B Camshaft Profile Actuator Position Sensor B Circuit Low Bank 1

Where it lives

For P2C18, the circuit described runs through the sensor. The description of P2C18 puts it on bank 1.

Check these first

• A short to ground on the camshaft profile actuator position sensor B signal
• A position sensor B that lost internal resistance
• Oil at the position sensor B connector
• A pinched sensor B harness

What to do next

1. Read camshaft profile actuator position sensor B on a scan tool
2. Disconnect sensor B and see if the low reading clears
3. Test the sensor B signal wire for a short to ground
4. Inspect the sensor B harness for pinches
5. Replace position sensor B if the circuit tests good
6. Clear the code and retest
