Code P0706 Jeep Description

The signal circuits communicate the shift lever position to the Powertrain Control Module (PCM). Each circuit is terminated at the transmission with a switch. Each switch can be either open or closed, depending on the shift lever position. The PCM can decode this information and determine the shift lever position. Each shift lever position has a certain combination of switch positions (open or closed), this is called a PRNDL code. There are 4 switches, therefore: there are many possible combinations of open and closed switches (codes). However, there are only 9 valid codes (8 for AutoStick), one for each gear position, and three recognized between gear (transition) codes. Any other switch combinations should never occur, these are called invalid codes. The Diagnostic Trouble Code (DTC) will set if an invalid PRNDL code exists for more than 100 milliseconds within one second of power-up or if the PRNDL code error does not correct itself when (or before) the shift lever is moved to a different position (P, R, N, or OD), or if the PCM sees the PRNDL code rapidly (within 7 ms) jump across more than 3 shift lever detent positions.
