Where it lives

For P2B39, the circuit described runs through the actuator. The description of P2B39 puts it on bank 1.

Check these first

• An open in the B camshaft profile actuator B control wiring bank 1
• A failed B camshaft profile actuator B solenoid bank 1
• A bank 1 profile actuator B connector pin backed out
• A burned driver for the bank 1 profile actuator B output

What to do next

1. Scan all modules and read the B camshaft profile actuator B command bank 1
2. Inspect the bank 1 profile actuator B connector for a loose pin
3. Test the profile actuator B control circuit bank 1 for continuity
4. Measure the B camshaft profile actuator B solenoid resistance
5. Replace the B camshaft profile actuator B if the circuit is intact
6. Clear the code and retest
