U660F AUTOMATIC TRANSMISSION / TRANSAXLE: AUTOMATIC TRANSAXLE SYSTEM: P0500: Vehicle Speed Sensor "A"
P0500 - Vehicle Speed Sensor "A"
DESCRIPTION
The speed sensors detect the wheel speed and send the appropriate signals to the skid control ECU. The skid control ECU converts these wheel
speed signals into a 4-pulse signal and outputs it to the TCM via the combination meter. The TCM determines the vehicle speed based on the
frequency of these pulse signals.
MONITOR DESCRIPTION
The TCM assumes that the vehicle is being driven when the transmission counter gear indicates more than 300 rpm and over 30 seconds have passed
since the park/neutral position switch was turned off. If there is no vehicle speed signal with these conditions satisfied, the TCM concludes that there
is a vehicle speed signal malfunction. The TCM will turn on the MIL and a DTC will be set.
