P0023 P0023 B Camshaft Position Actuator A Control Circuit/Open Bank 2
What P0023 means for you
Both sources align on a high severity.
Symptoms
- The check engine light will illuminate as the first noticeable sign of the P0023 code.
- Other symptoms can vary but may include irregular occurrences of related trouble codes.
- Drivers may experience rough engine operation.
- There may be a noticeable decrease in engine power.
- Increased fuel consumption can also be a symptom.
- Overall engine performance may decline.
Common causes
- The P0023 code can arise from various issues within the variable valve timing (VVT) and variable camshaft timing (VCT) systems.
- Faulty wiring in the VVT actuator, including both short circuits and open circuits, can trigger this code.
- Problems with the VVT oil flow control valve solenoid, such as circuit failures, may also lead to the P0023 code.
- General VVT circuit problems, including damaged or corroded wiring and poor electrical connections, can be contributing factors.
- In rare cases, a malfunctioning powertrain control module (PCM) or software update issues may cause this code.

The P0023 code indicates a malfunction in the camshaft position actuator circuit for bank 2, specifically related to the 'B' camshaft. This typically means that the engine control module (PCM) has detected that the timing of the camshaft is not being adjusted as required, which can lead to reduced engine efficiency and performance.
Frequently asked questions
While it is physically possible to drive with a P0023 code active, it is not advisable as it can lead to more severe engine problems.
The cost to repair a P0023 code can vary widely based on the specific issue, but you should expect to spend between $100 and $500, depending on parts and labor.
Common symptoms include an illuminated check engine light, rough engine running, decreased power, and increased fuel consumption.
