What Does P002D Mean?
The ECM has detected an open circuit in the 'B' camshaft profile control solenoid on Bank 2. On V-configuration engines, Bank 2 is the side not containing cylinder #1. This solenoid controls variable valve timing or lift on the exhaust camshaft of Bank 2. Symptoms include reduced engine performance, rough idle, and possible misfires on Bank 2 cylinders.
Common Causes
35%
Faulty 'B' camshaft profile control solenoid on Bank 2 (open coil)
30%
Broken or disconnected wiring in the Bank 2 solenoid circuit
20%
Corroded or loose connector at the solenoid or ECM
10%
ECM driver circuit failure for Bank 2 control
5%
Oil contamination causing solenoid valve seizure and coil burnout
Diagnostic Steps
1
Check for companion codes on Bank 1 (P002A). If both banks are affected simultaneously, suspect a shared power supply issue or ECM fault rather than individual solenoid failures.
2
Locate the 'B' camshaft profile control solenoid on Bank 2. Disconnect it and measure coil resistance — expect 7–13 ohms. An open-line reading confirms a failed solenoid.
3
With the solenoid disconnected, verify battery voltage is present on the power supply wire with key on. Then check continuity of the ECM control wire back to the ECM — should be under 1 ohm.
4
Inspect the Bank 2 harness routing for damage, especially where it crosses near exhaust components or moves with the engine. Wiggle-test connectors while monitoring for intermittent continuity.
5
If wiring and solenoid check out, command the solenoid on/off via scan tool while backprobing the ECM connector to verify the ECM is toggling the driver circuit.
Estimated Repair Cost

The most common cause of P002D ("B" Camshaft Profile Control Circuit/Open Bank 2) is: Faulty 'B' camshaft profile control solenoid on Bank 2 (open coil)
Typical repair costs for P002D range from $100 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive short distances. Bank 2 camshaft timing will default to base position, reducing performance. Avoid heavy acceleration or towing until repaired. Not a safety hazard but should be addressed to maintain engine efficiency.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P002D to identify the root cause.
