P0025 OBD-II: "B" Camshaft Position - Timing Over-Retarded

P0025 Severity

Urgent

Should you fix P0025 yourself?

Identifying an OBD code is just the start of a complete diagnostic routine. Most trouble codes are caused by a sensor reporting a value that is out of range. Just replacing a sensor may not fix underlying issues. Be sure to understand the code, the part or system in your car that the code refers to, and the risks of delaying professional repair.

Proper diagnosis will save you time and money on unnecessary repairs.

Urgent codes indicate immediate action is necessary. These are urgent and significant malfunctions that can cause severe damage to the vehicle or harm the driver and passengers.

What causes OBD-II fault code P0025?

The engine control module (PCM) uses a signal from the camshaft position sensor to determine the proper time to fire the fuel injector and ignite the spark plug. The PCM compares this signal to the >signal from the crankshaft to determine if the engine is timed properly. Newer vehicle's use a variable timing system to adjust the timing of the camshaft in relation to the crankshaft to increase fuel efficiency and performance. If the Camshaft is not in the proper position relative to the crankshaft, the PCM will set code P0025.
