In case you have not researched the fault code: DTC P0793, found in many Toyota vehicles, indicates a problem with the Intermediate Shaft Speed Sensor A circuit. This sensor measures the rotational speed of the intermediate shaft in the transmission and sends this data to the transmission control module (TCM) to help with gear selection. A P0793 code means the sensor is either not sending a signal, or the signal it's sending is not being recognized by the TCM.
Symptoms:
You might experience a check engine light, transmission issues (e.g., rough shifting, difficulty engaging gears), or increased fuel consumption.
Importance:
The intermediate shaft speed sensor plays a crucial role in controlling the transmission, and a faulty signal can lead to transmission damage or improper performance.
If it was mine I would not be driving long distances.
