2001 sierra map sensor

[jaybird*oh]

 Need a map sensor for my 2001 sierra 5.3 and find there are an array of part numbers that apply and prices from 8.-$  to 85.-$ .  Some GM brand are made in Mexico and some no name made in US. Any suggestions welcome.

I usually just take the OEM sensor and find it on ebay or where ever to get a matching sensor.

 

Some parts stores will carry AC Delco/Denso parts, otherwise I go right to the dealership.

 

Here is the part number I found for that vehicle, it's a new AC Delco part.

Why do you think you need a map sensor?

 

If I were going to get one I would get https://amzn.to/2V4crjF. All a map sensor has to do is read pressure.

I'm getting a p0107 code so I checked map sensor and the (orange) ground wire is good, and the (grey) wire receiving 5 volts to the sensor. The (green) center wire.(out) registers 0.02 v at 5" to 18 " vacuum . I understand that this voltage should vary with vacuum as in idle or under load. I'm 82 and not real familiar with pcm's and sensors but I'm trying to learn.  This truck started to run erratically last week so I'm attempting to pinpoint the problem. Any help appreciated.
