2nd map sensor to monitor crankcase pressure.

[242ATL]

I'm looking to monitor crankcase pressure. I am going to use a GM 2 bar sensor using one of the Spare Analog (ADC) inputs.

My question is regarding the 5v signal to the map. Can I take it from the TPSref from the v3 board, and if yes, which port would you run the 5v wire out of the MS case?

Thanks.

you can use the tps vref (5v) out from the ecu to feed both the map and tps sensor pin 26 on the mainboard connector.

Yeah, I was hoping to stay out of there... those wires are so small to begin with. Good to know tho... I didn't know how many things could be put on that.

Use the existing TPS VREF that is in your wiring loom!
