SPN100 FMI 2
CODES:
Fault Code: 435
PID(P), SID(S): P100
SPN: 100
FMI: 2/2
Lamp: AMBER
SRT:
REASON: Engine Oil Rifle Pressure - Data Erratic, Intermittent, or Incorrect. The engine oil pressure sensor is reading an erratic value at key ON.
EFFECT: None on performance. No engine protection for oil pressure.
Circuit Description:
The electronic control module (ECM) provides a 5 VDC supply to the engine oil pressure sensor on the sensor supply circuit. The ECM also provides a ground on the sensor return circuit. The engine oil pressure sensor provides a signal to the ECM on the engine oil pressure sensor signal circuit. This sensor signal voltage changes based on the pressure in the oil rifle. The ECM will detect a low signal voltage at operating conditions when the oil temperature is low.
Component Location:
The engine oil pressure sensor is located on the left side of the engine block.
Conditions for Running the Diagnostics:
This diagnostic runs when the keyswitch is turned ON and before engine speed is detected. The diagnostic only runs once per trip.
Conditions for Setting the Fault Codes:
The ECM detects that the engine oil pressure reading is higher or lower than the other absolute pressure sensors on the engine when the keyswitch is ON and the engine is not operating.
Action Taken When the Fault Code is Active:
• The ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails.
• A default value for the engine oil pressure reading is used.
Conditions for Clearing the Fault Code:
The ECM will turn off the amber CHECK ENGINE light immediately after the diagnostic runs and passes.
Shop Talk:
Verify the electronic control module (ECM) calibration is correct. Check the calibration revision history found on QuickServe® Online for applicable fixes to the calibration stored in the ECM. If necessary, calibrate the ECM.
At key ON, before the engine starts, the sensor readings for intake manifold pressure, exhaust gas pressure, engine air pressure, and engine oil pressure are compared to each other. This fault code occurs if the engine oil pressure sensor reading is different from the other sensor readings. This check is only done once after the keyswitch is turned ON.
Possible causes of this fault code include:
• Stuck in-range engine oil pressure sensor reading
• High resistance in the engine oil pressure sensor signal or return lines.
