B Camshaft Position Actuator A Control Circuit/Open Bank 2
This code means there's a problem with a part of the engine that helps control the timing of the engine's valves. It's like a conductor in an orchestra not being able to direct the musicians properly.
The P0023 code indicates an issue with the camshaft position actuator circuit for the exhaust camshaft on bank 2. This could be due to an electrical problem or a mechanical failure.
The P0023 code is triggered when the Engine Control Module (ECM) detects an open or malfunction in the camshaft position actuator circuit for the exhaust camshaft on bank 2. This actuator is responsible for adjusting the camshaft timing to optimize engine performance.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the camshaft position actuator for proper operation.
• Replace the camshaft position actuator if faulty.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools

Moderate
• Chevrolet Silverado
• Ford F-150
• Toyota Camry
• Regular maintenance of the engine.
• Timely replacement of engine oil and filters.
• Regular inspection of electrical connections.
Sensor Issue
• Do not ignore the Check Engine Light.
• Seek professional diagnosis if unsure.
• Avoid driving the vehicle for extended periods with this code active.
Check with your vehicle manufacturer; some powertrain warranties may cover this issue.
The P0023 code has been commonly reported in vehicles with variable valve timing systems, especially as they age.
Moderate – Should be addressed soon to prevent further engine issues.
Driving with a malfunctioning engine can lead to further damage and may not comply with emissions regulations.
• Engine at operating temperature
• Vehicle in park or neutral
The camshaft position actuator is typically located near the camshaft on the engine, on bank 2, which is usually the side of the engine opposite the number one cylinder.
Q: Can I drive with a P0023 code?
A: It's not recommended to drive for long periods with this code as it can lead to further engine damage.
Q: How can I reset the P0023 code?
A: You can reset the code with an OBD-II scanner, but it's important to fix the underlying issue first.
