How much is computerized?
I was wondering just how much of my truck is computerized?<br><br>I heard discussions about TPS (Throttle position sensors) and Crank Case Position sensors.... how much is computerized?<br>The injection pump is mechanical... so why the TPS? <br>Whats the Crankcase position sensor used for?<br><br>I also know that there is electronics dealing with the transmision as well... ???<br><br>Also, I know that the ABS system is tied to computers....<br><br>How much is computerized?<br><br>Would/will these trucks continue to run if any of the electronics fail?<br><br><br>Just curious.<br>Rich.

It might be differant on the Cummins, but on my PSD the CPS is actually a Cam Possition Sensor. It does several things, one of wich is give the signal to the tachometer.

PCM controls intake heater; provides analog signals to drive gauges from inputs like crank position sensor (rpm/tach), water temp, oil pressure, fuel level etc. Auto trans is PCM controlled to some degree AFAIK (TPS governs shift points along w/input from engine speed and driveshaft speed), but I have 5 spd so can't say from "hands on" work on the 47RE or other trannys. The PCM does control charging rate of alternator, based on load/voltage/temp - but does not control the fuel shutoff solenoid, if memory serves...<br>-Scott
