gav1 Posted September 25, 2022 Report Share Posted September 25, 2022 So I have a gearbox oil contamination sensor which outputs 0-4.5v dependent on metal in the oil. the sensor also has a 2 wire pt1000 temp sensor. i wired the two temp sensor wires to an temp 3 and and sensor gnd via the expansion cable.. i then added a calibration table based on resistance vs temperature . 1000ohm = 0c , 1573 = 150c . when i check sensor resistance with my multimeter it is showing 1100c right around 25c which is correct.. the g4x is showing error and reading 5v not sure what i have done wrong. also with the oil contamination sensor reading 0-5v output . where can i wire this into? any help is much appreciated Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 25, 2022 Report Share Posted September 25, 2022 The contamination sensor, red to 5V, black to sensor ground, white to any spare AN Volt. Attach your tune and I will take a look at the temp settigs. Quote Link to comment Share on other sites More sharing options...
gav1 Posted September 26, 2022 Author Report Share Posted September 26, 2022 Hi, here is the file , the contamination sensor has 8-16vdc as the input voltage so i have wired it to the ignition/batt 12v switched. though it does seem to be playing up as its giving out 10v when it states 0-4.5v output on it very odd. paul r33gtr 811map pump fuel gate.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 27, 2022 Report Share Posted September 27, 2022 How sure are you that you have a 12V version? Typically this would be special order only and the 5V one would be the commonly available option. Why do you have it connected to an AN temp input?

gav1 Posted September 27, 2022 Author Report Share Posted September 27, 2022 Hi, yeah the oil contamination signal wasnt wired up yet, shouldnt be on an temp i was just looking at the settings wasnt meant to save it on that one. I now have it on the an volt 4 input via the afm rear signal wire. and have set up a calibration table vs % reading regarding the version - I am going by what is written on the sensor, it came already installed on my ppg sequential. paul r33gtr 811map pump fuel gate.pclx Quote Link to comment Share on other sites More sharing options...
Adamw Posted September 27, 2022 Report Share Posted September 27, 2022 So where did the 10V output come from? where you just measuring with a voltmeter or something? Quote Link to comment Share on other sites More sharing options...
gav1 Posted September 28, 2022 Author Report Share Posted September 28, 2022 Yes , exactly. i need to run the signal wire to the enginebay (to the afm connector) which i hadnt got aound to so was trying to get a reading and that way an idea of my oil condition. was surprised to see 10v . i guess i could see what 5v input voltage does to the signal voltage output , maybe the sensor was labelled wrongly at factory.. does the temp sensor settings look correct on my map, and now the contaminant settings ? also am i correct in using any of the sensor grounds to wire the temp sensor? it doesnt have to be on the same expansion slot? thanks for helping Quote Link to comment Share on other sites More sharing options...

You dont actually have a temp input assigned or set up, but cal table 2 does look ok for the PT1000. And yes the oil contamination setup and cal looks like I would expect it to work.

gav1 Posted September 28, 2022 Author Report Share Posted September 28, 2022 oh , think i put it on wrong i had it on an temp 3 , but now i see that says engine oil temp, i will swap it around and try again. just wired the contamination sensor up to the 5v ecu output instead of 12v and it is reading 0.5v from the signal wire . so i guess the sensor just has the wrong print on the outside very odd.
