The transmission revolution sensor (NT) inputs the input shaft revolution speed to the transmission control computer ASSY as a signal.

The transmission control computer ASSY performs shift timing control based on signals from transmission revolution sensor (NT) and transmission revolution sensor (SP2).

P0716
  1. Engine RPM remains 400 RPM or higher for 2 seconds or more. With the shift position sensor in D position, a ratio of the vehicle speed determined from the output vehicle speed sensor to VDC vehicle speed is less than 5 %, and a ratio of the vehicle speed determined from the engine RPM and VDC wheel speed is less than 5 %. (2.5 seconds has elapsed after shift position has moved to D position. However, when the oil temperature sensor is faulty and the oil temperature is 20°C or lower, 10 seconds or more passed after shifting to D position).
  2. Ratio of vehicle speed determined from transmission revolution sensor (NT) to VDC wheel speed is more than 15 %.
  3. 10 seconds
  4. 1 trips
