    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. Install the PCM Pinout Box 8815 to perform diagnosis.
    1. Measure the resistance of the (K236) SRV Control circuit between the Short Runner Valve Assembly harness connector and the appropriate terminal of PCM Pinout Box 8815.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go to step  5

      No 

  5. (F856) 5 VOLT SUPPLY CIRCUIT OPEN OR HIGH RESISTANCE

    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. Install the PCM Pinout Box 8815 to perform diagnosis.
    1. Measure the resistance of the (F856) 5 Volt Supply circuit between the Short Runner Valve Assembly harness connector and the appropriate terminal of PCM Pinout Box 8815.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go to step  6

      No 

  6. (K235) SRV SIGNAL CIRCUIT OPEN OR HIGH RESISTANCE

    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. Install the PCM Pinout Box 8815 to perform diagnosis.
    1. Measure the resistance of the (K235) SRV Signal circuit between the Short Runner Valve Assembly harness connector and the appropriate terminal of PCM Pinout Box 8815.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go to step  7

      No 

  7. (K900) SENSOR GROUND CIRCUIT OPEN OR HIGH RESISTANCE

    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. Install the PCM Pinout Box 8815 to perform diagnosis.
    1. Measure the resistance of the (K900) Sensor Ground circuit between the Short Runner Valve Assembly harness connector and the appropriate terminal of PCM Pinout Box 8815.

      Is the resistance below 5.0 Ohms?

      Yes 

      • Go to step  8

      No 

  8. SHORT RUNNER VALVE ASSEMBLY

    1. Connect the Powertrain Control Module (PCM) harness connector.
    2. Turn the ignition on.
    3. With the scan tool, actuate the SRV Solenoid Control State to toggle.
    4. Using a 12-volt test light connected to 12 volts, check the (K236) SRV Control circuit in the Short Runner Valve Assembly harness connector.
      NOTE: If the DTC is active, the actuation test may not be allowed by the PCM. If may be necessary to clear the DTCs before starting the actuation.
      NOTE: The test light should illuminate on and off with the actuation.

      Does the test light illuminate on and off with the actuation?

      Yes 

      No 

      • Go to step  9
  9. POWERTRAIN CONTROL MODULE (PCM) 
    1. Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Short Runner Valve Assembly and the Powertrain Control Module (PCM).
    2. Look for any chafed, pierced, pinched, or partially broken wires.
    3. Look for broken, bent, pushed out or corroded terminals.
    4. Perform any Technical Service Bulletins that may apply.
