DTC P0726: Range/Performance Problem in Engine RPM Signal Input Circuit: General Description
The transmission control module (TCM) converts the engine ignition signal into the engine speed signal. The CVT input shaft (drive pulley) speed sensor detects the number of revolutions of the gear on the drive pulley and outputs a pulsing signal to the TCM. The TCM converts the pulsing signal into the drive pulley speed. If the engine speed is lower than an estimated value based on the drive pulley speed when the shift lever is in D, L, or R, a malfunction is detected and a DTC is stored.
