Hi, all. It seems like the supercharger in my 2000 SSEI has stopped working. The car starts and runs fine but it doesn't have the power it used to. When I give it full throttle, the boost guage only shows about -1 PSI. It never gets above zero. I've verified the T-connector on the vacuum lines under the snout are connected. I've also checked that the lever on the boost control actuator moves freely with no binding. I moved it by hand and it moves on its own with the engine running as I open the throttle. I haven't had any other noticeable problems and the SES light has not come on. I'm not sure what the problem could be or what to look at next. Any ideas?

Could be a bad gauge.

Just a bad guage when there'* a noticeable lack of power?

Hmm, pull the belt and check for play. Could be a bad coupler. Can you hear the rotors spinning?

i figured their belt snapped or like said play in the snout but you would know if your belt broke

The belt'* not broken. I'll check for play and report back. I bought a new coupler a while back but never put it on because I couldn't get the coupler off while still on the engine. Maybe this'l be my excuse to remove the SC.

Check and make sure the boost controller isn't sticking. There should be a black circular object attached to the SC, if you rev the engine from under the hood do you see the arm coming out the bottom move? Also, with the engine off, does it rest in the fully down position and can you easily move it by hand?

When you start getting to the point you would be creating boost, do you notice and strange noises, chugging, anything else strange?

or unplug the boost control sensor.i was only getting 2 psi until i unplugged the bcs and bam!!!! 7psi.

Where'* the sensor located?

I was busy this evening so I couldn't get any work done. I plan on taking a look tomorrow after work and I'll let you guys know what I find.

Should be right on the front of the supercharger. There will be a vacuum line and a plug.
