What Does P000C Mean?
P000C indicates that the 'A' camshaft (typically the intake camshaft) on Bank 2 is responding too slowly to commanded position changes. This is the Bank 2 counterpart of P000A. The ECM detects that the Bank 2 intake cam phaser is sluggish when transitioning between advance and retard positions. Symptoms may include reduced power from the Bank 2 cylinders, slight hesitation on acceleration, and minor fuel economy degradation.
Common Causes
30%
Sludge or debris restricting oil passages to the Bank 2 intake VVT actuator
25%
Bank 2 intake VVT solenoid sticking or responding slowly due to internal contamination or wear
20%
Incorrect oil viscosity or degraded oil reducing hydraulic response of the VVT system
15%
Worn Bank 2 intake cam phaser with internal vane seal leakage
10%
Low oil pressure from a worn oil pump or partially clogged oil pickup tube
Diagnostic Steps
1
Monitor the Bank 2 intake camshaft actual position vs. desired position in live data — compare response time to Bank 1. If Bank 2 is significantly slower, the issue is bank-specific.
2
Remove and inspect the Bank 2 intake VVT solenoid — check the mesh screen filter for debris or sludge. Compare its condition to the Bank 1 solenoid.
3
Verify engine oil level and condition. If an oil change is overdue, perform a fresh oil and filter change with the correct viscosity and clear codes. Re-evaluate after 50 miles of driving.
4
Perform an oil pressure test and compare to specifications — if pressure is low across both banks, suspect the oil pump. If Bank 2 specific, check for a restricted oil passage.
5
Command the Bank 2 intake VVT solenoid through duty cycle steps (0%, 25%, 50%, 75%, 100%) and monitor cam position response time at each step.

The most common cause of P000C ("A" Camshaft Position Slow Response Bank 2) is: Sludge or debris restricting oil passages to the Bank 2 intake VVT actuator
Typical repair costs for P000C range from $100 to $1,200, depending on the vehicle, location, and whether you do it yourself or go to a shop.
Safe to drive with minor performance loss. Not an immediate safety hazard, but should be addressed within a reasonable timeframe to prevent escalating cam phaser wear and potential timing-related engine damage.
Start by connecting an OBD2 scanner to read the code and any freeze frame data. Then follow the diagnostic steps specific to P000C to identify the root cause.
