P0375 Code: Timing Reference High Resolution Signal B Malfunction
🟠 Moderate severity · drivable
Drivable, but the engine may run roughly or misfire, so have it checked soon.
What P0375 means
The engine computer is getting a bad high-resolution timing signal (signal B) from the crankshaft or camshaft position sensor. This signal tells the computer exactly where the engine is so it can fire the spark plugs and fuel injectors at the right time.
Symptoms
- Check engine light is on
- Rough running or misfire
- Hard starting
- Possible stalling
Common causes
- most common: Faulty crankshaft position sensor
- common: Damaged wiring or loose connector
- less common: Damaged timing wheel or reluctor ring
