P2767 OBD-II Trouble Code: Input/Turbine Speed Sensor B Circuit No Signal

check engine light

P2767 Code Definition

The P2767 code is a generic powertrain code related to the transmission or gearbox. In particular, it states that the engine control module (ECM) is receiving incorrect information from the input/turbine speed sensor B.

Codes related to the P2767 include:

  • P2765: Input/Turbine Speed Sensor “B” Circuit
  • P2766: Input/Turbine Speed Sensor “B” Circuit Range/Performance
  • P2768: Input/Turbine Speed Sensor B Circuit Intermittent
  • P2784: Input/Turbine Speed Sensor A/B Correlation

What the P2767 Code Means

The ECM receives signal inputs from the engine speed sensor, which it translates to the transmission to help it shift correctly. When a P2767 code is stored, it means the system has multiple input speed sensors and it is specifying an issue with sensor B, particularly that no signal is being received at all. The vehicle’s service manual can confirm the location of this particular sensor.

A vehicle’s ECM expects input speed to gradually increase and not exceed the output speed. At this point, a shift point is reached. When the ECM receives no signal from input sensor B, a P2767 code will be stored.

What Causes the P2767 Code?

Several problems may cause a P2767 code including:

What are the Symptoms of the P2767 Code?

Symptoms of a P2767 code may include:

How Does a Mechanic Diagnose the P2767 Code?

A mechanic may use several methods to diagnose a P2767 trouble code, including:

  • Utilize an OBD-II scanner to check for a stored P2767 trouble code
  • Visually inspect all wires and connectors for possible damage
  • Check voltage and ground signals at input speed sensor
  • Check for continuity and resistance in both voltage and ground circuits
  • Check for damaged or defective shift solenoid
  • Test for damaged or defective engine temperature sensor

Common Mistakes when Diagnosing the P2767 Code

One common mistake noted when diagnosing a stored P2767 code includes believing it is a vehicle speed malfunction and the replacement of vehicle speed sensors.

How Serious is the P2767 Code?

Because a vehicle’s safe driving operation may be impacted due to faults that store a P2767 code, this code is considered a potentially serious code. When this code appears, it is recommended to immediately take your vehicle to your local service center or mechanic for repair and diagnosis.

What Repairs can Fix the P2767 Code?

Several repairs can fix a P2767 trouble code and include:

  • Repair or replace any damaged or corroded wiring and connectors
  • Flush and fill transmission fluid
  • Repair or replace damaged or defective input speed sensor circuits and connectors
  • Repair or replace damaged or defective output speed sensor circuits and connectors
  • Repair or replace damaged or defective shift solenoid
  • Repair or replace damaged or defective engine temperature sensor
  • Repair or replace any damaged or defective system circuits, components, and wiring
  • Clear all codes, test-drive the vehicle, and rescan to see if any codes reappear

Additional Comments for Consideration Regarding the P2767 Code

Some vehicles may require multiple failures before a check engine or warning light is illuminated. When a P2767 code is stored, vehicle owners should be aware that this may not be due to the first occurrence of the problem. In addition, an output speed sensor code will frequently accompany a P2767 code.
