ok...95 ej coupe, jdm 2nd gen b16... idle is between 1500-2000rpm warmed up. i adjusted timing and idle screw with ecu connector jumped... then, even tho there is no cel on the gauge cluster, i checked just to be sure, and ecu is throwing code 7-tps and 14-iac , so, i think the sensors are just plugged in wrong... does that sound right?? there is also another sensor that hangs below the intake mani that goes to nothing...not sure what this sensor is for???

any help is appreciated...thnx

also, when u are adjusting the air idle screw on the TB, i know u jump the connector on the ecu, start car, warm up car, then unplug iacv, ...but what do u want the rpms to be set at with the iacv unplugged???

thnx

 

idle should be set to 400 with iacv unplugged. sounds like you have a sensor plugged incorrectly. if you are unsure about loose plugs you can use a multimeter to trace them back to the ecu

 

righton. thnx man! ive done swaps and im pretty savvy...just wanted to make sure the idle with iacv unplugged. im am pretty positive the sensors are swapped since they both fit the tps/iacv...i'll swap em around, adjust the idle and re-shoot the timing after work! i assume i should adjust idle before shooting the timing, correct?

 

This is a double post.

 

yea bc i posted more in detail information on this one... i need helping fixing this problem ...just dont wanna go spending unecasary money on parts i dont need if i dont have to...

 

OK..well...my other thread got deleted and im still having problems with my idle...i guess since it was a double post. sorry HT.
anyways, im gonna pull iacv off when i get home and clean it...see if that works, if not, i'll check the voltage at the ecu, but what pin is the tps???!!! guess i'll just try new tps/iacv and go from there... fml!

 

do not go buying new sensors until you are positive the wiring is correct. new sensors expensive and may not fix the problem if the wiring is junk.

sweet!!! thnx for the links!!! will post results...

 

Still waiting for results.

 

What colors are wires going to you TPS and IAT?
