What Does P001F Mean?
The PCM has detected high voltage on the Bank 2 intake (A) camshaft profile control solenoid circuit. This is the Bank 2 equivalent of P001C. The control circuit voltage exceeds the maximum expected value, typically due to an open ground path, short to voltage, or high-resistance solenoid.
Common Causes
30%
Open ground circuit for the Bank 2 cam profile solenoid
30%
Short to battery voltage in the Bank 2 solenoid control wire
20%
High internal resistance in the Bank 2 cam profile solenoid
15%
Corroded or loose connector pins on Bank 2 solenoid
5%
PCM output driver fault for the Bank 2 circuit
Diagnostic Steps
1
Measure the Bank 2 cam profile solenoid resistance — should be 14-30 ohms; high readings indicate approaching failure
2
With the solenoid disconnected, check the control wire for short to battery voltage — should read 0V with key on and solenoid not commanded
3
Verify the solenoid ground path resistance is below 0.5 ohms to chassis ground; clean and tighten all ground points in the circuit
4
Inspect harness routing near positive battery distribution points or starter motor cables for potential B+ shorts
5
Command the solenoid while monitoring current draw with an amp clamp — should draw 0.4-0.8A when activated; no current draw with high voltage confirms open ground
Estimated Repair Cost
$80 - $500

The most common cause of P001F ("A" Camshaft Profile Control Circuit High Bank 2) is: Open ground circuit for the Bank 2 cam profile solenoid
Typical repair costs for P001F range from $80 to $500, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Cam profile switching on Bank 2 is inoperative. The engine runs safely in default mode with diminished high-RPM output. No critical safety concern for normal driving conditions.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P001F to identify the root cause.
