The P1824 fault code refers to the Internal Mode Switch ‘P’ Circuit Low Voltage.

This code is related to the Transmission Control Module (TCM) and indicates which gear position the driver has selected.

The internal mode switch consists of 5 separate hall effect switches, each supplied with a 9V reference circuit and a signal circuit from the TCM. The voltage readings on each internal mode switch circuit change depending on the gear selector position.

The P1824 code is triggered when the TCM detects that the internal mode switch ‘P’ signal circuit voltage is less than 0.7V for 1.75 seconds. This fault code can be diagnosed using a scan tool.
