Default Error codes, P0108, P0171,P0174

2000 MPV
The P0108 says "Map/Bar0 circuit high input", the others I found on this site indicate bank1 & 2 are too lean. I was thinking the intake manifold gasket is leaking? My VIN isin this range. I would like to check the torque on the manifold. Can someone please provide the torque spec for the intake manifold?

I dont know if this is it or not but its free to check. I also put some cleaner/fixer stuff in the gas tank incase the gas is bad or water in tank.

Not sure about sensors? if someone knows what P0108 means in laymens terms? Is this the map sensor dirty/bad? If so where do I find it...
Many thanks

Follow up...the P0171 and P0174 codes are gone..P0108 wont go away. I would still like to know the torque for the intake manafold screws. The detail report on the diag tool says Fuel Sys 1 OL Fault. Which seems to make sense since Map/bar0 Circuit High Input is the text for this error. Any ideas?

My 2001 mpv has a P0108 and my mechanic tells me it is a faulty MAP sensor. Was that what yours turned out to be? I am curious.

Well I havent fixed mine yet. I think it may be the hose? The sensor was $225. Not going to shot gun it at that price. I was out of town. It runs fine just has the light on. I have cleared it but it comes back on. I had some fluid on the connector, not sure why so I may just clean it all up, reset the light and see what happens. This sensor doesnt typically go bad according to the parts ppl.
