Got CEL codes
 
My yearly smog is due and my car went to crud. The one is probably due to low gas for the last couple months, need to fill and see if it goes away.
The other failure, that's the fun one. I reflashed back to stock to see if that helped. Nope, didn't work. Can't even drive the car as it won't rev past 1800 rpm

Anyone have info on this P0605 code

karlt 01-10-2019 12:23 PM
According to my MY2005 Service Manual, DTC P0605 can occur for three reasons: 1) ECM calculation function is malfunctioning, 2) ECM EEPROM system is malfunctioning, or 3) ECM self shut-off function is malfunctioning. Failure 1) causes the system to go into fail-safe, or limp, mode, which is what you're seeing. For any of the listed faults, the only correction listed in the Service Manual is to replace the ECM.

Replace ECU , great.

Is there any way you can completely wipe the ecu? I know coming from a computer guy standpoint that a clean wipe usually puts all the memory back to like it was out of the box.

so I found a rebuild service. They test, fix and reset the ECU for $100

i flashed mine back to stock, removed the tune completely hoping it was my tune that got corrupted.

Better than a whole new ECU.

In theory, no reprogramming required.

Sent the ECU off for rebuild, the processed is bad and they are sending it back. I need to replace the ECU, guess I need to find an ECU in the junkyard. Guess I’ll have to tow it to the dealer for programming

Flash it with Uprev to bypass NATS

I’ll have to do that, was planning on selling my cable as it’s all been removed from my car.

Easier and cheaper than towing to the dealership for a reprogram :) Let me know if you need another license
