check engine

[stang2009]

I had my check engine light come on the other day, so i had the codes pulled and it came up as a p1131 code. I figured out that it could be many things. My only real question is that the other day the light went off. Last time i took my car in it did the same thing, the guy told me the car stores the code and there could still be a problem. Well do i really need to take my car in if the light went off? The car runs fine, so i dont want to have to pay for nothing.

P1131 Lack of Upstream Heated Oxygen Sensor Switch - Sensor Indicates Lean - Bank No. 1.

I would try replacing the front driver side ( i think thats bank 1 ) oxygen sensor .

THANKS I wasnt sure

I didn't know for the longest time. I had to find out once I had an 02 sensor problem. It would make sense that they would make the drivers side bank 1, but I guess someone didn't think so. Go figure.

Do I need to replace it, b/c the light went off yesterday and hasn't come back on. thanks

 

[2002BLGT]

if it doesnt come back on , dont worry about it , if it does and pulls the same code again , then replace it .

Hey Guys, I need some help with two codes, P1443 & P1507. Check Engine Light came on yesterday and today car would not stay idle for like 20 minutes.

Hey one more question, is there a way to test the o2 sensors, besides taking them into a dealership. thanks for all the help

You can get a software like Autotap and it will should let you know if your sensors are actually working. If not then you can get a haynes manual, and they have a procedure for checking them. Better to spend $20 to do it yourself than $80 at Ford.
