2000 MAP pin to ECU
Hey Everyone,
Looking for someone to double check my work before actually going to do the work.
I am having some issues that we traced to the MAP sensor being all over the place. I am wanting to cut the wires from the connector of the sensor and run new wires to the connector to the ECU.
From what I found, I have them as:
1) Sensor - lt Grn wire - pin 32
2) 5V Ref - Gray wire - pin 48
3) Low Ref - Blk wire - pin 54

I believe #3 is the sensor ground... the pin locations look right though, #1 is in connector C2 and # 2 and 3 are in connector C1... my 02 has the sensor ground wire being orange and black in connector C2 pin 54 so it's different than the wire color you listed but the pin locations are the same according to the 02 wiring, I'm not sure if your year differs

Why do you find it necessary to cut the MAP sensor wiring ??...what do you mean by “it’s all over the place” ???...do you have a particular DTC ???

I have a few DTC codes that i can't remember off the top of my head right now, but was wanting to get this issue sorted first for another problem to have my tuner look at. Never ending

is it an oem sensor?... make sure the contacts in the connector are not spread open and causing a weak connection

also since we don't know anything about the setup, are you using a 1/2/3 bar map and is it possible you switched the stock 1 bar out for a 2/3 bar without calibrating the tables in your tune and/or switching the operating system?
