Code P182E 2016 GMC Sierra Description

The park/neutral position switch and the 5 Hall Effect switches are internal to and part of the internal mode switch assembly. The park/neutral switch indicates to the engine control module (ECM) if the vehicle is in park/neutral or in a drive gear range. With the ignition ON, the ECM provides 12 V on the park/neutral signal to the park/neutral position switch. A separate ground wire from the park/neutral position switch to the Transmission Control Module (TCM) completes the path to ground. When the gear shift lever in park or neutral, the switch closes and drops the voltage on the signal circuit to 0 V. In this state the engine will start and run. In reverse or drive range the park/neutral switch opens, 12 V is then present on the signal circuit which will inhibit engine starting. The Diagnostic Trouble Code (DTC) will be set when the internal mode switch does not indicate a valid Park, Reverse, Neutral or Drive range gear position.
