Multi-Purpose Pressure Sensor part 55573248

[InfoUpdate]

Not to be confused with the MAP (manifold absolute pressure) sensor....

Anyone know where the Multi-Purpose Pressure Sensor is located?

GM lists that part # as Multi Purpose pressure switch. Everyone else including AC-Delco lists the same part# as a MAP sensor. It should be the same thing like a hood in the USA and a Bonnet in England.

Thanks for the feedback!

Looking at my old MAP sensor it is the same part number after all. I already replaced it a couple of months ago. Made a big difference in performance for sure. I was surprised given that it wasn't throwing a code or anything.

I'm super tuned in to my car and notice every little thing when it comes to performance.

Before replacing the MAP sensor I noticed the engine seemed to want more air when driving. MAF sensor had been replaced 15,000 miles ago so it wasn't that. Who knew we needed a new MAP sensor?

Funny thing is I had that MAP sensor in my console for a year or two before popping it on. lol

I'm convinced when you creep over 100,000 miles, just replace all the sensors you can reach. It will save you from breaking down and keep the expensive stuff happy.

What brand was in there and what brand did you replace it with?

AC Delco was in there and I think I replaced it with Bosch.
