P0336 Code Symptoms and Cause | How to Fix P0336 Code?

The crankshaft position (CKP) sensor uses to calculate the position and speed of the crankshaft. Your vehicle PCM uses this data to regulate ignition timing and fuel delivery. When the powertrain control module detects a problem with the CKP sensor signal, it will trigger code P0336. This article describes the symptoms and causes of the P0336 code.

P0336 Code Definition

P0340 stands for “Crankshaft Position Sensor “A” Circuit Range/Performance.”

What does the Code P0336 Mean?

The P0336 code is triggered when the powertrain control module (PCM) detects an irregular/insufficient signal coming from the crankshaft position sensor.

P0336 code

The DTC P0336 can be generated due to mechanical or electrical issues within your car. Mainly, the electrical issue is a faulty sensor, and the mechanical issue is a bad reluctor ring that sends the crankshaft position readings to the crankshaft position sensor.

Function of Crankshaft Position Sensor

The main function of the CKP sensor is to monitor the engine valves with the proper working of pistons, record the rotation speed of the crankshaft, and monitor the engine’s performance. The powertrain control module takes data from the crankshaft position sensor to regulate the ignition timings and the fuel injection process.

The efficient operation of the PCM and the CKP sensor provides well-controlled emission performance and the power out of your car. This linked working mechanism enables your car to be reliable and give maximum driveability.

The CKP sensor consists of a stationary sensor and a reluctor (rotating disc). Maximum CKP sensors have a ground wire sensor, a signal wire sensor, and a voltage wire sensor. All of these three sensors collaborate to deliver the RPM signals to the PCM of your vehicle.

The information from the crankshaft and camshaft position sensors assists the PCM in determining the ignition timing and fuel injection adjustments. But if the PCM fails to receive the proper signals from the CKP sensor, it will not be able to make adjustments, and as a result, it triggers the trouble code P0336.

The damaged CKP sensor should be replaced immediately. Moreover, if it stays in your car for some time, it may cause damage to some other engine parts. It is always recommended to use original equipment manufacturer (OEM) parts while replacing the CKP sensor.

P0336 Code Causes

The following are the most common causes of the P0336 error code:

  • Wires and circuitry have either burnt out or shorted out
  • The teeth of the reluctor wheel have worn down, broken, or damaged
  • Bad crankshaft position sensor
  • A rusted or damaged crankshaft position sensor connector
  • Crankshaft reluctor ring breakage
  • Powertrain control module failure (PCM)
  • Camshaft position sensor failure
  • The wiring for the crankshaft sensor is incorrectly positioned near the high voltage spark plug connections
  • The crankshaft position sensor circuit has open wires
  • Engine misfiring
  • Crankshaft reluctor ring that is loose or incorrectly placed

Symptoms of P0336 Code

  • Erratic idle
  • Check engine light illumination
  • Random or intermittent engine misfire
  • Poor fuel economy
  • Difficulty starting
  • Car may hesitate upon acceleration
  • Engine vibration
  • Intermittent stalling

How to Diagnose the P0336 Code?

You must have the following tools to diagnose the P0336 code:

  • Auto Repair Manual
  • Basic Hand Tools
  • Diagnostic OBD Scan Tool
  • Multimeter
  • Electrical Contact Cleaner

Follow the below-given steps to diagnose the P0336 trouble code:

  • Connect the OBD2 scanner and look for any additional codes. Follow the below-given procedure if you discover any trouble code.
  • Examine the CKP sensor visually for evident damage.
  • Evaluate the reluctor wheel and find any damage. Remember that it should be tightly fitted to the crankshaft.
  • Check for any signs of burns, shorts, or breaks in the wires.
  • Examine the insulation surrounding the crankshaft harness for any signs of damage.
  • Look for cracks, rust, or a loose connection in the connector.
  • Make sure that the CKP sensor wiring is not positioned too close to a high-voltage spark plug cable.
  • Clear all trouble codes, then run a test to check whether any of them come back.
  • While starting your car, examine the RPM reading with the help of a scanner.
  • Use a scanner to verify the CKP sensor signal in the absence of an RPM reading.
  • With the help of the Volt–Ohm meter, measure the resistance of the CKP sensor and the CKP sensor wiring. The manufacturer provides the resistance specifications.
  • Examine the camshaft position sensor with the wiring. The camshaft and the crankshaft sensors both work together, so sometimes, the issue with the camshaft and its wiring badly affects the readings and functions of the CKP sensor.
  • Inspect the reluctor ring on the crankshaft after removing the defective CKP sensor. Check that the engine is fully operational by spinning it all the way around.

Common P0336 diagnosis mistakes

  1. Crankshaft position sensor replacement without reluctor ring examination.
  2. Because the CKP sensor and CMP sensor work together, it is a frequent mistake to replace the CKP sensor when the camshaft position sensor is the real culprit.
  3. Before changing the CKP sensor, it’s essential to figure out the chance that the engine is misfiring or that there is a wiring problem.

What repairs can fix the P0336 code?

  • If necessary, fix any engine misfires.
  • Change the damaged CKP sensor.
  • A damaged reluctor wheel should be replaced.
  • CKP sensor wire harness should be fixed or replaced if needed.
  • Change the malfunctioning camshaft position sensor.
  • The crankshaft position sensor connection that is rusted or broken should be fixed or replaced.
  • Examine and repair the crankshaft sensor’s damaged wires.
  • Change or reprogram the PCM

P0336 Code Repair Cost

FAQ Section

Where is the crankshaft position sensor located?

The crankshaft position sensor location varies according to the vehicle model. Of course, it should be close to the crankshaft, so it’s usually in front of the engine. The CKP sensor is usually attached to the timing cover. Some of them are also mounted on the side or at the rear of the engine.

How serious is the P0336 code?

Diagnostic trouble code P0336 trouble code is generally considered to be quite severe DTC. This code comes with a high potential for driving issues. That is why it is categorized as a serious DTC code. The P0336 can stall your car’s engine, and you can face a dangerous situation during heavy traffic on a major road.

CKP sensor failure can make your car unable to start. This can result in unexpected vehicle stops and unable to start your car. If your car stops halfway, then you have to find an expensive rescue to take your car to the repair center. This may also be very annoying, especially if you’re attempting to travel on a strict schedule.

Can disconnecting the battery reset the CKP sensor?

Disconnecting the battery can’t reset the CKP sensor. A sensor is a mechanical unit that works without a power source.

What causes DTC P0336?

The broken reluctor ring, faulty wirings to the sensor, misfiring, faulty PCM, or faulty CKP sensor are the most common causes of the P0336 code.

Can a crankshaft sensor be cleaned?

To clean the CKP sensor, just remove the 1 bolt which holds the sensor in its place. Remove the sensor and clean any metal or grease from the sensor.

Can I drive with a bad crankshaft position sensor?

The crankshaft speed and position are some of the most important parameters used in engine management calculations. Many engines cannot run if the crankshaft position sensor does not provide an accurate signal.

Can I drive with P0336 Code?

This trouble code is considered a severe DTC. As your PCM triggers the P0336, you should stop driving immediately. Fix this code as soon as possible to stop internal engine damage.
