Severity: Fix right away. Driving risks expensive damage or a breakdown.
The camshaft position sensor on bank 1 is working, but its signal does not line up with the crankshaft signal the way the computer expects.
Check the oil level and the sensor, and have the timing components inspected by a mechanic.
A timing mismatch can mean the chain or belt has stretched. Do not drive far — timing failure can wreck the engine.
Avoid driving until it is checked — towing is the safer choice. A timing mismatch can mean the chain or belt has stretched. Do not drive far — timing failure can wreck the engine.
The most common causes are: Failing camshaft position sensor; Stretched timing chain or belt; Worn timing components; Low oil pressure affecting variable valve timing. A scan tool and a visual check of the parts above is where a technician starts.
