Is It Safe to Drive With a P0345 Code?

Possible Causes of P0345
A P0345 code can be triggered by faults across several systems. Identifying the exact root cause requires proper diagnostic equipment and live data — not just reading the code.
Cam Sensor Wiring Fault — Bank 2
Wiring or connector to bank 2 cam sensor is damaged.
Cam Sensor Failure — Bank 2
Bank 2 sensor itself has failed.
Timing Component Issue
Fault in VVT system on bank 2 affecting sensor readings.
Oil Pressure Fault
Low oil pressure affecting bank 2 VVT and sensor signal.
Why we don't list the exact part: A P0345 code tells you what's happening but not why. Replacing parts based on the code alone is the most common way drivers waste money. A proper diagnosis identifies the specific cause first.

P0345 and Your MOT
A stored P0345 fault code will cause your car to fail its MOT. The engine management light will be illuminated during the test — an automatic failure under current MOT standards. Even if the light temporarily clears, the code remains in ECU memory and can be read by testers.
Get the fault diagnosed and repaired first, then have the code cleared and confirm the light stays off before booking your MOT.
