What does the P000C “A” Camshaft Position Slow Response Bank 2 mean?
P000C indicates a “camshaft position slow response” issue. This means the camshaft isn’t aligning properly with the crankshaft, which can cause the engine to misfire by not timing the fuel injector and spark plug ignition correctly. Specifically, P000C points to the Intake camshaft for Bank 2.
When the P000C Triggers?
The camshaft position sensor measures the camshaft’s position and sends this data to the Engine Control Unit (ECU). The ECU, in turn, uses this information to control the timing of fuel injection, spark plug ignition, and variable valve timing.
If the ECU detects that the camshaft in Bank 2, Intake is out of alignment with the crankshaft, it triggers the P000C code.
What is Bank 2-Intake?
In engines with multiple banks, such as V6 or V8 configurations, Bank 2 refers to the opposite side where cylinder #1 is located.
For Dual Overhead Camshaft (DOHC) engines, each bank has two camshafts: an intake camshaft (“A”) and an exhaust camshaft (“B”). The intake camshaft controls the intake valves, while the exhaust camshaft regulates exhaust flow.
Where is the P000C Sensor Located?
The camshaft position or P000C sensor’s location varies by make and model. Generally, these sensors are located close to the camshafts, either on the valve cover or in the cylinder head.
To accurately find and identify your camshaft position sensor, consult your vehicle’s manual.
How to Reset the P000C Code?
Sometimes, codes like P000C may appear following recent maintenance and may clear on their own. To reset the code, use an OBD-II scanner by following these steps:
- Step 1: Connect the scanner to your vehicle’s diagnostic port.
- Step 2: Clear the trouble codes following the scanner’s instructions.
If the P000C code reappears, this likely points to a more persistent issue requiring further diagnosis.
Possible Root Causes of P000C
Some common root causes of the P000C error code include:
1. Erratic Camshaft Position Due to Low Oil Pressure
The camshaft timing system relies on proper oil pressure to move the cam phasers. If the engine oil is low, dirty, or degraded, or if the oil pump is weak, the camshaft actuator may not respond quickly enough. This can cause slow or erratic camshaft movement, triggering the P000C code.
Fix: Check engine oil level, condition, and pressure. Replace with the correct grade of oil as per OEM specification. If oil pressure is too low, inspect the oil pump and lubrication system.

2. Oil flow restrictions in the passages or VCT (Variable Camshaft Timing) valve body
The VCT system depends on clean and unrestricted oil flow to adjust the camshaft timing. If there is sludge buildup, varnish deposits, or debris inside the oil passages or the VCT valve body, the oil flow can be restricted. This prevents the camshaft actuator from moving smoothly, leading to a slow camshaft response and triggering the P000C code.
Fix: Perform an engine flush or clean the oil passages if necessary. Inspect and clean the VCT valve body. Replace the oil control valve (VVT solenoid) if sticking or clogged.
3. Faulty Camshaft Actuator (Phaser)
The camshaft actuator, also called the phaser, adjusts camshaft position by controlling oil flow. A worn, stuck, or internally damaged actuator can cause the camshaft to respond slower than expected, leading to P000C.
Fix: Inspect the camshaft actuator for mechanical wear or sticking. Replace if faulty.

4. Malfunctioning VVT Solenoid (Oil Control Valve)
The VVT solenoid directs oil pressure to the camshaft actuator. If the solenoid is sticking, clogged, or electrically failing, it can delay camshaft movement and cause a slow response.
Fix: Test the solenoid with a multimeter for resistance and operation. Clean or replace if defective.

5. Stretched or Misaligned Timing Chain/Belt
A stretched timing chain or worn timing belt can cause improper synchronization between the crankshaft and camshaft. This results in delayed camshaft positioning, triggering the P000C error.
Fix: Inspect the timing chain/belt, guides, and tensioner. Replace worn components.

6. Faulty Camshaft or Crankshaft Position Sensor
If the camshaft or crankshaft sensor sends erratic or inaccurate signals, the ECM cannot properly monitor camshaft response. This can mimic a slow response condition and set P000C.
Fix: Test both sensors with a scan tool or multimeter. Replace if readings are unstable or out of spec.

7. Faulty Camshaft or Crankshaft Position Sensor
The VCT phaser (also called cam phaser) is responsible for adjusting camshaft timing based on oil pressure and ECM commands. If the phaser is mechanically damaged, worn, or stuck, it can’t adjust the camshaft quickly, leading to a slow response condition and triggering code P000C.
Fix: Inspect the VCT phaser for wear, binding, or internal failure. Replace the phaser if damaged.
