Laymans terms

This code means that the car's computer has detected a problem with the sensor that measures the pressure of the transmission fluid. It's like a thermometer that isn't working right, so the car doesn't know how hot it is.

Explanation

The P083C code is triggered when the Transmission Control Module (TCM) detects a low voltage signal from the transmission fluid pressure sensor/switch G. This indicates a possible issue with the sensor or its circuit.

Technical description

The transmission fluid pressure sensor/switch G is responsible for monitoring the pressure of the transmission fluid in the vehicle. This sensor sends a voltage signal to the TCM, which uses this data to ensure the transmission operates correctly. A 'circuit low' condition typically means the sensor is sending a lower than expected voltage, indicating a potential fault in the sensor, wiring, or connections.

Symptoms

• Check Engine Light is on

• Transmission may not shift properly

• Poor fuel economy

Common Causes

• Faulty transmission fluid pressure sensor/switch G

• Damaged or corroded wiring or connectors

• Faulty TCM
