P2094 OBD-II Trouble Code: A Fault with the B Camshaft Position Actuator Control Circuit Low Bank 2

Check Engine Light

What the P2094 code means?

The P2094 code means that the camshaft position actuator control circuit has found low system voltage present. The Engine Control Unit (ECU) detects this low voltage fault for the camshaft position actuator bank 2 and sets the P2094 code. The ECU sends a signal to the dashboard causing the Check Engine light to be illuminated on the dashboard. Along with the Check Engine light, a failsafe mode is also set to protest the vehicle from further damage and will remain until normal voltage readings are found or the fault is repaired.

What causes the P2094 code?

  • The engine timing is out of specifications
  • Poor electrical connection
  • B camshaft position actuator wiring Harness has an open or short
  • Variable valve solenoid B failed

What are the symptoms of the P2094 code?

  • Check Engine light illuminated on the dashboard
  • Erratic idle
  • Lower than normal fuel economy
  • Lack of engine power felt

How does a mechanic diagnose the P2094 code?

  • Scans tools to check for any codes stored in the ECU including pending or history codes. Not all codes found including any freeze frame data information are found

  • Clears all codes from the ECU

  • The vehicle will not be taken on a road test to attempt to duplicate the symptoms or code

  • Performs a visual inspection looking for damaged parts or worn or broken wiring

  • Uses the scan tool to check the camshaft B bank 2 position and compares the findings to bank 1, they should be similar

  • Uses a multimeter to check for the proper voltage at the camshaft position actuator

  • Checks mechanical timing to make sure it is within specifications

Common mistakes when diagnosing the P2094 code

The most common mistakes is that missing out of specification timing can cause the P2094 code. A timing belt or chain can fail causing the timing to advance beyond specifications resulting in strange issues. Completing all steps during diagnosis will aid in finding the cause and repairing it right the first time.

How serious is the P2094 code?

The P2094 code can be serious depending on what symptoms are present. If the P2094 is caused by a failed timing chain or belt the result can be extreme engine damage.

What repairs can fix the P2094 code?

Additional comments for consideration regarding the P2094 code

If the P2094 code is seen right after a timing belt repair or a timing chain replacement timing should be checked immediately. It is possible that the engine will have jumped a tooth and this can cause extreme damage depending on the engine type.
