I just replaced my supercharger harness… and now my boost gauge is stuck like this… not sure how I went wrong. The part number of the part replaced is 12580695…. Any

help?

 

I had to Google that as I'd never heard that term before. Looks like its the vacuum hose assy for the FPR/LIM/MAP.

I'd look take a look at it again to make sure everything is plugged in and seated. Perhaps one of the connections popped back off?

 

Thanks man, I wasn’t sure what it was called… guy at Chevy called it 1 thing.. google says another 😠 you know. Thanks for the help.

 

Check this one specifically that goes into the LIM.

Strange this would cause the gauge to stop working. I dont think this goes to the MAP, right? Hard to remember since I re-routed all my lines. Either way, if any part of this assembly is not connected it could cause problems.

 

I think you've got them mixed up a bit. The one at the top should be LIM, top right T should be FPR, right should be BBV solenoid and left is MAP of I remember right.

I am in the same boat as you though, I had to Google some pictures to jog my memory as I also just redid mine with aftermarket.

Harness does seem to be the right word tied to that part number, its just confusing to the average person as harness generally implies electrical. Not sure why they named it that.

The other thing I'll say is most people don't bother getting another stock one when it goes bad. Nothing wrong with doing so, but it just seems like most just cobble together something with some cheap plastic Ts and cheap parts store hosing.

 

I got the problem sorted out, also though is my car running hot when it going past the middle way a little bit ? Or that’s normal

 

Good to hear! Do you mind posting what it was specifically? It could be useful for future members searching this thread later.


Sorry I cant help with the temp question. I don't have a 6th gen, so I don't have a good feel for what's normal on that gauge as theyre not necessarily calibrated to a 1:1 readout. TBH though a scan tool is the best way to see if theres a problem or not. Thatll let you see actual coolant temp to judge if theres an issue.

 

Brooo bless me with this knowledge I've had this issue for a few months and I'm ready to go crazy lol
