SPN 100 - FMI 2 (Fault Code: 435) B
SPN100 FMI2
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. An error in the engine oil pressure switch signal was detected by the ECM.
EFFECT: None on performance. No engine protection for oil pressure.
Circuit Description:
The engine oil pressure switch is used by the electronic control module (ECM) to monitor the lubricating oil pressure. If the oil pressure drops below the engine protection limit, the switch will open and cause Fault Code 435 to log. The oil pressure switch is normally closed when the engine is not running and open when oil pressure is present.
Component Location:
The engine oil pressure switch is located on the front of the engine on the left (intake) side on the top of the front gear housing.
Conditions for Running the Diagnostics:
This diagnostic runs continuously when the keyswitch is in the ON position.
Conditions for Setting the Fault Codes:
This fault code is logged when an open circuit is detected for five consecutive key cycles when the ECM expected a closed circuit at key-on.
Action Taken When the Fault Code is Active:
• The ECM illuminates the amber CHECK ENGINE light immediately when the diagnostic runs and fails.
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.
The oil pressure switch is closed with the engine not running and open when oil pressure is present. This fault code is logged when an open circuit is detected for five consecutive key cycles when the ECM expected a closed circuit at key ON.
Possible causes of this fault code include:
• Damaged engine oil pressure switch
• Open circuit in the engine oil pressure switch signal wire
• Damaged ECM
• Short circuit in the engine oil pressure switch signal wire to a voltage source.
