СИСТЕМА МЕХАНИЧЕСКОЙ ТРАНСМИССИИ "MULTIMODE", Diagnostic DTC:P0715

DTC Code DTC Name
P0715 Input / Turbine Speed Sensor Circuit Malfunction

DESCRIPTION

The transmission revolution sensor is mounted on the transaxle. The TCM calculates the transaxle input shaft speed using the sensor. When the input shaft rotates, the sensor generates a pulse signal and sends the signal to the TCM. The ECU calculates the input shaft speed based on the signal. If the input shaft speed falls below a threshold despite the engine running, the ECU interprets this as a malfunction in the transmission revolution sensor circuit. The ECU stores this DTC and illuminates the multi-mode manual transaxle warning light.

PROCEDURE

  1. INSPECT SENSOR INSTALLATION (TRANSMISSION REVOLUTION SENSOR)

    1. Check the transmission revolution sensor installation.

      A012HTJC02
      *a Normal
      *b Abnormal
      *c Clearance
      OK
      Sensor is installed correctly.

      Proceed to
      OK
      NG
    NG

    SECURELY INSTALL OR REPLACE SENSOR


    OK
  2. INSPECT TRANSMISSION REVOLUTION SENSOR

    1. Disconnect the transmission revolution sensor connector.

  3. CHECK HARNESS AND CONNECTOR (TRANSMISSION REVOLUTION SENSOR - TCM)

    1. Reconnect the transmission revolution sensor connector.

    2. Disconnect the TCM connector.

    3. Measure the resistance according to the value(s) in the table below.

      Standard Resistance
      Tester Connection Condition Specified Condition
      A108-15 (NIP-) - A108-16 (NIP+) 20°C (68°F) 560 to 680 Ω
      A108-15 (NIP-) - Body ground Always 10 kΩ or higher
      A108-16 (NIP+) - Body ground Always 10 kΩ or higher
      Result
