High exhaust manifold pressure.

[Luckywon]

Good morning and thanks for the reply. The backside Komatsu monitor (service side) gives a lot of info. In this case I can see supply voltage and the pressure reading. What I can’t see is signal voltage. I agree I think it should be about 14.7 psi with nothing turning. There are many other parameters I can view if you think of any I should take a look at. I’ve also tried watching these parameters and having a helper wiggle the hardness from sensor to ecm and I did not see the values bounce at all on the monitor.

QOTD: what does it mean when a sensor reads high when its reading the atmospheric pressure? Bad sensor?

I tried attaching picture of the Komatsu monitor. In the pic you can see some of the channels that can be monitored.
