CONTINUOUSLY VARIABLE TRANSAXLE SYSTEM, Diagnostic DTC:P2767

DTC Code DTC Name
P2767 Input / Turbine Speed Sensor "B" Circuit No Signal

DESCRIPTION

The ECM detects the input shaft speed based on the signal from the transmission revolution sensor (NIN) and performs gear ratio control.

  1. Driving with shift lever in D and output shaft speed 300 rpm or more (vehicle speed is approximately 7 km/h (4 mph) or more).

  2. The speed indicated by the transmission revolution sensor (NIN) is less than 300 rpm.

  • Harness or connector

  • Transmission revolution sensor (NIN)

  • ECM

Comes on DTC stored

MONITOR DESCRIPTION

The ECM receives a signal from the 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 transmission revolution sensor (NIN) even while the vehicle is moving, it will determine that there is a malfunction in the transmission revolution sensor (NIN). 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 engine switch on (IG).

    3. Turn the GTS on.

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

    5. In accordance with the display on the GTS, read the Data List.


      Powertrain > Engine and ECT > Data List
      Tester Display Measurement Item Range Normal Condition Diagnostic Note
      Engine Speed Engine speed

      Min.: 0 rpm

      Max.: 16383 rpm

      710 to 810 rpm: Idling When the crankshaft position sensor is malfunctioning, "Engine Speed" is approximately 0 rpm or varies greatly from the actual engine speed.
      SPD (NIN) 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.
      Lock Up Lock-up OFF or ON
      • ON: Lock-up operating

      • OFF: Lock-up not operating
