check eng light
 

I know this going to get a lot of we need codes, but I have not had time to go by auto zone. But the check eng light come and goes with the out side temp any ideas to the cause. If the temp is be low 45 deg the light come on get above that and it gone. The only thing i have done to the eng was replace O2 sen with the last check eng light came on. That was about 30 days ago ?
:cowboy:

Best to come back here AFTER you go to Autozone and get the codes read. Any guess without the codes would be just that......a guess.

(a no code wild guess..bad thermostat)

We're that predictable huh? But you nailed it, no codes, no useful help, just guesses.

My thought are the same as George's. Using the SWAG principle, at first blush it sounds like a duff thermostat, but post up the codes when you can.

With the correlation being spotted between the temperature and the CEL coming on, it sounds like you have been dealing with it for a while?

What was the code related to the O2 sensor replacement?

My guess is that it has arthritis and hates temps below 45F like me.

:lol: I agree with George though.

However if it is the thermostat jammed open, making it slow to warm up, not only does it throw a code, typically the temperature gauge quits working, the digital temp goes to "----" and the A/C stops working. The OP made no mention of those symptoms though. So he is right - get that code and go from there.

Autozone ..... Code threw!!!! Please write down the code and not the usally incorrect diagnosis the counter dude gives!

Still dont have the code i a hoping to do it tomarow. The ac does work fine and the heat come up just fine. as far as the code for the O2 sen i dont remember the code . I had them wrote down but lost the paper i had them on. And yes it could be the car does just has arthritis LOL .I just thought it was strange that it come and goes with out side temp and other then that runs fine. I have not seen a drop in miles per gal. will get codes and post

ok got the code still saying bad O2 sen p0053,p0102, p0043 I am going to clean out the back and pull the battry cable one more time and go from there ?
