Description: Selective Catalyst Reduction Inlet Temperature – Not Plausible
Troubleshooting:
DESCRIPTION:
This fault sets if SCR Inlet temperature is 70°C (126°F) higher compared to all other
aftertreatment temperature sensors after 8-hour cold soak.
MONITORED PARAMETER:
Selective Catalyst Reduction (SCR) inlet temperature versus all other ATS temperature
sensors.
TYPICAL ENABLING CONDITIONS:
Engine off for more than 8 hours, battery voltage greater than 10.98 V, ignition on longer than
60 seconds.
MONITOR SEQUENCE:
Key on; engine off for more than 60 seconds.
EXECUTION FREQUENCEY:
Continuous when enabling conditions met.
TYPCIAL DURATION:
Two seconds
DASH LAMPS:
MIL
ENGINE REACTION:
None
VERIFICATION:
Ignition off / 8-hour cold soak.
POSSIBLE CAUSES:
1. SCR Inlet Temperature (high).
2. Spread pins.
3. Damaged pins.
4. Corroded pins.
5. Faulty SCR Inlet Temperature sensor.
