I was wondering if you guys could help figure out where/what source of air goes to the lines of the Map/baro solenoid. I also have another solenoid that was running along the Vacuum Gallery that looks exactly like the Map/baro solenoid (not the EVAP solenoid).
Here is the picture...
K5T46581 7924 : Map/baro Solenoid
K5T46583 7923: Another Map/baro Solenoid????I'm not sure?They look the same...
I should also add I did removed the vacuum gallery, to clean up the bay a little (hoses were disconnected/cut a while back). So I want to hook back both solenoids (minus the EVAP solenoid). Something tells me ill be shooting in the dark on this one...
Going by your A,B,C; A is the single metal nipple, B is the middle plastic nipple, C is the last nipple.
Green solenoid controls EGR.
A- Vacuum from intake manifold
B- Back pressure transducer, AKA EGR valve
C- Fresh air source, from intake resonator
Brown solenoid controls Boost/MAP sensor.
B- Boost sensor
C- Fresh air source
Black solenoid control EVAP.
A- Fresh air source
B- Vacuum source with check valve
C- Evap canister purge control valve, AKA little black disc on intake manifold
The vacuum gallery is the most over engineered pile of metal spaghetti in the world. Its way confusing and overly complicated. I removed all of it years ago and mounted all 3 solenoids and boost sensor to a metal bracket near the ABS actuator.
I think I may have a similar issue with my map/baro sensor. I started having a stalling issue only when coming to a stop. Acted like it was starving for fuel. Here's the list of things I replaced: IACV, fuel pump, TPS, Cam PS. Took TB off and thoroughly cleaned it. (Thanks Pohmr for great right up). Can I test map/baro like most sensors? As long as I'm getting X volts then it's good? It's starting to stutter and try and stall even under acceleration. Only happens when engine up to normal temp. Doesn't happen every time it's driven. I'm at the end of my rope. Any ideas?
so when you say vacuum you mean a hose directly off the manifold not the airbox/intake? the reason why i am askin all these questions is because i am currently fixing all vacuum lines and i just want to make sure its right the time. and after a lot of research this is probably the most helpful info i've come by.
