Theory of Operation
The Park Neutral switch rationality test is enabled only for vehicles equipped with a 4/5 speed automatic transmis-
sion. This diagnostic checks if the park/neutral switch is incorrectly stuck in the neutral position during driving con-
ditions by comparing Vehicle Speed, Engine Speed, Throttle Position, andPressure Ratio to the fail thresholds and
by looking at the state of the Park/Neutral Switch. The stuck in drive condition is not explicitly checked as the starter
relay does not energize and therefore render the vehicle inoperable.
When Monitored:
Continuously with the transmission in Park, Neutral, or Drive and NOT in Limp-in mode.
Set Condition:
This code will set if the PCM detects an incorrect Park/Neutral switch state for a given mode of vehicle oper-
ation. One trip fault. Three good trips to turn off the MIL.
Possible Causes
TRS (T41) SENSE (P/N SENSE) CIRCUIT OPEN
TRS (T41) SENSE (P/N SENSE) CIRCUIT SHORTED TO GROUND
TRANSMISSION RANGE SENSOR
