Diagnostic Test

CHECK FOR AN ACTIVE DTC
1. Turn the ignition on.
2. With the scan tool, read and record DTCs and Freeze Frame data on the repair order.
  Is the DTC active or pending?
  
  Yes
  - Go To 2
  No
  - Perform the INTERMITTENT CONDITION diagnostic procedure. Refer to INTERMITTENT CONDITION .
CHECK FOR HIGH RESISTANCE IN THE (K164) FUEL TEMP SIGNAL CIRCUIT
1. Turn the ignition off.
2. Disconnect the Fuel Pressure Sensor harness connector.
  NOTE:
  The Fuel Temperature Sensor is combined inside the Fuel Pressure Sensor on the low pressure side of the fuel system.
3. Disconnect the PCM C1 harness connector.
4. Measure the resistance of the (K164) Fuel Temp Signal circuit between the Fuel Pressure harness connector and the PCM C1 harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Go To 3
  No
  - Repair the high resistance in the (K164) Fuel Temp Signal circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
CHECK FOR HIGH RESISTANCE IN THE (K917) SENSOR GROUND CIRCUIT
1. Measure the resistance of the (K917) Sensor Ground circuit between the Fuel Pressure harness connector and the PCM C1 harness connector.
  Is the resistance below 3.0 Ohms?
  
  Yes
  - Replace the Fuel Pressure Sensor in accordance with the Service Information.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
  No
  - Repair the high resistance in the (K917) Sensor Ground circuit.
  - Perform the POWERTRAIN VERIFICATION TEST. Refer to POWERTRAIN VERIFICATION TEST .
