scangage ll oil pressure


Recommended Posts

I have a scangage II that I use as a monitor and want it to display my oil pressure. Has anybody been able to get it to read the oil pressure from the pcm.

I haven't been able to figure how to get my truck to show at the bottom of my posts so any help would be appreciated so here it is

I cant make any sense of the schematics in my manual but I went to a local shop and they looked it up on ALLDATA and it shows that the oil pressure signal from the sending unit goes to the PCM so I would think that the scangage should be able to see it. Has anybody found a web sit that lists these numbers that I can try.

98-02 use a oil pressure sensor, so the PCM/ECM does see actual pressure. Depending on the year, and/or flash, the gauge on the dash is fake and algorythim driven. The sensor is an actual sensor, but that's about as far as the real reading goes.

 

The Scan Gauge could probably be programmed to read it, but good luck.

 

The 03+ trucks are even more hindered as all they have is a 6 psi switch, not a pressure sensor.

I even called Ultragauge & they are unwilling to delve into our generation of trucks for any more information.

I think I am soon going to drop some major coin on a Drewteck Cardaq to be able to decypher the SCI bus, OBD II signals & the J1939 data port.

It's a lot of money, but inquiring minds want to know.
