DTC P0715 INPUT/TURBINE SPEED SENSOR "A" CIRCUIT

CIRCUIT DESCRIPTION

DTC Detection Condition:

The input shaft revolution sensor is supplied in the gear box. It counts the gear input shaft revolutions and sends a signal to the transmission control ECU.

MONITOR DESCRIPTION

Monitor Strategy:

Typical Enabling Conditions:

Typical Malfunction Thresholds:

The input shaft revolution sensor detects the transmission input shaft speed. The transmission control ECU determines the gear shift timing based on a comparison of the input shaft revolution sensor (input shaft speed) with the vehicle speed sensor (wheel speed). When the vehicle speed is higher than the expected value and the input shaft speed is 200 rpm or less while shift lever is not in the "N" position, the transmission control ECU will conclude that there is malfunction of the input shaft revolution sensor (NIP). The transmission control ECU will illuminate the MIL and set a DTC.

INSPECTION PROCEDURE

HINT: Read freeze frame data using hand-held tester or OBD II scan tool, as freeze frame data records the engine conditions when a malfunction is detected. When troubleshooting, it is useful for determining whether the vehicle was running or stopped, the engine was warmed up or not, the air-fuel ratio was lean or rich, etc. at the time of the malfunction.
