I do not think that is true.Birdshake said:That broken vacuum line you have is the red line in the diagram in this thread. Its easiest to get to with the doghouse removed.
The line plugs in at the bottom of the intake plenum throat, right ?

I checked mine today, and in-gear at idle I measured 5.67 g/s but I can't say if this is normal or not.pmou said:that would be great! the reason i thought this was low was because in the factory manual under P0101 it states that the MAF should read " 7-12g/s at ide to 150g/s or more at the time of the 1-2 shift"tonydobbs said:If my memory serves the last time I measured my MAF it was 4.6 at idle, so that doesn't seem too unusual. It's going to measure higher when it's cold and the RPM is higher. If I take a drive today I will check the MAF data and post it here.pmou said:It then read what seemed quite low (4.5g/s). Before this, it was reading between 8.5 - 11.5 at low/high (cold) idle.
lol and now that i'm reading this closer it also states that
I'm assuming the ignition 1 circuit is the red lead? i verified resistance from that pin to + terminal. So perhaps this could be the problem? I will double check that resistance (this was KOEO) edit -- err, key on engine off.. i realized i have no idea how to differentiate the O's for off/on in those abbreviations.a high resistance of 15 ohms or more on the ignition 1 voltage circuit may cause this DTC to set. A high resistance may cause a drivability concern before this DTC sets
Definitely replace the crumbling line, but it sounds like your issue is fixed. I wouldn't stress to much about the MAF reading.pmou said:Anyway, following up on the P0101 -- took a longer drive and still no code (not pending either) so that seems promising. None of the MAF numbers appear to have changed though. My manual says 7-12.5 g/s is a normal reading for MAF at idle, however when searching for P0101 and looking at what other people have copy/pasted as the trouble code description, some site 3-10 g/s as the proper range. Perhaps this is a different model year? I have no idea. I'm going to plan to replace that crumbling PCV line with something and then see what I see as far as the PCV system soon when I have the doghouse off. For now, calling the P0101 "Fixed"
I'm not sure I'm totally following.. you are saying there is another vaccum check valve I need to look at? I have a 2003 w/ rear AC, no rear heat.sixsix said:One member is using an aquarium piece - 2-3 bucks if that.
Years later he says it still works.
The CPI motor has 2 check valves in the vacuum circuits.
Ok that's what i thought. we'll see if an actual working check valve solves the issue i guess and then go from there.Leeann_93 said:No. Your '03 only has one.
