In the back of the instrument panel, there is a small screw next to an empty hole. Remove the screw and put it in the empty hole. Repeat this every 90,000.

02 sensor light stays on after installing new one, now what?

The O2 sensor automatically comes on after so many miles, doesn't even have to be bad. You have to take the dash down and there is a tiny little screw that you need to move. The light will go out, but it will.still work. It's been awhile since I did this, but I believe it almost directly below it.

2002 toyota tacoma with a p1135 code and a # 4 cylinder misfire

I have had a problem like that on my Isuzu Rodeo Turns out the o2 sensor was bad. The computer reads it as not enough fuel. The mass airflow sensor will dump more fuel causing the engine miss fire.
You might check the codes again and see if you get the code for the 02 sensor. If so you can try to unplug the 02 sensor, the ck engine light will remain on, however the car should run without any issues.
Good Luck!!

1991 isuzu rodeo o2 dash light is stuck on

The O2 sensor needs to be replaced. There is a screw on the back side of the instrument panel that is removed and switched to another hole in the circuit board to reset the light for another 90,000 miles. Only a shop manual will have the exact location. You can try and obtain one from and buy one using print on demand.

Need to change O2 sensor check engine light wont go off

Did you change the 02 sensor? The back one after the converter? If so, stop by a dealer, it may need to be reset.The back 02 is the one that trips the light. Keep that in mind.

Cant find o2 sensors

if you follow your exhaust system you will find the o2 sensors they could have one right off the exhaust manifold and your second o2 is going to be behind the catalytic converter. so you will have a o2sensor before and after the catalytic converter on the exhaust hope this helps you out.
please rate me if you would
thank you

O2 sensor

There should be a reset switch that turns the light off. Some vehicles require a code scanner tool to reset the check engine light. On some Isuzu models you have to remove the instrument cluster and move a screw from one hole marked KSW to another hole with the same KSW marking (it may have tape over the second screw hole). Other Isuzu models may have a small switch on teh back of the instrument cluster or may have a different marking on the screw holes (some were marked wit the letter B on both holes). The O2 light usually comes on at 90,000 mile increments which is when Isuzu recommends changing it.
