Well I have read many codes but this one as of recent has me confused. Its one long blink, then 3-4 seconds, followed by another long beep. I figured this could be a code 10 correct? If it was code 20 the blinks would be closer together then 3-4 seconds correct? And If it was code 1 then they would not be long blinks but short. Any insight? thanks

 

damn no ecu gurus up in here.

 

One long blink and then a pause would be a code 10 yes sir!

Intake Air Temperature sensor (IAT)

 

thats what I thought. So I took it off, the sensor was not even dirty, but I wiped it off and inspected it anyway. It was not melted or broken or anything so I highly doubt that would be the problem. Today The ecu had a solid cel and went into limp mode not allowing me to go above 3k and I barely made it home. I really do not know what is up with this ecu.

 

Is it the stock ECU or is it chipped?
The IAT sensor is one of the main PGM-FI sensors that control how your car runs. It doesn't have to be dirty or show any signs of ware in order to stop working. Could be that the wire or connection has deteriorated.

Do you have a Helms or any other type of tech manual for your car?

 

ugh well I think I just got VERY lucky. I took the ecu covers off and noticed a very slight wetness around where the covers seal the board. Which leads me to believe the ecu got a tiny bit wet and started throwing codes for no reason. I unplugged it and dried it off and put it back in and no more check engine light,no more blinking ECU, and one very happy driver. Thanks for the help and DO NOT let leaky rubber groumets from the outside let water anywhere near your ecu.
