Hi-

I just finished replacing the downstream O2 sensor closet to the firewall (Bank 1 sensor 2) to clear a "check engine" code. It took me a week to get the part (long story) and I used a Denso 234-4368.

I go everything back together with no issues. When I turned the key, the instrument panel started blinking! The "check engine" light is off (moral victory!). But the "brake" light is now on permanently, as are the "Airbag" and "VSA" lights. I did a quick check inside the engine compartment and couldn't find anything that was unplugged.

Any ideas would be greatly appreciated!

 

Update: the "ABS" (not the "airbag") light is on and none of the instruments function when I drive: speedometer, tach, fuel, temperature.

 

Check the fuses first. Sounds like one or two have blown.

 

Hey Poorman212-

I pulled every damn fuse. They were all good! But, fearing further trouble from my
incompetence, I disconnected the battery before starting the excercise. When I finished sampling the fuses, I reconnected the battery and all the problems went away! I guess the computer just needed to be reset?

Anyway, thanks for helping me solve the problem and avoiding the dealership jackals!

 

Hey, glad it was a simple fix???? Thanks for the update
