This summary uses the existing diagnostic information shown in full below.
This code means that something is wrong with a part of the engine that helps control how fast the camshaft spins. It's like when a toy car's wheels get stuck and can't turn properly.
The engine control module (ECM) has detected a high voltage condition in the control circuit for the camshaft profile actuator B on bank 2.
The P2B38 code indicates a problem with the camshaft profile actuator B control circuit on bank 2. This actuator is responsible for adjusting the camshaft's position to optimize engine performance. A high voltage condition suggests an electrical issue, such as a short circuit or a faulty actuator.
• Check Engine Light is on
• Poor engine performance
• Rough idling
• Faulty camshaft profile actuator
• Wiring issues such as short circuits
• Faulty ECM
Camshaft: A shaft with cams that rotates to open and close engine valves.
Actuator: A device that causes a machine or other device to operate.
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for damage.
• Test the camshaft profile actuator for proper operation.
• Replace the faulty camshaft profile actuator.
• Repair or replace damaged wiring or connectors.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Wrench set

Moderate
• Chevrolet Silverado
• GMC Sierra
• Cadillac Escalade
• Regular maintenance checks
• Inspect wiring for wear and tear
• Ensure proper oil levels and quality
Engine Performance
• Do not ignore the check engine light.
• Have the vehicle inspected by a professional.
• Avoid driving the car until the issue is resolved.
Check with your vehicle manufacturer for warranty coverage on engine components.
This code has been associated with camshaft actuator issues in vehicles with variable valve timing systems.
Moderate – It's important to address this issue promptly to avoid further engine damage.
Driving with a malfunctioning engine component can lead to safety hazards and is not recommended.
• Engine at operating temperature
• Vehicle in park or neutral
The camshaft profile actuator is located on the engine's cylinder head, on bank 2.
Q: What does 'bank 2' mean?
A: Bank 2 refers to the side of the engine opposite to bank 1, which is usually the side without cylinder 1.
Q: Can I drive with a P2B38 code?
A: It's not recommended to drive with this code as it can lead to engine performance issues.
