Urgent--Replaced O2 Sensor But still have C.E.L..?
Car Details:
(94 Civic Coupe Ex)
(Stock B20b Swap)
(OBD1 P75 ECU)
(2.5 Inch Piping from Cat-Back)
Like The tiltle states....I've changed my Oxygen sensor 3 times in the past Month....(2 used) & (1 New) the New one being the Most recent & I still Have The Check Engine Light Code 41(Primary Oxygen Sensor Heater).
-i've reset the ECU everytime..
-checked wiring, its fine.
-made sure headers were screwed On tight.
- If Anyone Knows a Easy/Successful way to bypass/Trick the o2 sensor plz give me details cause I really want to get rid of this C.E.L asap.....

Thanx Man.
But I don't have a Multi Meter At this time.
And Instead of troubleshooting I kinda wanna jus bypass this so it doesn't reoccur in the future.
Anyone know Any Info Plz Let Me Know....

Go get a muti-meter. There cheap nowadays. Bypassing the O2 is bandaiding the problem, it's not going to fix it or make it better. The only way to "bypass" it anyway is to chip the ECU and tune it and disable the O2. If you didn't have this code until now, then I vote it lies in the wiring or ECU. You didn't use the original B20B harness did you?
