TCM

DTCP1816
Circuit / System Description
The automatic transmission fluid pressure (TFP) manual valve position switch consists of 5?pressure switches, 2?normally-closed and 3?normally-open, and a transmission fluid temperature (TFT) sensor combined into 1?unit. The combined unit mounts on the valve body. The transmission control module (TCM) supplies ignition voltage for each range signal. By grounding 1?or more of these circuits through various combinations of the pressure switches, the TCM detects which manual valve position you select. The TCM compares the actual voltage combination of the switches to a TFP manual valve position switch combination chart stored in memory.
The TFP manual valve position switch cannot distinguish between PARK and NEUTRAL because the monitored valve body pressures are identical. With the engine OFF and the ignition switch in the ON position, the TFP manual valve position switch indicates PARK/NEUTRAL. Disconnecting the AT inline 20-way connector removes the ground potential for the 3?range signals to the TCM. In this case, with the engine OFF, and the ignition switch in the ON position, D2 will be indicated.
When the TCM detects an invalid state of the TFP manual valve position switch circuit by deciphering the TFP manual valve position switch inputs, then DTC?P1816 sets. DTC?P1816 is a type?B DTC
