Intermediate Shaft Speed Sensor "B" Circuit Short to Battery (P274512,P274514,P274531)
DESCRIPTION
The transmission revolution sensor (NC1) detects the intermediate shaft (C1 clutch)
speed and sends it to the TCM.
The TCM determines if gear mode should be entered by comparing the transmission
revolution sensor (NT) and (NC1) signals.
DTC No.
