The P0375 OBD-II code refers to a malfunction in the timing reference high-resolution signal “B”. This code signifies that there’s an issue with the signals being sent from the crankshaft position sensor (CKP) to the fuel injection control module (FICM).
What Does the P0375 Code Mean?
When the P0375 code is triggered, it indicates that the engine control module (PCM) has detected an issue with the duplicate signal of the crankshaft position sensor (CKP) that is sent to the FICM. It typically points towards a corrupt signal causing decreased engine performance.
What Causes the P0375 Code?
Several factors can cause the P0375 code, including:
- Failure of the Crankshaft Position Sensor (CKP)
- Failure of the Fuel Injection Control Module (FICM)
- Failure of the Powertrain Control Module (PCM)
- Wiring issues leading to signal corruption
What Are the Symptoms of the P0375 Code?
Common symptoms associated with the P0375 code include:
- Decreased engine performance
- Engine may not start
How Serious Is the P0375 Code?
The P0375 code is considered urgent, as it indicates significant malfunctions that can lead to severe damage to the vehicle or pose risks to driver and passenger safety. Immediate attention is necessary to prevent further issues.
How to Diagnose the P0375 Code
To diagnose the P0375 code, follow these steps:
- Use an OBD-II scanner to read the trouble codes and check for any additional codes.
- Inspect the crankshaft position sensor and its wiring for any visible damage.
- Test the CKP and FICM to ensure they are functioning correctly.
- Check the Powertrain Control Module (PCM) for any issues.
Common Repairs for the P0375 Code
Repairs for the P0375 code may include:
- Replacing the Crankshaft Position Sensor (CKP)
- Repairing or replacing the Fuel Injection Control Module (FICM)
- Fixing any wiring issues or shorts
- Replacing the Powertrain Control Module (PCM) if necessary
How Much Does It Cost to Fix the P0375 Code?
The cost to fix the P0375 code can vary widely based on the underlying issue. Typically, repairs can range from $100 to $1,500, depending on whether it’s a simple sensor replacement or a more complex electrical issue.
Can I Fix the P0375 Code Myself?
While some DIY enthusiasts may be able to address minor issues like replacing a sensor or fixing wiring, the P0375 code often requires a thorough diagnostic approach. If you are not experienced with automotive repairs, it’s advisable to seek professional assistance to ensure proper diagnosis and repair.
