The P0605 diagnostic trouble code (DTC) for Dodge vehicles refers to a Control Module Fault. This code indicates that there is a malfunction within the vehicle's engine control module (ECM) or powertrain control module (PCM). The ECM/PCM is responsible for managing various functions within the engine, such as fuel injection, ignition timing, and emissions control. When this module is faulty, it can lead to a variety of performance issues and potentially cause the vehicle to stall or not start at all.

Cost to Fix P0605 Dodge

Typically, the cost of replacing a control module ranges from $500 to $1000, including parts and labor.

Tech Notes for P0605 Dodge
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).
