: Sensor Readouts?? How to get them??

02-07-06, 07:20 AM
I have an 84 Deville w/ HT4100 and I would like to figure out how to get the readouts the various sensors are inputting to PCM (coolant temp, air temp, TPS etc). Can this be done on the ECC or do I need a Tech 1?

I don't know that car well enough to say, but in my 85 Cutlass I used to drive around with 3-4 digital volt meters (DVM's) and a cable running out to all the sensors I wanted to monitor. I prefer to read O2 and TPS inside the car AT the PCM.

I learned a lot that way.
