not necessarily. Therefore, it is important to check all points.

Code P1336 Monitoring the control of the throttle valve drive, mismatch of signals from sensors “A” / “B” of the throttle position

Code P1336 is entered if: - the ignition is on; — the sum of the signals TPS A and TPS B differs from the reference voltage of 5 V by more than 0.3 V for 0.5 s.

The malfunction indicator lights up 5 s after the fault code appears. Description of checks

1 Using a scan tool, check whether code P1336 is active at the time of diagnosis. 2 The check is carried out in accordance with the map for code P2135. Diagnostic information Diagnostic tool in “1 Parameters” mode; 6 Add. Options; 3 ADC inputs” shows the signals of TPS A (UDKP1) and TPS B (UDKP2) in volts. When the throttle valve is opened, the TPS A signal increases, the TPS B signal decreases. With the throttle valve fully closed, the TPS A signal should be in the range of 0.3...0.6 V, the TPS B signal should be in the range of 4.4...4.7 V. The controller recalculates the voltage signals of TPS A and TPS B into the percentage of throttle opening flaps. The diagnostic tool is in “1 Parameters” mode; 1 General view" displays the percentage of throttle valve opening WDKBA, which is calculated as the arithmetic average of the signals TPS A (%) and TPS B (%). 0% corresponds to a fully closed throttle. 100% corresponds to the maximum throttle opening per lever. The signals TPS A and TPS B are mismatched if the following condition is met: |5 V – (UDKP1 + UDKP2)| > 0.3 V If a mismatch between the TPS A and TPS B signals is detected, the engine control system will operate in emergency mode until the end of the current trip: de-energizing the electric throttle drive and limiting engine speed (2500 rpm). If the EDM or ECM is replaced, or the controller is reset using the diagnostic tool (mode “5 Additional tests; 1 ECM reset with initialization”), it is necessary to perform the throttle valve zero adaptation procedure. To do this, with the car standing, you need to turn on the ignition, wait 30 seconds, turn off the ignition, and wait until the main relay turns off. Adaptation will be interrupted if: — the engine is cranking; — the car is moving; — the accelerator pedal is pressed; — engine temperature below 5 °C or above 100 °C; — ambient air temperature below 5 °C. If the electric throttle actuator is de-energized, the throttle valve is held in the Limp home position (6-7%) using direct and return springs.

DESIGN FEATURES AND OPERATING PRINCIPLE

The VAZ 2114 FAZ sensor is an integrated device, the main function of which is to receive information about the current operating cycle of the power unit and transmit it to the ECU via pulse signals.

Structurally, the DF consists of two parts - a sensitive element and a pulse signal converter, which in turn consists of an operational amplifier, a bridge circuit and an open collector type output stage.

The DF sensitive element operates according to the Hall principle; it is a microcircuit that responds to fluctuations in the magnetic field, which gains the ability to transmit an electrical signal only when there is a magnetically conductive material next to it, which is the steel head of the valve.

The location of the VAZ 2114 camshaft position sensor is as follows: it is located on the end of the cylinder block, not far from the air filter.

Location of DF

There is a lot of discussion on the Internet about which phase sensor is best to buy from which manufacturer. We recommend giving preference to devices from the German company Bosch. It is she who has the license to manufacture sensors operating on the Hall principle, so, in essence, you get a reliable and durable device produced by the direct owner of the technology by which it is made.

What does P0336 mean?

Trouble code P0336 indicates that the engine control module (ECM) has detected a malfunction in the crankshaft position sensor A circuit.

The crankshaft position sensor records the crankshaft speed, controls the operation of the engine valves (in particular, the operation of the pistons), as well as the engine itself. The ECM uses information received from the crankshaft position sensor to control fuel injection and ignition timing. The crankshaft position sensor and ECM are required to operate properly to operate your vehicle safely.

The crankshaft position sensor consists of a rotating disc and a stationary sensor. Most crankshaft position sensors have a voltage wire, a ground wire, and a signal wire that allows the ECM to receive a revolutions per minute (RPM) signal.

Using the above information, as well as data received from the camshaft position sensor, the ECM controls the fuel injection process and also regulates ignition timing. If the ECM does not receive or receives an erroneous signal from the crankshaft position sensor, the P0336 .
