How to Fix the P0335 Error Code in Your Kia Soul
If you're a Kia Soul owner and your car's check engine light has turned on with a P0335 error code, you might be wondering what it means and how to fix it. The P0335 code is a standard OBD-II trouble code that indicates a malfunction with the crankshaft position sensor (CPS) circuit. In this article, we'll guide you through understanding what this error code means, why it occurs, and how to troubleshoot it effectively.
What is the P0335 Error Code?
The P0335 error code is triggered when the Engine Control Module (ECM) detects a problem with the signal coming from the crankshaft position sensor. The crankshaft position sensor plays a crucial role in monitoring the position and rotational speed of the crankshaft. This information is essential for the ECM to control engine timing and fuel injection.
Common Symptoms of the P0335 Error Code
When the P0335 error code is present, you may notice one or more of the following symptoms:
- Engine stalling or difficulties starting
- Reduced fuel efficiency
- Engine misfires
- Rough running engine
- The check engine light is on
Possible Causes of the P0335 Error Code
Several issues can lead to the P0335 error code in your Kia Soul:
- Faulty crankshaft position sensor
- Damaged or frayed sensor wiring
- Poor electrical connections at the sensor
- Faulty ECM (less common)
Step-by-Step Troubleshooting Guide
Step 1: Inspect the Crankshaft Position Sensor
Check the crankshaft position sensor for any visible signs of damage or wear. Look for cracks, oil contamination, or burnt marks. Also, ensure that the sensor is securely mounted.
Step 2: Check the Wiring and Connectors
Examine the wiring leading to and from the crankshaft position sensor. Look for any signs of fraying, corrosion, or disconnections. Ensure all connectors are tight and free from corrosion.
Step 3: Test the Crankshaft Position Sensor
Use a multimeter to test the crankshaft position sensor’s resistance and compare it to the manufacturer's specifications. An out-of-specification reading indicates a faulty sensor that needs replacement.
Step 4: Check the Engine Control Module
Although rare, a faulty ECM can cause the P0335 error code. It’s advisable to consult with a professional mechanic or an automotive electrician to diagnose ECM issues.
Step 5: Clear the Error Code and Test Drive
After making any repairs or replacements, clear the error code using an OBD-II scanner. Then, take your Kia Soul for a test drive to ensure that the issue is resolved and the P0335 code does not reappear.
