The Input/Turbine Speed Sensor B Circuit is a crucial component in modern vehicles that monitors the speed of the transmission and the engine. This sensor provides essential data to the vehicle's engine control unit (ECU) to ensure optimal performance and efficiency. A malfunction in this circuit can lead to various issues related to transmission behavior.

What are the symptoms of the P2765 code?

Symptoms of a malfunctioning Input/Turbine Speed Sensor B Circuit may involve:

• Unusual transmission behavior, such as slippage or harsh shifting.
• Activation of the check engine light on the dashboard.
• Poor acceleration performance due to incorrect speed readings.
• Decreased fuel economy as the transmission fails to operate efficiently.

What causes the P2765 code?

Common causes of faults in the Input/Turbine Speed Sensor B Circuit include:

• Wiring issues such as frayed or damaged cables affecting signal delivery.
• Corrosion or poor connections at the sensor terminals.
• A faulty turbine speed sensor that fails to generate accurate readings.
• Software glitches or faults within the vehicle's ECU.

How to fix P2765?

To resolve issues with the Input/Turbine Speed Sensor B Circuit, consider the following steps:

• Inspect and repair any damaged wiring or connectors leading to the sensor.
• Replace the faulty turbine speed sensor if it does not respond correctly.
• Clear any diagnostic trouble codes and test drive the vehicle to see if the issue persists.
• If the problem remains, checking the ECU software for updates or reprogramming may be necessary.
