bsh Posted August 26, 2018 Report Share Posted August 26, 2018 Hi, I just wired a Storm to a LS3, but cam signal is dead, about 1,8V all the time. Crank is fine. We suspected the cam sensor was dead, and tried another one they had and still the same... I just wired in a GT101 and all ok. Engine started right up. I suspect that the sensor pinout I found is wrong, or both sensors are dead, which is unlikely...? Anyone have a 100% correct LS3 cam sensor pinout they want to share with me, as I would prefer to use the oem sensor? Thanks Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted August 26, 2018 Report Share Posted August 26, 2018 It's only 3 wires, should take barely 5 mins to swap them about and test and then you know for sure. Quote Link to comment Share on other sites More sharing options...
Adamw Posted August 27, 2018 Report Share Posted August 27, 2018 The pinout in our help file for the 58X sensor below is opposite to what Stevieturbo's diagram shows. I think his might be for the <2006 black 24X sensor, the 58X sensor should be grey. After testing, can you confirm which is right so I can correct our notes if they are wrong.

bsh Posted August 27, 2018 Author Report Share Posted August 27, 2018 I have them wired as per Stevieturbo`s diagram as it was the on I found on the web. I will try your pinout Adam, but the LS3 isnt listed in the text. Your wiring recommends +5V, Stevies +12V. Why are you using +5V? GM says 12V for their sensors. Btw I have the Grey sensor.

Simon Posted August 27, 2018 Report Share Posted August 27, 2018 I suspect that is a typo in the manual I would also expect them to be a 12V power supply as per factory. Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted August 28, 2018 Report Share Posted August 28, 2018 In most cases I dont think the power supply is critical I know when I tested my LS2/3 sensor on the bench I was using either a 5v supply or 9v battery...cant recall which as it was a few years ago but I know it worked fine. On the car I did use a 12v feed though. Output is still a 5v switch though. But test, it's easy and only takes a few mins swapping wires.

bsh Posted August 28, 2018 Author Report Share Posted August 28, 2018 Thanks Yes will try swapping wires:) Quote Link to comment Share on other sites More sharing options...
gotasuby Posted August 28, 2018 Report Share Posted August 28, 2018 Last ls3 I did had the cam wires round other way. Genuine sensors have icons inside plug of the sensor for terminal function. I ran mine on 12v ok. Quote Link to comment Share on other sites More sharing options...
