P0020 P0020 "A" Camshaft Position Actuator Circuit/Open
What P0020 means for you
Both sources align on a low severity.
Symptoms
- A rough-running engine is a frequent issue linked to the P0020 code. You might notice engine stalling due to an open circuit in the oil control valve, regardless of engine speed. Stalling can occur when the vehicle is idling, and you may hear rattling noises from the engine. Additionally, there may be a noticeable drop in fuel efficiency as the bank 2 intake fails to align properly with the oil control valve. The check engine light will also be illuminated.
- Reduced engine performance
- Higher fuel consumption
Common causes
- The primary cause of a P0020 code is typically a defective variable valve timing (VVT) solenoid, which regulates oil flow based on engine speed. Another potential issue could be an obstruction within the engine, such as oil sludge, that disrupts the variable valve timing operation.
- A malfunctioning engine control module (ECM) may also be responsible, as it could send incorrect signals to the oil control valve, leading it to operate improperly. Additionally, faulty wiring connected to the oil control valve can contribute to this issue.
- Modern vehicles utilize a variable timing system to optimize the timing of intake and exhaust valves, enhancing fuel efficiency and performance. The engine control module (PCM) employs a Camshaft Position Actuator to manage the camshaft's position. If the camshaft fails to respond to the PCM's commands, it will trigger the P0020 code.

The P0020 code signifies that the bank 2 intake camshaft is not properly synchronized with the oil control valve due to a malfunctioning circuit. This issue is detected by the engine control module, which oversees the operation of the camshaft intake and oil exhaust valves. The ECM monitors the camshaft position sensor to adjust the bank 2 intake; if it identifies an electrical fault in the camshaft position actuator circuit, it will set this code.
Frequently asked questions
While it is possible to drive with a P0020 code, it is not advisable as the engine may stall unexpectedly, posing safety risks.
The cost to repair a P0020 code can vary widely based on the underlying issue, but it typically ranges from $100 to $400, depending on whether parts need to be replaced.
Symptoms of a P0020 code include rough engine operation, stalling, reduced performance, and increased fuel consumption.
