MULTI-MODE MANUAL TRANSAXLE SYSTEM, 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 vehicle running, the ECU interprets this as a malfunction in the transmission revolution sensor circuit. The ECU sets the DTC and illuminates the multi-mode manual transmission warning light.

DTC No. DTC Detection Condition Trouble Area
P0715

The TCM detects the following conditions simultaneously:

(1-trip detection logic)


  1. Vehicle speed is 14 km/h (8.7 mph) or more.

  2. Transmission revolution speed is 150 rpm or less for 4 seconds.

  • Open or short in transmission revolution sensor circuit

  • Transmission revolution sensor

  • TCM

PROCEDURE


  1. INSPECT SENSOR INSTALLATION (TRANSMISSION REVOLUTION SENSOR)


    1. A005K27E04
      Text In Illustration
      *a Normal
      *b Abnormal
      *c Clearance

      Check the transmission revolution sensor installation.

      OK
      Sensor is installed correctly.

    NG

    SECURELY INSTALL OR REPLACE SENSOR

    OK

  2. INSPECT TRANSMISSION REVOLUTION SENSOR

      *a

      Component without harness connected

      (transmission revolution sensor)

      Disconnect the B51 transmission revolution sensor connector.

    2. Measure the resistance between the terminals of the transmission revolution sensor connector.

      Standard Resistance
      Tester Connection Condition Specified Condition
      1 (NIP-) - 2 (NIP+) 20°C (68°F) 560 to 680 Ω

    NG

    OK

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


    1. Reconnect the B51 transmission revolution sensor connector.

    2. Disconnect the A47 TCM connector.

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

      Standard Resistance
      Tester Connection Condition Specified Condition
      A47-15 (NIP-) - A47-16 (NIP+) 20°C (68°F) 560 to 680 Ω
      A47-15 (NIP-) - Body ground Always 10 kΩ or higher
      A47-16 (NIP+) - Body ground Always 10 kΩ or higher

    NG

    REPAIR OR REPLACE HARNESS OR CONNECTOR

    OK
