P077A: Understanding The Transmission Pressure Control Solenoid Circuit Low
The P077A fault code refers to a problem with the output speed sensor circuit in your vehicle. This sensor is responsible for detecting the revolution of the idler gear parking pawl lock gear and sending a pulse signal to the Transmission Control Module (TCM). The TCM then converts this signal into the vehicle’s speed.
However, in this case, the code indicates a loss of direction signal from the output speed sensor circuit.
When this fault code appears, it means that there is an issue with the circuit that transmits the direction signal from the output speed sensor.
This can result in inaccurate speed readings and potentially affect the overall performance of your vehicle.
It is important to address this issue promptly to ensure proper functioning of your vehicle’s transmission system.
