wasted talent Posted December 2, 2017 Report Share Posted December 2, 2017 Hi all, I have a vdo 5 bar fixed ground sensor that i know is accurate pressure/resistance and am trying to wire into g4+ plugin to verify a suspect sensor. what is the best way to wire in and configure a sensor with only the one wire connection?

Adamw Posted December 3, 2017 Report Share Posted December 3, 2017 These are not great sensors for aftermarket ECU's/loggers that have 0-5V inputs. Because of the low resistance you also need a low value pull up resistor to get a reasonable voltage range out of it, but that makes it burn a heap of power so you have to compromise. The ECU only has a limited amount of 5V power to power all attached sensors. I would use a 200ohm pullup resistor which will give you about a 0.4-2.4V signal to the ecu. If you give us a link to the data sheet or calibration data for your sensor I will show you how to do the Cal in the ecu. Quote Link to comment Share on other sites More sharing options...
wasted talent Posted December 5, 2017 Author Report Share Posted December 5, 2017 I'm limited to using my phone for the next couple days so attached is the best i could find. it is VDO part number 360-081-029-041C . all assistance appreciated Quote Link to comment Share on other sites More sharing options...

Woody Posted December 10, 2017 Report Share Posted December 10, 2017 Hi , sorry for crashing the post , would this work with a LS1 oil pressure sensor. Cheers Keith Quote Link to comment Share on other sites More sharing options...

Cheers Keith A quick google suggests the LS1 oil pressure sensor is a 3 wire unit. It will most likely be a linear 0-5V output, you will not need a pull-up or calibration table like the VDO sensor in this thread subject.

Woody Posted December 13, 2017 Report Share Posted December 13, 2017 Thanks Adam , the one one i have in the block is a single wire one , i am going to replace it with a 3 wire type. Cheers Keith Quote Link to comment Share on other sites More sharing options...
