A "General" test can be performed with a VACUUM PUMP and a DIGITAL VOLTMETER.
A vacuum pump is about $55 unless you have one, and a digital voltmeter is $15+
The Map sensor is $37.99 with my Zip Code Installed
I will run thru the procedure with you, if you still want to pursue this.....My reference is a Hayne's Computer Codes Repair Manual
Another very inexpensive place to use as a resource is a small "U Pull It" type auto salvage yard
The ones I go to, I can get a Grocery Store plastic sackful of any and all sensors, off of any vehicle, for $10 or less.
If you'll take a cooler of soft drinks, and strategically offer a round,
Before your venture, and when you return, from the yard with your booty,
prior to the "Settling Up Proceedings"....Generally, "Price Specials" Occur in your favor!
This is a trip for my neighbor, 8 coil packs, an over-sized rear view mirror, fuses, relays, a scissor jack, etc.....$15
He now knows the Technique!
Let me know what you plan/ want to do
