Input / Turbine Speed Sensor "B" Circuit No Signal

  1. Diagnosis Condition

    • The vehicle is being driven with the shift lever in D and the output shaft speed is 300 rpm or more.

  3. Malfunction Status

    • Transmission revolution sensor (NIN) value is less than 300 rpm

  5. Malfunction Time

    • 2 seconds

  7. Other

    • 1-trip detection logic

  • Wire harness or connector

  • Transmission revolution sensor (NIN)

  • ECM

MONITOR DESCRIPTION

The ECM receives a signal from the primary pulley speed sensor (transmission revolution sensor (NIN)) installed in the continuously variable transaxle and determines the input shaft speed in order to control the gear ratio. If the ECM detects no signal from the primary pulley speed sensor even while the vehicle is moving, it will determine that there is a malfunction in the primary pulley speed sensor. The ECM will illuminate the MIL and store this DTC.

PROCEDURE

  1. READ VALUE USING GTS (SPD (NIN), ENGINE SPEED AND LOCK UP)

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary.

    5. According to the display on the GTS, read the Data List.

      Engine Speed

      Engine speed

      min.: 0 rpm

      max.: 16383 rpm

      600 to 700 rpm: Idling

      When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.

      Primary pulley speed (NIN)

      min.: 0 rpm

      max.: 12750 rpm

      • 0 rpm: Vehicle stopped

      • Primary pulley speed (NIN) equal to engine speed(NE): Lock-up ON (After warming up engine)

      Data is displayed in increments of 50 rpm.
