The P2767 fault code indicates a problem with the Input/Turbine Speed Sensor B Circuit. This specific code signifies that there is no signal being received from the sensor, which is crucial for proper transmission operation. The sensor measures the rotational speed of the turbine or input shaft to assist in the correct shifting of gears.

What are the symptoms of the P2767 code?

Symptoms associated with the P2767 fault code may include:

• Harsh or erratic shifting of gears.
• Slipping transmission.
• Unresponsive or delayed transmission behavior.
• Check Engine Light illuminated on the dashboard.

What causes the P2767 code?

There are several potential causes for the P2767 code, including:

• A faulty Input/Turbine Speed Sensor B.
• Damaged wiring or connectors in the sensor circuit.
• A faulty Transmission Control Module (TCM).
• Issues related to the transmission fluid, such as low levels or contamination.

How to fix P2767?

To resolve the P2767 code, consider the following steps:

• Inspect and, if necessary, replace the Input/Turbine Speed Sensor B.
• Check all wiring and connectors for signs of damage or corrosion; repair or replace as needed.
• Ensure that the transmission fluid level is correct and that the fluid is clean. Change the fluid if it’s contaminated.
• If the problem persists, a diagnostic test of the Transmission Control Module (TCM) may be required to check for faults.
