Trouble P0335 - Crankshaft Position Sensor “A” - Circuit Malfunction


Code P0335 – crankshaft position sensor error A. Depending on the controller, diagnostic tool or program, other options for deciphering the code are possible, for example, “HF synchronization sensor error” or “crankshaft position CKP sensor circuit malfunction”. DTC P0335 is universal to all makes and models of vehicle and indicates no signal or its deviation from the norm.

The behavior of the car when this error appears may vary - from fluctuations in speed and uneven operation of the engine to its stopping and the impossibility of restarting.

You can learn more about when crankshaft sensor error P0335 occurs, its accompanying symptoms, and how to diagnose faults in this article.

What are the symptoms of P0335?

Symptoms of the P0335 may vary depending on the make and model of your vehicle. Typically, when this error appears, the Check Engine light on the dashboard lights up, but it should be noted that in some cars this light may not light up immediately, but only after the error has been detected multiple times. The main symptoms of a P0335 include loss of engine power, engine stalling, trouble starting the engine, and decreased fuel efficiency.

Guys, the problem is this... I washed my wife’s car 2112 today and washed the engine! After I blew everything out thoroughly, I started it without any problems! I went to change the springs on it. I changed it myself near the garage for about 2 hours - I collected it and started getting ready to pick it up for work. I start it up and it starts without problems. I went to the other end of the city - no problems. I picked it up and on the way back we stopped many times, turned it off, went shopping and started it up again without any problems. I came home and installed it - everything is fine! and after 4 hours I start it up and it turns stupidly but doesn’t start... the on-board engine gives an error 0335 HF SYNCHRONIZATION SENSOR ERROR - what is this anyway? where should I go to look? I removed all the chips from the sensors - everything is dry... everything is put back in place - nothing is torn off anywhere. but it won't start...

How does a mechanic diagnose a P0335 code?

First, the mechanic reads all the stored data and error codes using an OBD-II scanner. He will then clear the error codes from the PCM and test drive the vehicle to see if P0335 again. If the error code appears again, the mechanic will visually inspect the crankshaft position sensor as well as the associated wires.

The mechanic will then check the crankshaft position sensor readings as well as the RPM signal using a scanner. If the readings are within the specified range, the mechanic will check the electrical wires. If no problem is found, the mechanic will check the PCM according to the manufacturer's procedure.

Diagnostics and testing methods for the crankshaft position sensor

The essence of diagnostics when error P0335 appears comes down to checking the functionality of the sensor, as well as visual inspection of the parts involved in the formation and transmission of the signal for damage.

Troubleshooting the DPKV and the procedure for diagnosing error P0335:

  1. We visually check the sensor itself and the wiring, paying special attention to the condition of the insulation, contacts and connectors. We clean the surface of the sensor from dirt, dust, oil, and metal shavings.
  2. Inspect the ring gear of the crankshaft pulley. We make sure that there are no backlashes, the integrity of the teeth and runouts.
  3. We check the condition and correct installation of the timing chain or belt by the location of the marks and the condition of the tensioner.

If there are no visual reasons for the error, we proceed to checking the crankshaft position sensor itself, having previously dismantled it. In most cases, it is secured with one 10mm bolt.

Inductive sensors and Hall effect sensors are used as DPKV. Two-wire inductive sensors consist of a permanent magnet and a winding, at the terminals of which, when the next tooth of the crown passes next to the sensitive element, an alternating voltage is formed, which is converted into a step form in the ECU.

The operating principle of a three-wire Hall effect sensor is based on a change in the reference voltage as a result of the deflection of the magnetic field by a toothed disk as it rotates. In this case, a step-shaped digital signal is immediately generated.

You can reliably check the serviceability of the DPKV only by taking an oscillogram of the signal on a car with the engine running and comparing it with the reference one. However, due to the high cost of the equipment and the lack of data on the waveform for a specific model, even service station mechanics use alternative methods for checking the performance of HF sensors.

Checking inductive DPKV

How to check the crankshaft position sensor using improvised means: video

Method number 1 . To check, you will need two insulated wires, a low-power lamp (from the interior light or license plate) and a steel object (key, screwdriver, nail). The good thing about this method is that it allows you to quickly check the DPKV on the road.

