CEL codes

[JDM onlyy]

I was wondering...I know that when it blinks fast it counts for the one's place digit and the longer lights counts for the tens place digit.

But I was wondering...I have one light that stays on long and blinks once..So does that count as one or ten? Cause if its one, then its the o2 sensor if its 10 then its the IAT sensor...

Help is much appreciated and will be repped for.

1 long means 10 fast blink means 1 so its 11 what kinda car, , 41 is O2 sensor,

[Tech5]

an 11 is not a code

[Tech5]

so try it again, an it will repeat itself,

no its just one long blink. Lol.

bad ecu

check the IAT out, an make sure you get .5 volts to the red/yellow wire, if so, then your sensor is bad, or you got a bad short to ground,

Unplug the sensor, and measure the resistance, between the two terminals, an is there , 0.4-4.0 if NO replace sensor, an disconnect your 7.5amp fuse in your fuse block next to the battery , for your radio, for 10-20 secs an plug it back in an road test, think this should help you , Joshua

No not bad ecu, until you can diagnosis that the ecu is bad, dont just replace parts b/c you think so, this can get someone fired at my shop if they dont know for sure, but sometimes, you have to take a gamble, not this one, since its not that big of a deal easy fix

Thank you, will do! :goodjob:

What would make you think its a bad ecu?

[Tech5]

He doesnt , just a Wild Guess,

[Tech5]

check my other, tech tips about checking the IAT out

[JDM onlyy]

I did, and I'll try those too. I think I might just swap it from my other manifold and see what happens. Lol

[Tech5]

its a simple test with a mutimeter, can get one at Autozone or wal-mart for less then 40 bucks, LMK if i can help Joshua

how did it go ?

how did it go ?

Fixed the IAT...I forgot when doing MPFI conversion you have an extra plug left over so I swapped the plugs and that turned it off. Now all I have is the dang TPS one, I changed the TPS and that didn't help it none...
