DTC P2767: Input / Turbine Speed Sensor "B" Circuit No Signal [01/2019 - 11/2022]: Procedure
WARNING: This page is about a different car, the 2022 Toyota Corolla, 2021 Toyota Corolla, 2020 Toyota Corolla, and 2019 Toyota Corolla. However, it is still accessible from the selected car via links, so may be relevant.
- READ VALUE USING TECHSTREAM (SPD (NIN), ENGINE SPEED AND LOCK UP)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter the following menus: Powertrain / Engine and ECT / Data List.
- According to the display on the Techstream, 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 rpm680 to 780 rpm: Engine 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.: 65535 rpm- 0 rpm: Vehicle stopped
- 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
- Powertrain > Engine and ECT > Data List

- INSPECT TRANSMISSION REVOLUTION SENSOR (NIN)
- Disconnect the C74 transmission revolution sensor (NIN) connector.
*a Component without harness connected
(Transmission Revolution Sensor (NIN)) - Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition 1 (NIN-) - 2 (NIN+) 20°C (68°F) 560 to 680 Ω - Connect the C74 transmission revolution sensor (NIN) connector.
Result
Proceed to OK NG
Result:
NG
REPLACE TRANSMISSION REVOLUTION SENSOR (NIN). Refer to COMPONENTS [01/2019 - 03/2019] , or refer to COMPONENTS [03/2019 - 11/2022]
Result:
OK
See step 3
- Disconnect the C74 transmission revolution sensor (NIN) connector.
- CHECK HARNESS AND CONNECTOR (TRANSMISSION REVOLUTION SENSOR (NIN) - ECM)
- Disconnect the C77 ECM connector.
- Measure the resistance according to the value(s) in the table below.
Standard Resistance
Tester Connection Condition Specified Condition C77-123 (NIN+) - C77-124 (NIN-) 20°C (68°F) 560 to 680 Ω C77-123 (NIN+) - Body ground and other terminals Always 10 kΩ or higher C77-124 (NIN-) - Body ground and other terminals Always 10 kΩ or higher - Connect the C77 ECM connector.
Result
Proceed to OK NG
Result:
NG
REPAIR OR REPLACE HARNESS OR CONNECTOR (TRANSMISSION REVOLUTION SENSOR (NIN) - ECM)
Result:
OK
See step 4
- REPLACE ECM
- Replace the ECM.
