How to Diagnose and Fix the P0336 Code

A P0336 code is an OBD-II trouble code that indicates a malfunction in the crankshaft position sensor. This code is usually caused by a bad or failing crankshaft position sensor, although other possible causes include wiring problems or damage to the connector pins. Fortunately, it is possible to fix a P0336 code by replacing the faulty crankshaft position sensor and ensuring that the wiring and connectors are in good condition.

To begin, you should locate and remove the faulty crankshaft position sensor. If necessary, you may need to consult your vehicle’s repair manual for instructions on how to do this. Once you have removed the faulty sensor, install a new one. Make sure that all wiring and connectors are in good condition before reinstalling the new sensor.

Finally, clear the trouble codes from your vehicle’s computer using an OBD-II scanner. Once this is done, start your engine and check for any remaining codes. If all of the codes have been cleared successfully then your vehicle should be running normally again.


When it comes to cars, one of the most common issues that can arise is a check engine light. This is usually due to a problem within the car’s computer system and can be caused by a variety of different issues. One of the most common codes associated with this issue is P0336, which indicates that there is a problem with the crankshaft position sensor. In this article, we will discuss what P0336 means and how to fix the code.

Symptoms of P0336

The symptoms of P0336 include engine misfires, rough idling, and stalling. It can also cause a decrease in fuel economy and acceleration, as well as a lack of power when accelerating. Additionally, you may hear sounds coming from your engine that weren’t there before, such as knocking or ticking noises.

Diagnosis of P0336

In order to diagnose the code P0336, you will need to connect an OBD-II scanner to your car’s computer system. This will allow you to read the diagnostic trouble codes that have been stored in your vehicle’s memory. Once you have identified the code as P0336, you will need to further investigate its cause in order to determine how to fix it.

Causes of P0336

The most common cause for code P0336 is a faulty or failing crankshaft position sensor (CPS). Other potential causes include wiring problems, an incorrect installation of the CPS, or even an issue with the PCM (Powertrain Control Module).

How to Fix Code P0336?

In order to fix code P0336, you will need to inspect and possibly replace the crankshaft position sensor:

Step 1: Inspect the Crankshaft Position Sensor – The first step is to inspect the CPS for any signs of damage such as corrosion or physical damage. If there are no signs of damage then move on to step two below.

Step 2: Replace the Crankshaft Position Sensor – If there are signs of damage or if you suspect that it may be faulty then it’s best to replace it with a new one. Make sure that you purchase a CPS from a reputable source in order for it to function properly in your vehicle’s computer system.

How to Fix P0336 Code in Automobiles

Fixing the code P0336 in automobiles can be a daunting task, but with the right steps, it can be done quickly and efficiently. The following steps outline the process for diagnosing and repairing this common issue.

Step 1: Diagnose the Problem

The first step in fixing the code P0336 is to diagnose the problem. This will involve checking the engine control unit (ECU) for any fault codes that have been stored. In addition, it is important to check all of the wiring and connectors that are related to the crankshaft position sensor. If any of these components are damaged or not working correctly, they will need to be replaced before moving on to the next step.

Step 2: Clean All Components

Once all of the components have been checked and any faulty ones have been replaced, it is time to clean all of them. This includes any wiring or connectors that may have dirt or grime on them. It is important to use a non-abrasive cleaner so as not to damage any of these components. Once everything is cleaned, it is time to move on to the next step.

Step 3: Check the Wiring and Connectors

After cleaning all of the components, it is important to check all of the wiring and connectors that are related to the crankshaft position sensor. This includes checking for any corrosion or damage that may have occurred over time. If there is any corrosion or damage, it must be removed before moving on to replacing any faulty parts.

Step 4: Replace Damaged Wiring or Connectors

If there are any damaged wiring or connectors related to the crankshaft position sensor, they must be replaced with new ones before continuing with repairs. It is important to make sure that they are properly connected and secured so as not to cause further damage or problems down the line.

Step 5: Verify Repairs are Effective

Once all repairs have been completed, it is important to verify that they are effective by running a diagnostic test on the vehicle’s ECU again. The results should show no faults with code P0336 if everything was done correctly and effectively repaired.

Common Problems Related To Code P0336 in Automobiles

When dealing with code P0336, two common problems can occur in automobiles; faulty crankshaft position sensors and faulty wiring and connectors. A faulty crankshaft position sensor can cause inaccurate readings from other sensors which can lead to incorrect engine performance as well as poor fuel economy due poor combustion efficiency from incorrect air/fuel ratios being sent out by erroneous data from other sensors downstream from this component malfunctioning component . Faulty wiring/connector issues can lead too short circuits causing voltage spikes which fry computer hardware components such as sensors/relays/injectors etc leading too poor performance/increased fuel consumption etc…