  1. Connect the wires to the sensor terminals.
  2. Press the opposite ends to the lamp contacts.
  3. Bring the metal object close to the sensor until it makes contact and move away from it.
  4. Flashes of the lamp indicate that the sensor is generating a voltage signal.

Method number 2 . To check, you will need a multimeter and a steel object.

Checking DPKV with a multimeter: video

  1. Set the multimeter to DC voltage measurement mode in the 200 mV range.
  2. Connect the probes to the sensor leads.
  3. Bring the steel object towards the sensor and move it away from it.
  4. When an object approaches the multimeter, the voltage should be recorded in the range of 0.1–1 V.

Method number 3 . You will need a multimeter to check.

  1. Set the multimeter to ohmmeter mode, 2kOhm range.
  2. Measure the sensor resistance.
  3. If it is in the range of 550–750 Ohms, the sensor is working. Lower values ​​indicate a short, and higher values ​​indicate an open circuit.

Additional comments for troubleshooting P0335

The crankshaft position sensor is used to monitor the crankshaft speed. The vehicle's PCM uses data from the crankshaft position sensor and camshaft position sensor to regulate ignition timing and fuel distribution.

Properly diagnosing the P0335 requires an advanced scan tool that can not only read stored trouble codes, but also allow you to view readings from various sensors in real time.

Possible reasons for the check function to light up

The “CHECK” signal is located in the very center of the instrument cluster, where the driver can quickly pay attention to it.

This function is responsible for the operation of the engine and if it signals, then there may be problems in the operation of this particular unit. Of course, this is scary for any motorist, because repairing the power unit is complex and expensive. But don’t immediately get scared and panic, the reason may be petty.

So, let’s look at what are the reasons why the “CHECK” function on the Lada Grant came on:

  • If the indicator lights up when you start the engine, then don’t worry, everything works.
  • If the “CHECK” lights up and signals for a long time, then, first of all, it is necessary to make a diagnosis, and only then worry.
  • If “CHECK” is heard while driving, this may mean that there is insufficient oil level in the engine ( p0523 - error when the oil pressure sensor is faulty ).
  • The “CHECK” function is on - it’s worth checking the engine for signs of depressurization or oil leakage.
  • If the above reasons do not work, but the “CHECK” is lit, then this may be a signal that the spark plug has failed or low-quality fuel has been filled.

When the “CHECK” function lights up, it indicates that something is wrong with the engine and it is worth carrying out diagnostics before taking other actions.

Elimination methods

Let's consider some options for eliminating the causes of the “CHECK” function fire on the Lada Grant:

  1. Bad fuel. The elimination method is quite simple - drain the low-quality fuel and fill in new one. Let the engine run a little and turn it off. If everything is normal, then upon startup, the signal will disappear. AvtoVAZ recommends refueling with 95 gasoline, but it often causes errors and complaints about its quality. What kind of gasoline do you fill up with, 92 or 95?
  2. Spark plugs and high-voltage wires. Unscrew all spark plugs and check the gaps and the presence of a spark. Replace faulty spark plugs and wires.

The faults that you can fix yourself are indicated, but if nothing works, you should contact a car service.

Underwater rocks

If the “CHECK” light comes on on the Lada Grant, then do not panic. Often on cars the signal is supplied from a common ECU, which, like any computer, can malfunction. This may be caused by a short circuit or replacement of electrical circuit components. Therefore, errors occur in the electronic control unit, which can serve as a “CHECK” signal.

The ECU in Grant is not located very well, and if your check light came on during or after rain, then water could have gotten into it due to design features.

This problem can be treated quite simply. The ECU itself needs to be connected to a software laptop and errors in the system should be corrected or outdated firmware changed. It is best to entrust this operation to specialists who know how it is done.

Resetting an error without using an adapter (collective farm method)

If you are sure that the check engine light is “temporary”, that is, the quality of gasoline is poor, or the spark plug was faulty, which has already been replaced with a working one, then the check engine light can be reset manually without using an adapter; there are two ways.

  1. To do this, disconnect the terminal for five minutes , the memory in the electronic engine control unit (ECU) will be reset, and the on-board computer readings will also be reset.
  2. There is a second way, you just need to remove the cigarette lighter fuse ; Grant's design engineers installed an immobilizer on it.
