RENR5042-02 63 Troubleshooting Section Troubleshooting: System Response: Perform the following diagnostic procedure: “Throttle Position Sensor Circuit - Test” The Electronic Control Module (ECM) will log the diagnostic code. The ECM flags fuel pressure as invalid data and a default value of 600 kPa (88 psi) is used. Results: OK STOP. Perform the following diagnostic procedure: “Engine Pressure Sensor Open or Short Circuit - Test” i02258069 CID 0091 FMI 13 Throttle Position calibration required Results: OK STOP. SMCS Code: 1913-038 i02286373 CID 0094 FMI 04 Fuel Pressure short to ground Conditions Which Generate This Code:
The duty cycle of the signal from the throttle that is connected to the primary throttle input is incorrect. SMCS Code: 1718-038 System Response: Conditions Which Generate This Code: The Electronic Control Module (ECM) will log the diagnostic code. The ECM flags the throttle position as invalid data and a default value of zero percent is used. The signal voltage from the fuel pressure sensor is below 0.1 VDC for at least eight seconds. System Response: Possible Performance Effect: The Electronic Control Module (ECM) will log the diagnostic code. The ECM flags fuel pressure as invalid data and a default value of 600 kPa (88 psi) is used. The engine speed is limited to low idle.
Troubleshooting: Perform the following diagnostic procedure: “Throttle Position Sensor - Calibrate” Perform the following diagnostic procedure: “Engine Pressure Sensor Open or Short Circuit - Test” Results: Results: OK STOP. OK STOP. i02281072 CID 0100 FMI 03 Engine Oil Pressure open/short to +batt i02286369 CID 0094 FMI 03 Fuel Pressure open/short to +batt SMCS Code: 1718-038 SMCS Code: 1924-038 Conditions Which Generate This Code: Conditions Which Generate This Code: The signal voltage from the fuel pressure sensor is above 4.95 VDC for eight seconds. The signal voltage from the engine oil pressure sensor is above 4.95 VDC for at least eight seconds. System Response:
The Electronic Control Module (ECM) will log the diagnostic code. The ECM flags oil pressure as invalid data and a default value of 600 kPa (88 psi) is used. Perform the following diagnostic procedure: “Engine Pressure Sensor Open or Short Circuit - Test”
