RENR5042-02 65 Troubleshooting Section Results: All of the above conditions occur simultaneously for at least 30 seconds. OK STOP. System Response: i02281075 CID 0102 FMI 04 Boost Pressure Sensor short to ground The ECM will log the diagnostic code. The diagnostic code may be viewed on the electronic service tool. The ECM will flag the boost pressure as invalid data. The value of the boost pressure is set to a default value. SMCS Code: 1917-038 Possible Performance Effect: Conditions Which Generate This Code: Engine performance is adversely affected. The signal voltage from the boost pressure sensor is below 0.2 VDC for at least two seconds. Troubleshooting:
Perform the following diagnostic procedure: Volt Engine Pressure Sensor Supply Circuit - Test” System Response: The Electronic Control Module (ECM) will log the diagnostic code. The ECM will flag the boost pressure as invalid data and a default value is used for the boost pressure. Results: OK STOP. Possible Performance Effect: i02214851 CID 0110 FMI 03 Engine Coolant Temperature open/short to +batt Low power Troubleshooting: Perform the following diagnostic procedure: “Engine Pressure Sensor Open or Short Circuit - Test” SMCS Code: 1906-038 Conditions Which Generate This Code: Results: The Electronic Control Module (ECM) detects the following conditions: OK STOP.
The engine has been running for more than seven minutes. i02214842 CID 0102 FMI 10 Boost Pressure Sensor abnormal rate of change The signal voltage from the engine coolant temperature sensor is greater than 4.95 VDC for more than eight seconds. SMCS Code: 1917-038 System Response: Conditions Which Generate This Code: The ECM will log the diagnostic code if the engine has been running for more than seven minutes. The check engine lamp will illuminate after a delay. This diagnostic code is designed to detect the loss of the 5 volt supply at the sensor connector. The ECM will set the value of the coolant temperature to a default value.
The Electronic Control Module (ECM) detects all of the following conditions: The engine will not go into cold mode while this diagnostic code is active. The engine speed is greater than 1000 rpm. The signal from the boost pressure sensor is within the acceptable range. The ECM will activate the cooling fan after this code has been active for more than eight seconds. The signal from the boost pressure sensor remains abnormally constant.
