P2091 Dodge Code - 'B' Camshaft Position Actuator Control Circuit High Bank 1

Quick Answer

The P2091 diagnostic trouble code (DTC) for Dodge vehicles indicates a problem with the 'B' Camshaft Position Actuator Control Circuit High Bank 1. Common causes include Faulty Camshaft Position Actuator: The actuator itself may be malfunctioning, leading to high voltage readings in the circuit, Wiring Issues: Damaged or corroded wiring connecting the camshaft position actuator to the engine control module can cause high voltage readings, Electrical Short: A short circuit in the wiring harness can disrupt the proper functioning of the camshaft position actuator. Severity is Low - monitor the vehicle and repair when practical. The vehicle can usually be driven if no severe symptoms are present, but symptoms should be checked before extended driving.

Common Causes of P2091 Dodge

  1. Faulty Camshaft Position Actuator: The actuator itself may be malfunctioning, leading to high voltage readings in the circuit.
  2. Wiring Issues: Damaged or corroded wiring connecting the camshaft position actuator to the engine control module can cause high voltage readings.
  3. Electrical Short: A short circuit in the wiring harness can disrupt the proper functioning of the camshaft position actuator.
  4. Engine Control Module (ECM) Failure: If the ECM is not sending or receiving the correct signals, it can lead to high voltage in the control circuit.
  5. Mechanical Timing Issue: A mechanical problem with the camshaft itself can cause the actuator to read high voltage.

Symptoms of P2091 Dodge

  1. Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
  2. Rough Idle: An irregular or rough idle may be experienced due to the improper timing of the camshaft.
  3. Reduced Engine Performance: The vehicle may exhibit a decrease in power and overall performance due to the timing issue.
  4. Increased Fuel Consumption: Inefficient timing can result in increased fuel consumption as the engine works harder to compensate.
  5. Engine Misfires: Misfires may occur as a result of the camshaft position being out of sync with the crankshaft.

How to Fix P2091 Dodge

  1. Diagnose the Issue: Use a scan tool to read the code and perform further diagnostics to pinpoint the exact cause of the problem.
  2. Inspect Wiring: Check the wiring harness for any damage, corrosion, or shorts that may be affecting the circuit.
  3. Test Camshaft Position Actuator: Test the actuator to ensure it is functioning properly and replace if necessary.
  4. Check ECM: Verify that the ECM is sending and receiving signals correctly, and replace if needed.
  5. Clear Codes: After completing the repair, clear the DTC and test drive the vehicle to ensure the issue has been resolved.

Cost to Fix P2091 Dodge
