Turbo MAP Boost Sensor Replacement Options

[LikeUCare]

Hi, have a 94 SS with a bad MAP, tossing CEL 45 and fuel cutting during acceleration and just going down the road intermittently. Took to the dealer and confirmed what I had researched on here and quoted over 400$ for the OEM Turbo MAP. I told them to go piss off and put an ad in the Parts Shed and been all over the web looking for the stock Denso 22012AA020 3 wire OEM MAP without any luck.

So, my question is, what other options are there? I see tons of 22012AA070 Denso MAP sensors on eBay and the plug looks right and I suspect it MIGHT work but wanted to see what others have done. I have a TD04 with wastegate actuator bypassed and MBC but the car has been running just on wastegate (7psi) pressure since engine rebuild around 30K ago.

I suspect the sensor reading range on the turbo versus the NA MAP is different (read somewhere 2 versus 1.5 bar) but if I am keeping boost low would this matter?

Any other cheap/easy options out there? Thanks in advance for the help.

I may have a used one stored in my parts stash. I won't be home tell late tonight to check, but if your OK with a used one I could probably let it go for $40.

If he doesn't want the used one, I'll take it

Code 45 is for the Pressure sensor and pressure exchange solenoid valve. Your problem is more than likely the pressure exchange solenoid which is a pretty common problem with these cars. New ones can be had for around $100. You can get used ones, but they are likely to fail again in the near future.

He never replied so I guess it's up for grabs. I think I have the whole bracket with pressure exchange, map, and wastegate solenoid.
Did you need just the MAP ?
