P1704 Fault Code: Understanding The Description And Troubleshooting Tips
The P1704 fault code relates to the Transmission Control Module (TCM) in your vehicle.
The TCM is responsible for controlling the transmission solenoids and valves. It receives signals from various sensors, such as the Park & Neutral Position (PNP) Switch, Vehicle Speed Sensor (VSS), and Accelerator Pedal Position (APP) Sensor.
When the TCM’s memory Electrically Erasable Programmable Read Only Memory (EEPROM) malfunctions, it triggers the P1704 code. This code indicates that there is an issue with the TCM’s memory, which can affect the proper functioning of the transmission system. It is important to address this fault code promptly to ensure smooth and reliable transmission operation.
