if you have something dumb to say in this thread, hit the back button now please. do not flame in my thread!!


so i just bought my old car back after trading. well i got her back with 2 cel's one is 2 and the other is 21. now my questions are this.

when i had the car it only needed one o2 sensor, why am i getting a code for the secondary o2 sensor?? is there a way to bypass it even though my headers only have a bung for the primary o2? i am getting 150 on a half of tank of gas and im driving to miami from north carolina in a few weeks. i want the maximum fuel mileage.

the vtec solenoid problem (code 21) i am currently diagnosing as we speak. i tested it and it made the "click" noise when hooked up to a 12 volt power. the wiring is a little sketchy right now. i am going to re-wire the knock sensor, vtec pressure switch, vtec solenoid and secondary o2 sensor this wednesday. as they are desperately needing it.

any input or pictures would be great, thanks h-t

 

obd1 only has 1 O2 sensor (92-95) what ecu are you using, I might be wrong but thers no code 21 for obd1 cars. Are you running an obd2 ecu for the gsr? if so did you run the extra wire for the secondary O2 sensor?

 

ecu=pw0 and its obd0

 

any one
