What Does P001D Mean?
The PCM has detected an open circuit or general electrical fault in the Bank 2 intake (A) camshaft profile control solenoid circuit. This is the Bank 2 equivalent of P001A, affecting the opposite cylinder bank on V-configuration engines. The PCM cannot switch the intake cam profile on Bank 2.
Common Causes
35%
Open circuit in the wiring between the PCM and the Bank 2 intake cam profile solenoid
30%
Failed Bank 2 intake camshaft profile solenoid with open coil winding
20%
Disconnected or corroded connector at the Bank 2 solenoid
10%
PCM driver circuit failure for the Bank 2 cam profile output
5%
Blown fuse in the shared solenoid power supply circuit
Diagnostic Steps
1
Locate the Bank 2 intake cam profile solenoid (typically passenger side on longitudinal V-engines) and inspect the connector for damage
2
Measure solenoid resistance — should be 14-30 ohms (manufacturer specific); infinite resistance confirms an open coil
3
Check for battery voltage at the solenoid supply pin with key on; verify PCM ground control wire has continuity (less than 2 ohms end-to-end)
4
Compare Bank 2 solenoid resistance to Bank 1 solenoid resistance — they should be within 10% of each other
5
If all wiring checks pass, command the solenoid with bidirectional control while monitoring PCM driver output voltage to rule out PCM fault
Estimated Repair Cost
$80 - $600
Parts + labor, varies by vehicle and location
The PCM has detected an open circuit or general electrical fault in the Bank 2 intake (A) camshaft profile control solenoid circuit. This is the Bank 2 equivalent of P001A, affecting the opposite cylinder bank on V-configuration engines. The PCM cannot switch the intake cam profile on Bank 2.
The most common cause of P001D ("A" Camshaft Profile Control Circuit/Open Bank 2) is: Open circuit in the wiring between the PCM and the Bank 2 intake cam profile solenoid
Typical repair costs for P001D range from $80 to $600, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Bank 2 will operate on the default cam profile. Power delivery will be uneven between banks, potentially causing a slight vibration at high RPM. Safe for normal driving.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P001D to identify the root cause.
