What Does P002F Mean?
The ECM has detected a high voltage condition in the 'B' camshaft profile control solenoid circuit on Bank 2. The circuit voltage exceeds the expected range, typically due to an open ground, short to battery voltage, or a failed high-impedance solenoid. Symptoms include rough idle, reduced power on Bank 2 cylinders, and poor fuel economy.
Common Causes
30%
Open ground circuit on the Bank 2 solenoid control wire
25%
Control wire shorted to battery voltage (B+)
25%
Failed camshaft profile solenoid with open coil winding
15%
Backed-out or corroded connector pin preventing ground path
5%
ECM ground driver failure for Bank 2
Diagnostic Steps
1
Monitor the Bank 2 camshaft profile control PID. Command the solenoid through duty cycle ranges and observe whether voltage remains stuck high regardless of ECM commands.
2
Disconnect the Bank 2 solenoid connector and measure the control wire voltage with key on. Near-battery voltage with solenoid disconnected suggests a short to B+ or a stuck-high ECM driver.
3
Measure solenoid coil resistance — expect 7–13 ohms. Infinite (OL) resistance means the coil is open and the solenoid must be replaced.
4
Verify ground path continuity from the solenoid connector ground pin through the harness back to the ECM. Resistance should be under 1 ohm — an open ground will cause the circuit to float high.
5
Inspect the Bank 2 harness for chafing against power supply wires. Any location where the control wire insulation is compromised near a B+ source could cause this high-voltage condition.

The most common cause of P002F ("B" Camshaft Profile Control Circuit High Bank 2) is: Open ground circuit on the Bank 2 solenoid control wire
Typical repair costs for P002F range from $100 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Drivable at reduced performance. Bank 2 VVT is disabled and cam timing will default to base position. No immediate safety risk, but repair soon to prevent reduced fuel economy and potential long-term engine wear from improper timing.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P002F to identify the root cause.
