P2089 code definition

A Camshaft Position Actuator Control Circuit High Bank1

What the P2089 code means

The P2089 code means that the A camshaft position actuator was found to have high voltage. The vehicle’s electronic control unit (ECU) detects this high voltage for the bank 1 sensor A and causes the P2089 code to be set. Once this code is set, the Check Engine Light will be visible on the dashboard. In addition to the warning light, the ECU sets a failsafe mode to prevent damage to the vehicle. The failsafe mode stays until a normal voltage range is detected or the fault is repaired.

What causes the P2089 code?

  • Open or short in the camshaft position actuator wiring harness
  • Variable camshaft solenoid bank 1 faulty
  • Poor electrical connection
  • Engine timing is incorrect

What are the symptoms of the P2089 code?

  • Check Engine Light triggered
  • Poor idle
  • Lower than normal fuel economy
  • Take a few tries to start
  • Poor acceleration.

How does a mechanic diagnose the P2089 code?

  • The first step any qualified technician will take is to check for any codes stored in the ECU including pending or history codes. Each and every code will be noted along with the freeze frame data from each.

  • Next, all codes will be cleared and a test drive performed. On the test drive the technician will try to duplicate the conditions from the code setting in the first place.

  • After the road test confirms that P2089 is present, a visual inspection will be performed looking for any obviously damaged components or worn wiring.

  • Next, the technician will use a scan tool to check the camshaft sensor data stream readings as well as the timing advance.

  • Next, a multimeter will be used to check for the proper voltage present at the camshaft position actuator.

  • Lastly, the timing will be checked on the vehicle to check for a skipped tooth on the timing belt or chain.

Common mistakes when diagnosing the P2089 code

The most common mistake with the P2089 code is failure to follow the diagnostic procedures or the order of steps. If steps are skipped, the vehicle can easily be misdiagnosed leading to wasting time and money.

How serious is the P2089 code?

The P2089 code will not prevent the vehicle from being driven once the code has been triggered. However, any Check Engine Light found should be repaired as soon as possible. If the car runs poorly it should not be driven until it has been repaired, for safety reasons.

What repairs can fix the P2089 code?

  • Repairing or replacing the wiring harness
  • Replacing the variable camshaft solenoid for bank 1
  • Resolving any poor electrical connections
  • Repairing the engine timing

Additional comments for consideration regarding the P2089 code

If the P2089 code is seen after a timing belt or timing chain repair, suspect that the timing has been advanced one tooth or more when the job was performed. If this happens, the pistons can hit the valves on interference fit engines, which causes extreme damage.
