My check engine light keeps coming on and the code says a slow lt. forward O2 sensor. I changed the sensor 3 times but the light returns after about a day. Wassup?

 

I'm curious....

Did you replace the same part 3 times because you're a government worker, or are you a govenment worker because you're willing to replace the same part 3 times????

Sorry I can't help

 

nice guy

 

Could you give us some more info???

I am not sure what a slow It. forward O2 sensor refers to..

If you are having a problem with the O2 sensor..It does not have to mean that the sensor is bad...It could be that the sensor wire is pinched or grounded open etc..

Do you have two sets of O2's...what drive line do you have motor trans etc..what kind of truck, engine size, side that is affected..

Clogged converter, rich condition??? I am guessing..

 

Mine came on and it stayed on. I don't know what is up. It's running good
