  1. Check Engine Light illuminated on the dashboard
  2. Rough idling or engine misfires
  3. Reduced fuel efficiency
  4. Engine stalling or hesitation during acceleration
  5. Loss of power or performance

How to Fix P2091

  1. Begin by conducting a visual inspection of the exhaust camshaft position actuator solenoid and its wiring for any visible damage, corrosion, or loose connections.
  2. Use a multimeter to test the voltage and resistance of the actuator solenoid and its circuit to identify any anomalies.
  3. Replace the exhaust camshaft position actuator solenoid if it is found to be faulty, ensuring proper installation and connection.
  4. Clear the diagnostic trouble codes from the vehicle's ECM using a scan tool and perform a test drive to ensure the issue has been resolved.
  5. If the problem persists, further diagnostics may be required to identify and address any underlying issues with the wiring, connections, or ECM.

Cost to Fix P2091

The typical repair costs for addressing a P2091 code can vary depending on the specific cause of the issue and the vehicle's make and model. In general, the cost of replacing the exhaust camshaft position actuator solenoid can range from $150 to $300, including parts and labor. Additional costs may apply if further diagnostics or repairs are needed for related components. It's important to consider the specific diagnosis time and labor rates at auto repair shops in your area to get a more accurate estimate for this repair.

When is the Code Detected?

The Powertrain Control Module (PCM) monitors the VCT circuit for high and low voltage. The test fails if the voltage exceeds a calibrated limit for a calibrated amount of time.
