DESCRIPTION:NOx inlet sensor failure to active.
MONITORED PARAMETER:NOx inlet sensor.
TYPICAL ENABLING CONDITIONS:NOx raw count.
MONITOR SEQUENCE:None
EXECUTION FREQUENCY:Continuous when enabling conditions met.
TYPICAL DURATION:Always on
DASH LAMPS:MIL
ENGINE REACTION:None
VERIFICATION:Once engine is at standard operating temperature, drive at highway speed with loaded trailer above 1130 rpm continuously for twenty minutes.
NOTE: If codes 5357-16 or 5357-18 present, fix those first.
PROBABLE CAUSES:1. Perform a stationary regen.2. SCR inlet NOx sensor.
