OBD Code P0606

ECM/PCM Processor

What’s mean?

OBD2 Code P0606 Definition:
This code is a fairly simple one. It basically means that the PCM/ECM (powertrain/engine control module) has detected an internal integrity fault in the PCM. When this code is activated it should store freeze-frame data that helps someone with an advanced code scanning tool to get information on exactly what was going on with the vehicle when the P0606 code was triggered.

Symptoms

Possible sumptoms of P0606
Most likely the only symptom of a P0606 DTC code is the illumination of the “Check Engine Light” a.k.a. MIL (Malfunction Indicator Lamp).

Possible Causes

Possible causes of P0606
In all likelyhood the PCM / ECM has failed.

Possible Solutions

As a vehicle owner there is little you can do to fix this code. The most common fix for a P0606 code is to replace the PCM, although in some cases re-flashing the PCM with updated software could possibly fix this. Be sure to check for TSB’s on your vehicle (Technical Service Bulletins). In all likelyhood the fix is to replace the PCM. This is generally not a “do-it-yourself” task, although in some cases it may be. We strongly recommend you have a qualified repair shop / technician do the work, one that has the capability to reprogram the new PCM. Installing the new PCM may involve using special tools to program the vehicle’s VIN (vehicle identification number) and/or anti-theft information (PATS, etc.). NOTE: This repair may be covered under the emissions warranty so be sure to check with your dealer as this may be covered beyond the bumper-to-bumper or powertrain warranty period.
