P0020 OBD-II: "A" Camshaft Position Actuator Circuit/Open
P0020 Severity
Should you fix P0020 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 P0020?
Newer vehicles use a variable timing system to adjust the timing of the intake and exhaust valves in an effort to increase fuel efficiency and performance. The engine control module (PCM) uses a Camshaft Position Actuator to adjust the camshaft accordingly. If the Camshaft does not respond as the PCM requests, the PCM will set code P0020.
