Understanding Subaru Legacy P0336 Code

If you're a Subaru Legacy owner, you may have encountered the P0336 trouble code. This code can be a source of confusion and concern, but understanding it can help you address the issue effectively. In this article, we will explore what the P0336 code means, its causes, symptoms, and how Mavyn can assist you in resolving it.

What is the P0336 Code?

The P0336 code is a diagnostic trouble code (DTC) that indicates a problem with the crankshaft position sensor (CKP) circuit. Specifically, it refers to a "Crankshaft Position Sensor A Range/Performance Problem." This sensor plays a crucial role in the engine's performance by monitoring the position and rotational speed of the crankshaft.

Common Causes of P0336 Code

Several factors can trigger the P0336 code in your Subaru Legacy. Here are some of the most common causes:

  1. Faulty Crankshaft Position Sensor: The most common reason for the P0336 code is a malfunctioning crankshaft position sensor. This sensor may fail due to wear and tear or exposure to extreme temperatures.

  2. Wiring Issues: Damaged or corroded wiring in the CKP circuit can lead to poor connectivity, resulting in the P0336 code.

  3. Faulty Engine Control Module (ECM): In rare cases, the ECM itself may be the culprit, causing incorrect readings from the crankshaft position sensor.

  4. Timing Belt Issues: If the timing belt is worn or has jumped a tooth, it can affect the crankshaft's position, leading to the P0336 code.

  5. Oil Contamination: Oil leaks can contaminate the sensor, causing it to malfunction.

Symptoms of P0336 Code

When your Subaru Legacy triggers the P0336 code, you may experience several symptoms, including:

  • Check Engine Light: The most noticeable symptom is the illumination of the check engine light on your dashboard.

  • Engine Misfires: You may notice that your engine is misfiring or running roughly, especially during acceleration.

  • Reduced Engine Performance: The vehicle may experience a decrease in power and acceleration.

  • Difficulty Starting: In some cases, the engine may have trouble starting or may not start at all.
