Sorry, I didn't mean to confuse.

Volvo calls the part a "pressure sensor" in both the repair and parts manuals and I've always called it a vacuum pressure sensor hence the VPS reference. So just another name for the MPS, manifold pressure sensor.

Volvos built after August are usually called the next years model, so the "015" is probably the original 1 for your car. I hesitate to recommend 1 over the other as your engine doesn't have the stock compression and to complicate things, you can't get the same octane gas as Volvo suggested back then nor was there ethanol added.

Most if not all of the Bosch long part numbers have 10 digits and the part number on the reman sticker is correct if you omit the last 3 digits and I bet you'll find the same 10 digits stamped into the case of the ECU.

I use FIC to rebuld my customers VPS/MPS and in fact I just got an "035" back from them for a customer's 1973 1800ES last week.
