How To Change Oil Pressure Sensor On 2009 Cat C13

Helping out an uncle. 2008 Kenworth W900, True cat C15 MXS.
108-iii Barometric Psi Voltage Loftier (26)
Has occured 116 times
In last 194 hours
Summary reads that its reading 15psi diag. and information technology doesn't change. I'm bold it has gone to a default by doing this.
It is derating the engine and causing it to hisitate badly when get-go started until information technology warmed up...then it will come and go.

I checked around the wiring harness looking to encounter if I could discover an issue. Found some carve up wires at the coolant diverter valve..only it is functioning. Will be fixing those.

I do not take a manual on this engine. Is there a Barometric Psi Sensor in the intake...or is it getting this reading from another sensor?

Any help would be peachy appreciated. Cheers alot!

Okay, from what I can gather...the -three will probably be an open up excursion. Found the sensor by doing some earthworks on the web. Looks to be behind the fuel filter on the C15.
Will exist testing the harness and feed voltage. From what I have read looks like it needs 5volts to run correctly. No more than than .five volt difference when wiggling.

Is there a way to examination the sensor without getting a new sensor? What about resistance tin can that tin be checked?? I could not find the ranges. Does anyone know?

From what I can gather seems all others sensors depend on this sensor to get an initial reading....say a standard to start their readings with. Many other sensors employ this sensor. Trying learn what I can virtually it. First fourth dimension I've run into this.
This sensor is located depression on the drivers side of the block. Information technology too has the oil pressure sensor along side information technology. Usually with this fault code you have a broken wire betwixt this sensor and the ECM.
this sensor is what the ECM uses in human relationship to boost to determine how much fuel to inject into the engine.
I was wondering when you lot would popular up. Thanks alot. I found some data on it...simply it was most a D10R dozer. I assumed information technology would exist close to that. I'm getting kind of a crash course with these sensors. Seems like there are WAY more wiring issues than anything else. I did happen to find what pins to use on the harness for testing purposes.
And then just for my knowledge. What exercise various pressures do for fuel management? I empathize what it does to the atmospheric condition and how information technology work...merely want to understand what it does in engine management. I did read where an RV got a barometric pressure fault from having high crankcase pressure which was bravado dip stick out of engine. What are the ranges that the sensor reads fifteen to 30bars or what?? What is the human relationship between the 2? One up one downwards....both up....both downwardly?? Hope I'm non abrasive you...only trying to learn how information technology works, non just how to fix it.
Tested it all out...everything seemed fine. Was about to tell him to go a new sensor...every bit wiring and ECM tested ok. Had a sensor off a known good truck and it worked fine after installing it.
And then merely because I ever do this anyways...I went in and cleaned up the sensor and lubed the gasket and cleaned the connections and viola...it works at present. Must have not been making proper contact before. I had to take the connector off the sensor to get my multimeter prongs into the plug..then put information technology back on. This must be why my connector and wiring test passed.

I ohmed out both sensors on the supply and sensor sides compared to the return line and both sensor ohmed out the aforementioned...then until I cleaned it and reconnected it I really didn't see why the sensor would not work.

Glad he asked me to look at information technology instead of listening to the shop in town...they told him automatically after reading the code to guild a new sensor...

Thank you for explaining the sensor to me.
Would an atmospheric force per unit area sensor on a 6nz exist calibrated different than C-13
