Default The long awaited codes...

Here are the codes I pulled today. Not too sure if I read them right or not but I'm sure if I did then someone will point it out to me.

12, 21, 22, 15, 12, 52.

I ran them like three times to make sure I was doing it right and these are the numbers that repeated when tried again.

Looks more like a Lotto ticket!
12 RPM high or low at idle. That's a R code.
21 ECT sensor out of range...........If your not going to buy the $22. code reader, Read & follow this carefully:

You must preheat the engine to normal operating temp before both tests. & review how the power steering & WOT test is done, during the KOER test.

But to begin w/, bring the engine to operating temp. then shut off & do the Key on engine off (KOEO) & report the results for that scan only first. Those results need to be delt w/ before moving on to the KOER scan.

The engine was preheated. I parked it after driving for 10-15 miles, had things to do. That's what I came up with. I didn't know anything about a WOT test or a power steering test either.
