Default Inaccurate Boost Gauge on 93 SSEi

I have another irritating little problem: My boost gauge is very erratic in operation. Just started doing this. The "trend" information appears good, but the actual reading is obviously inaccurate. Is this a dash cluster connection issue? Or what else could it be? thanks again in advance for your insights!

Sometimes the sensor can go bad, sometimes the gauges cluster begins having issues.

Where is the sensor? Can one test it to determine if it is bad? Easily replaceable? Thanks, STEver

Hello, Fuddy,
I looked at your earlier post as provided, however the photo you were referencing did not show (Got the little red X). Anyway, hate to bother you but would you consider sending me the pic via e-mail? Would appreciate it. This is the pic of the SC with the sensor (the black horizontal triangle thing......). I don't see a horizontal triangle thing on my car. Anyway, the e-mail addy is "[email protected]" if you send it. Thanks for the help!

My 93SSEI boost gauge started jumping around eraticly, took it in and had gatorbacks installed, thought the belt was slipping. During install of belts tech told me my upper tensioner was poor.
Having new tensioner installed later today. Will see if that corrects problem.

My boost gauge fluctuations were resolved by replacing upper tensioner. Part #24501383 tensioner (dealer item) list 75.72 wholesale 56.79.
1 bolt 10 min.

Well, the new gatorbacks I had put on yesterday seem to have fixed the erratic gauge operation problem!! It is now operating in a smooth, stable fashion. Turns out the tensioner was OK, but the belt must have been slipping. Upon inspection the belt was pretty old and cracked. I had thought the belt was replaced when I had the supercharger replaced a couple of years ago, but the receipt showed that they weren't so the belts were older than I thought. Bottom line: slipping belts. New gatorbacks fixed the problem!

Few questions then.. to determine how they figure out its the belt?

Did your car

a.) Hit boost.. then dump it??
b.) If not.. did it always just go all over the place without some sort of a pattern??
c.) how they come to the conclusion that it was the tensioner or the belt ?? (troubleshooting)
