What Does P002E Mean?
The ECM has detected a low voltage condition in the 'B' camshaft profile control solenoid circuit on Bank 2. The voltage is below the expected threshold, indicating a short to ground or excessive current draw in the circuit. The driver may notice reduced engine performance, rough idle, and an illuminated Check Engine Light.
Common Causes
35%
Wiring shorted to ground between ECM and Bank 2 solenoid
30%
Internally shorted camshaft profile control solenoid on Bank 2
20%
Corroded connector allowing moisture-induced short to ground
10%
ECM internal driver fault on Bank 2 circuit
5%
Damaged wire insulation near engine ground point
Diagnostic Steps
1
Monitor live data for the Bank 2 'B' camshaft profile solenoid. Compare commanded duty cycle versus actual response — a consistently low voltage reading confirms the fault.
2
Disconnect the solenoid and measure the control wire voltage with key on engine off. If voltage rises to normal with solenoid disconnected, the solenoid is internally shorted. If voltage stays low, the harness has a short to ground.
3
Measure solenoid coil resistance (expect 7–13 ohms) and check each terminal to the solenoid body — readings under 10k ohms indicate an internal short to ground.
4
Trace the wiring harness from the solenoid to the ECM, inspecting for bare wire contact with grounded metal surfaces. Check where the harness passes through grommets, brackets, and near the engine block.
5
If the solenoid and wiring test good, verify the power supply fuse and relay for the VVT system are functioning properly, as a low supply voltage can also cause this condition.

The most common cause of P002E ("B" Camshaft Profile Control Circuit Low Bank 2) is: Wiring shorted to ground between ECM and Bank 2 solenoid
Typical repair costs for P002E range from $100 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
The vehicle can be driven short distances at moderate speeds. Bank 2 VVT will be disabled, causing reduced power and efficiency. Not immediately dangerous, but sustained high-load driving should be avoided.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P002E to identify the root cause.
