DTC P2008: Short Runner Solenoid Circuit: Testing

  1. Turn ignition on, engine not running. With the DRBIII® scan tool, read DTCs and record the related freeze frame data. Is the Good Trip counter displayed and equal to zero? If yes, go to next step. If no, see INTERMITTENT CONDITION  under SELF-DIAGNOSTIC SYSTEM.
  2. Turn the ignition off. Disconnect the SRV solenoid harness connector. Turn the ignition on. Using a 12-volt test light, connect one end to the ASD relay output circuit and the other end to the SRV solenoid control circuit at the SRV solenoid harness connector. With the DRBIII® scan tool, actuate the SRV solenoid. Does the 12-volt test light flash on and off? If yes, replace the SRV solenoid. If no, go to next step.
  3. Ensure the SRV solenoid is still actuated. Using a 12-volt test light connected to ground, probe the ASD relay output circuit in the SRV solenoid harness connector. Does the test light illuminate brightly? If yes, go to next step. If no, repair the ASD relay output circuit.
  4. Turn the ignition off. Disconnect the PCM harness connectors. Disconnect the SRV solenoid harness connector. Measure the resistance between the SRV solenoid control circuit and ASD relay output circuit in the SRV solenoid connector. Is the resistance below 5.0 ohms? If yes, repair the SRV solenoid control circuit for a short to the ASD relay output circuit. If no, go to next step.
  5. Turn the ignition off. Disconnect the PCM harness connectors. Disconnect the SRV solenoid harness connector. Measure the resistance between ground and the SRV solenoid control circuit at the SRV solenoid harness connector. Is the resistance below 100 ohms? If yes, repair the short to ground in the SRV control circuit. If no, go to next step.
    6. CAUTION: Do not probe the PCM harness connectors. Probing the PCM harness connectors will damage the PCM terminals resulting in poor terminal-to-pin connection. Use Miller Special Tool (8815) when performing diagnosis at PCM harness connectors.
  6. Turn the ignition off. Disconnect the PCM harness connectors. Disconnect the SRV solenoid harness connector. Measure the resistance of the SRV solenoid control circuit from the SRV solenoid harness connector to the appropriate terminal of the Miller Special Tool (8815). Is the resistance below 5.0 ohms? If yes, go to next step. If no, repair the open in the SRV control circuit.
    7. NOTE: Before continuing, check the PCM harness connectors for corrosion, damage or terminal push out. Repair as necessary.
  7. There are no possible causes remaining, replace PCM. Program the new PCM. See PROGRAMMING .

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
