so first off..the car is a 89 crx HF with a obd0 b16 swap. i did a search and i found the info on the faq about getting a resistor and plugging it in to see if the problem is with the sensor or the wiring. well i got the resistor (330 ohm 1/2 watt spec, or one from Radio Shack part# 271-1113) and i still get a cel and bad idle.

i also have the factory service manual for the crx and i went through the process of testing with a multimeter. and the wiring seems to be alright. i get 5v's on the red wire and i get 5v's between both ect wires. i finally broke down and bought a new ect and tried that....still getting a cel!!!!

one thing that did turn the cel off was when i restarted the car after it was already warmed up...i guess because the car doesn't look at the ect after its warm? i'm not sure. can anyone help??

 

help!

 

weird....today im sitting at a redlight and the cel goes off and idle goes to back to normal. weird? i gotta go drive around some more to see if its still off...i duno whats goin on with it.

 

u check ur codes?? sounds like a bad iacv.

 

it's a code 6. ect. but so far it seems like it might be fixed. it turned off today and hasnt come back on....weird

 

alright. so i let the car cool down completely and then started it up and drove around and the cel came on instantly. then when the car was warmed up.....it went off. what the hell? anyone know whats goin on here? the sensor is brand new
