Is it advisable for me to replace the PCM myself. I see that you can purchase them online with them encoded with your VIN number. Is this a scam or is this a viable alternative to a very expensive dealership computer replacement?

Before replacing PCM, did you already rule out the following:
- Low battery voltage
- Faulty Alternator
- Engine cooling conditions that may set the code
- Engine coolant level
- Cooling system issues
- Ambient air temperature (AAT) sensor
- Engine coolant temperature (ECT) sensor
