allright guys i gotta code 14 and 10,which are IAC and IAT sensors can someone help me out on the location and how to fix em'
thanks in advance

 

oh woops its on a D15B2/D16Y7 head and sadly i still have DPFI.....havent done the MPFI swap yet.....

 

I'm getting the same codes. I change out the eacv and the iat, reset ecu and still getting those 2 codes. The iac and the iat is located on the drivers side on the intake manifold. the iat is on the #3 intake runner that has two phillips head screws holding it down. The iac (eacv) has 2 12 mm bolts holding it down. Also has couple of vac hoses connected to it. hope this helps

 

oh really me too , i think maybe the sensors are bad, one of them is on the intake manifold all the way to the fourth tube,but your saying u actually changed them.....well im gonna keep trying and post up

 

Ya, they are both brand new from the auto parts store. If you need pics, I can get you some.

 

please dude that will help,thanks a lot nemisis8nt@aim.com

 

quick QUESTION, i just recently put a d16y7 HMT setup in my car and i got a code 10 on my ecu and i was geting a high rpm idel like a surge up and down. now i changed the tb from a b18a1 to a z6 tb which ii converted the intake manifold over to a z6 mani for the dp-mpfi. neways does your car have a idel surge or whtever. bc if u changed them and their new maybe mine arnt bad? give me some info please also how much them sensors coasted ya. thanks

 

Maybe you switched the plugs. The one for the IAC was plugged in the IAT and vise versa. The one for the IAT should be a red/white wire and a green/white wire. I believe the colors for the IAC are one black wire and a blue wire with a stripe, but i fogot what the color of the stripe.


Switch the plugs or verify the colors of the plugs.

 

Well I had the plugs switched. I got rid of code 14,b but I am still getting 10. I'll just get another iat sensor.

 

u switched the plugs and got rid of code 14 IAC?

 

Ya, because I had the plugs switched. So I guess having those switched, It messed up the IAT sensor.

 

No more codes for me.

 

the IAC plug can be swapped with another sensor, dont' remember which and will make your car act all funny in time.

IAT is simple enough and can be had from the wreckers for like $10 and grab a couple, or a new one if you wish.

Either way good idea to replace it.

 

Matter of fact I just went to the junk yard about 30 minutes ago and got a IAT sensor off another car. No more code 10 for me.

 

yea they were wrong,i switched them and now for sum reason i dont idle at higher RPMS anymore,still got the same codes,i even re-flashed the ECU,sensors have to be bad

 

You mean reset the ecu. Pulling the hazard fuse out for 10 seconds. I pulled the ecu and the hazard fuse out for about a minute then put them back in. So ya, if you switched the plugs to where they go and you are still getting the codes then they are bad. Both of those are expensive brand new. I'd suggest going to a junkyard to get them.

 

Make sure the plugs are in the correct sensor.

If they are, then the next step is to get a multimeter and check for voltage and ground.
On the IAT sensor, the red/white wire should be getting 5 volts with the car on the ON POSITION and the car not running. Just unplug the sensor and check it. The green/white wire should be ground. You can try and put the two leads in the sensor and you should read 5 volts. If you dont get that, then try each one separtely. Try the red/white and a body ground or the battery negative and then try the battery positive and the green/white, this should give you 12 volts.

On the IACV, i believe its the same thing. The black/yellow wire should be 5 volts and the blue wire should be ground.

 

thanks dude good info

 

Have you got it figured out yet?

 

yea overall sensors were good but i looked underneath the IM and the ground wasnt plugged
lol

 

That's good.
