Diagnostic Test
WARNING: This page is about a different variant/trim than selected.
- CHECK FOR AN ACTIVE DTC
- Turn the ignition on.
- 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
- Turn the ignition off.
- 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.
- Disconnect the PCM C1 harness connector.
- Measure the resistance of the (K164) Fuel Temperature 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
- 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 .
- Measure the resistance of the (K917) Sensor Ground circuit between the Fuel Pressure harness connector and the PCM C1 harness connector.
