P1821 Fault Code: Transmission Gear Lever Position Sensor Circuit Malfunction
The P1821 fault code is related to the Shift Fork Position Sensor 1 in the Transmission Control Module (TCM). This sensor is responsible for monitoring the position of the shift fork.
When the TCM detects that the Shift Fork Position Sensor 1 is not within the factory specifications, it triggers the P1821 code.
The P1821 code specifically indicates that the system voltage for the Shift Fork Position Sensor 1 is too high. This means that there is an issue with the electrical voltage being supplied to the sensor. When this fault code is present, it is important to have the sensor and its electrical connections inspected and tested.
If necessary, the sensor may need to be replaced or the electrical wiring repaired to resolve the high voltage issue. It is recommended to address this issue promptly to prevent any further damage to the transmission system.
FAQ
