Boost Pressure High

Recommended Posts

I am on the road today haven’t had a chance to stop and check but my quad is showing 48psi at idle and the quad stays in power level 0

 

Beside a wire could my MAP sensor be dead?

 

When I get home I will look under the hood.

No CEL

 

Stopped to to get fuel and it’s fine now. 

 

Leads me to believe a loose connection.

Usually if the Boost Fooler circuit fails it fails low, to 0. Double check all the wiring, make sure you don't have a short between the power line and the sensor line, that would make it read 48psi constantly on some of the trucks. If you get a hold of a scanner you should be able to read the MAP sensor reading, then subtract off 11 and that should be what we report for boost pressure. If the MAP reads good, but the Quad reads high, then it might be in the Adrenaline. You can double check with the MAP adapter removed and the factory harness plugged in for good measure.

Did see that my wiretap wire had come out and was laying against the injection pump. Reconnected that and everything else looked good.

Well, I hope that fixes it for you. I've never heard of a loose wiretap causing the boost to read high, but I guess it could be possible.
