Bench Testing $8D ~ Error code 33 Map Voltage High

[dave w]

I can test $8D on my test bench/harness I built. Never had a light for the map sensor. I have a vac pump hooked up to the map sensor to give it some vaccum when running the system. But even in the few times I ran the dist with a drill and never gave the map sensor any vac, I never got a map sensor error code.

That's what I was wondering. I seem to remember, the other $8D systems I bench tested did not have MAP error codes. Maybe I need to try a different MAP sensor? Thanks for the input JeepsAndGuns.
