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


DESCRIPTION

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

DTC Code

  1. Diagnosis Condition
  2. Malfunction Status
  3. Malfunction Time
  4. Other
Trouble Area
P2767
  1. The vehicle is driven with the shift lever in D, the output shaft speed is 300 rpm or more and the vehicle speed is approx. 7 km/h (4.3 mph).
  2. The transmission revolution sensor (NIN) value is less than 300 rpm.
  3. 2 seconds
  4. 1 trip detection logic
  1. Open or short in transmission revolution sensor (NIN) circuit
  2. Transmission revolution sensor (NIN)
  3. 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 conclude that there is a malfunction in the primary pulley speed sensor. The ECM will illuminate the MIL and store the DTC.

INSPECTION PROCEDURE

1.READ VALUE USING INTELLIGENT TESTER (SPD (NIN))

  1. Connect the intelligent tester to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the intelligent tester on.

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

  1. In accordance with the display on the tester, read the Data List.

4.REPLACE ECM

  1. Replace the ECM (RAV4_ACA30 RM0000017UO01KX.html).

5.PERFORM INITIALIZATION
NOTICE:
  1. Performing reset memory will clear the learned values of both the yaw rate sensor assembly*1 or deceleration sensor*2 (deceleration sensor 0 point calibration) and CVT oil pressure (CVT oil pressure calibration). Make sure to perform reset memory, yaw rate sensor assembly*1 or deceleration sensor*2 0 point calibration and CVT oil pressure calibration when replacing any of the parts shown in the following table:
    Replaced Part
    1. Continuously variable transaxle assembly
    2. ECM
    3. Oil pressure sensor
    4. Yaw rate sensor assembly (w/ VSC)
    5. Deceleration sensor (w/o VSC)
    6. Brake actuator assembly (skid control ECU)
  2. After performing reset memory, always perform yaw rate sensor assembly*1 or deceleration sensor*2 (deceleration sensor 0 point) calibration first, and then CVT oil pressure calibration.
  3. Always perform 0 point calibration with the vehicle on level ground.
  4. Do not shake or vibrate the vehicle during 0 point calibration.

  1. Using the intelligent tester, perform reset memory, deceleration sensor 0 point calibration and CVT oil pressure calibration (RAV4_ACA30 RM000003UQR002X.html).

  1. Check that no DTC is stored.
