P005D — B Camshaft Profile Control Stuck On, Bank 2

Severity: medium Drive with care, to a shop

What P005D means

P005D means the engine computer found that the B camshaft profile control on Bank 2 stays in the on position even when it commands otherwise. This system, whether variable valve timing or cam profile switching, uses a solenoid to direct oil pressure to shift cam timing or lift. If the actuator doesn't return to its default state, the PCM sets this code.

Symptoms

  • Check Engine light on
  • Reduced power and sluggish acceleration
  • Poor fuel economy
  • Rough idle or hesitation
  • Unusual noises from the top of the engine

Possible causes

  1. Faulty camshaft profile control solenoid or actuator
  2. Low, wrong-grade or contaminated engine oil
  3. Damaged wiring or poor connection at the solenoid connector
  4. Mechanical binding or blockage in the VVT system
  5. Rarely, a faulty PCM

How to diagnose

  1. Scan all codes and freeze-frame data and look for other valve timing codes
  2. Check oil level, condition and that it matches the manufacturer's spec
  3. Inspect the Bank 2 solenoid connector and harness for damage, corrosion and oil intrusion
  4. Measure solenoid resistance and compare with factory specs
  5. Check power, ground and control signal at the solenoid connector
  6. Run a scan tool active test and compare commanded and actual cam position
  7. Remove the solenoid and check for a sticking plunger or a clogged screen
  8. If needed, inspect the cam phaser and camshaft drive for mechanical problems

Common fixes

  • Replace the camshaft profile control solenoid or actuator
  • Repair wiring or replace a damaged connector
  • Change the oil and filter with the specified oil and clean the screens
  • Repair internal VVT faults such as the phaser or camshaft drive

Questions and answers

What does P005D mean?

The PCM sees the B camshaft profile control on Bank 2 stuck in the on position. The usual culprits are the solenoid, engine oil or wiring.

Can I drive with P005D?

Briefly, to get to a shop. The engine may lose power and use more fuel. If you hear knocking or oil pressure drops, stop driving.

Will an oil change fix P005D?

Sometimes, if low or dirty oil is keeping the VVT system from working. Still, check the solenoid and wiring as well.

This is general information about the code. The meaning can differ between makes and models: a scan tool and the repair manual for your car will show the exact cause.
