P0345 Camshaft position sensor A circuit (bank 2)
What P0345 means
The engine computer is not receiving a usable signal from camshaft position sensor A on bank 2, the side of a V or boxer engine without cylinder 1. It uses this signal to identify cylinder position and control valve timing on that bank.
P0345 is a generic SAE J2012 code: it means the same on every make. The exact cause still depends on the car, so read the freeze-frame data before replacing parts.

Parts and labour at an independent workshop in Europe. Main dealers charge more; the cause decides the bill, not the code.
Symptoms
- Check engine light on
- Long cranking or hard starting
- Rough idle or stalling
- Power loss, especially in the mid-rpm range
- Higher fuel consumption
Common causes
- Failed camshaft position sensor
- Damaged wiring or loose, oil-soaked connector
- Damaged camshaft target wheel
- Timing chain stretched or jumped on bank 2
Can I keep driving with P0345?
Get it checked within a few days. The engine may be hard to start or stall, and variable valve timing on bank 2 may be disabled.
What to check first
- Inspect the bank 2 camshaft sensor connector and wiring for oil and damage.
- Check supply voltage, ground and signal while cranking.
- Inspect the sensor tip and target wheel.
- Check camshaft timing if other timing codes are present, then replace the sensor if needed.
