Note from User:
P0605 Indicates that the programming for your transmission functions has become corrupted. In your 2008 Jeep, you should have one module (PCM) that controls the engine & transmission, and most likely needs to be replaced. If you have a individual TCM, it will be a little black box (a bit bigger then a credit card) under your dash on the DRIVER SIDE.
Note to some readers: If you are getting this code on an older vehicle (before 2003), especially Chrysler products, and you are getting this Code your TCM needs to be replaced. Flashing the TCM will not resolve this issue (maybe for 2 weeks at most). I say this because the info provided in the description of the Code is geared towards newer vehicles that use a PCM (or ECM as commonly referred to still).
To diagnose the P0605 Jeep code, it typically requires 1.0 hour of labor. The specific diagnosis time and labor rates at auto repair shops can differ based on factors such as the location, make and model of the vehicle, and even the engine type. It is common for most auto repair shops to charge between $75 and $150 per hour.
The Engine Control Module (ECM) continuously monitors its own internal memory status, internal circuits, and output signals transmitted to the throttle actuator. This self-check insures that the ECM is functioning properly. If any malfunction is detected, the ECM sets the P0605 code and illuminates the MIL.
