Problem Fixed (So I Thought)

My check engine light was on so I had Advanced Auto Parts read the codes and these 3 came up P0070, P111F, P0071.

I was told that it was the Ambient Air Temperature because it was reading -40..... so I ordered and installed a new one and that fixed that problem. So thinking that was the only problem, I disconnected my battery for the night, reconnected it in the morning, drove it around for the next couple of weeks and the check engine light was still on....mind you that I'm 2 months past the due date for an inspection so to save myself the trouble, I went and got it inspected and of course I knew it failed because of the check engine light being on. I explained that I fixed the problem (so i thought) but the guy said to get it checked out anyway. WHAT DO I DO NOW.... I thought the Ambient Air Temperature was the only problem?

All feedback is appreciated, thanks

Did you clear the codes after you fixed the problem? Disconnecting the battery for the night is not going to clear the codes.

I hate clearing the codes because it takes about a week for the monitors to set ready.
After you clear the codes the engine light should stay off. If its on, then you have a problem.
Where did you buy the sensor? autozone?
Also check the fuses.

After installing, it read the correct temperature

Thats great. P0070 and P0071 should be gone now.
What i don't understand is the P111f code. I believe that all codes should be four numbers. I dont get the letter F.
Maby he read it wrong. Maby the code is "P1111" which is the 'intake air temperature' sensor.

I think the "ambient temp sensor" you are thinking is not the sensor the code is actually describing. I think its the intake temp sensor which depending on the year will be either on the MAF or on the intake manifold.
