been having issues. Now it seems as if I don’t have 5volt reference on tps,egr . How can I test for that? I ran a volt meter ground then to the white black wire nada. Ive been calling ecu exchange & they aren’t responding to my emails any ideas?
No volt reference?

I believe you need to test between the ground and the 5V reference at the device. Using a chassis ground doesn’t really work.

Sorry meant to erase the post o do have 5 volt reference I keep getting code 29 the vss i have it in another post, there are some weird things/issues that I have happen on cars I’ve seen. So I’ll ask ,anything that could cause me getting a code 29 other than the normal ? In other words can a diffent sensor like a bad maf cause that? Just asking cuz I’ve been thro everything & can’t figure this out . Until I can borrow/swap another ecu I can’t eliminate that from the equation. I can even get ahold of anyone at ecu exchange. Know another ecu place? I am tempted to take it to altex there is a guy that works on circuit boards but don’t think that car ecus are his expertise
I doubt ECU Exchange will answer the phone but I’ve never tried. Did you send it off to them and have questions or just want to ask them questions to see if you can determine if it needs to be gone through? Of it’s the latter I can tell you it won’t hurt to just send it as pretty much everyone that sends their to them get the power supply and other end of life parts replaced as they are noisy or not up to spec.
If it’s your primary mode of transport then I would highly suggest you just buy a spare. I had three at one point but sold one with a harness as it didn’t make any sense to have three.

No I sent it to them and they said it passed. I thought maybe it was something else on the car but I’ve replaced pretty much everything with exception on spark plugs now I have no idea what to do cuz I don’t have a clue what it could be I already went over everything more then once I did have a da1 but I sold it if I remember correctly it did run with it I think I just disconnected the maf and ran a vacc hose to the map to make it a bap
