Hi. I am new to this forum but I am not new to the internet forum arena. I am on many other forums but have never owned a ford.

Welll I just got married and my wife owns a 2001 ford f150 5.4 V8 4x4 (now thats my kind of woman) She refuses to drive cars or minivans ha ha

It was always a great truck while we were dating and we took it everywhere. Now that we have been married a little over a month the truck has been having problems. The check engine light came on, it idled weird when cold, and the gas mileage went in the crapper. I will try to keep this short but detailed

First we got a MAF sensor check engine light so i cleaned it but that did not help... so we replaced it. That was the only check engine light stored in the computer so we deleted it. A couple of hours later the light came on again and I was sure it was going to be that dang MAF sensor but it was a different code and only one code...

The code was for the TPS... I was getting a little frustrated so I quickly changed the sensor in the parking lot of the autozone and then deleted the check engine light. After about 2 days we were pretty excited because the light had not come back on and it was running normal again. It was not idling weird and the gas mileage seemed a lot better.

Although on the third day the light rose again GRRR!!!! This time it was P0107 MAP sensor... I was a weary about a completly different light coming on so i just deleted it in hopes that it would go away. When the check engine light is off the truck runs great... but after a couple of days the light always turns back on!!!

I have searched the internet long and hard and it seems that the P0107 is not a very common CEL for my truck...




Please if anyone could help or give me any advice that would be great!!!!

Thanks

 

What did you use for a replacement MAF sensor?

What did you use to read the codes?

Since your truck has neither a MAP or a BARO sensor, I'm trying to figure out how you happen to have a fault code for MAP/BARO sensor.

 

The MAF uses an algorithm to figure out the BARO and MAP based on intake air temp and measured voltages from the MAF.

 

well i just went and bought one from autozone. It was 150 with a 50 core charge.

That is weird... I did not know the truck does to have a map sensor... why would I be getting a map sensor code?

My code reader is broken so i just went down to autozone to have it scanned.

 

Starting to sound like a replacement MAF whose calibration doesn't match what the PCM wants to see.
