code 81

[greg geraci]

I recently ran a diagnostic and came up with a code 81 Boost Control Solenoid
AIRD soleoid 3.0 sho Inlet air solenoid
where would I find that ?

thanks,

Isn't that the code for the secondaries control valve circuit?

Probably a continuous code with means a MAP/BARO problem.

There is no secondary air injection solenoid on a SHO, it's called something else, specifically the inlet air control or IMRC, depending on the year.

there is a solenoid on the secondary air injection system and it controls the air diverter valve to the manifolds. when it malfuntions it will either be stuck open or shut, if it is stuck open you will feel and hear exhaust coming from the suction side of the air pump and if it is stuck shut it may get the p0411 code like the one on my 97 v8. it is located behind the resevoir on the upper bracket where you find the egr control solenoid as well.i removed the vent screen below the windshield on the right side and you have no problem getting to it then
