Integra CEL codes. ???

[DaRussian]

ok i got a 94 integra and its throwing 3 codes.
14 - IAC (EACV) - idle air control valve - changed it and its still on.
17 - VSS - speed sensor
41 - Primary oxygen sensor heater- i put in a new O2 sensor and its still on.

the idling sucks it keeps jumping up and down and after it works for about 10 min it dies.

anybody know what could be wrong? any help is appreciated.

Is the car stock?

there could be a number of things....

did you buy the car like that, did all 3 just appear. . like batlground said, is it stock? did you do a motor swap....ect.


you could have a vacuum leaks, hence it jumping around. o2 sensor could be a cut wire somewhere. . speed sensor may be bad, try changing it.

Ok here is a rundown, I have seen many people mix up plugs for IACV with many things. Make sure the plug you are using has a yel/blk and blk/blue wires on the plug. If it doesnt and you mixed it up, you may have fried some sensors.

Onto the VSS, MANY MANY times, when people swap engines the coolant from the heater hose, will drain into the vss upon removal of the engine. Check for corrosion, broken pins, or corroded, bad connector..

02 sensor, did you use a universal or a oem replacement?

a little more info on the setup, etc would help.

iacv code could be the reason it's not idling properly since it controls idle and low throttle airflow. there could be other reasons for the poor idle like vac leaks, timing jumped, etc.

Hey dude thanks for the help it solved one of the problems. the two plugs were swapped, i didnt even know that they were the same. it fixed the idle problem.

now i just need to figure out the O2 sensor. i bought the one that has one green wire one black and 2 white ones. but i was missing a plug from my engine harness. i looked at my friends b16 and connected it same way maybe they are different. Does anybody know the color of the wires for the O2 sensor?
