Losh's VR Ute build thread

[vc commodore]

Damn, bitch won't start, it's a flatbed and I only need to get 1km up the road. Lol

Maybe this will help...

Sorry had to have a quick joke about it, so please don't get offended

They call me "Passion Fingers"..... I can explain if needed. I'm starting to wonder if it's me??

The later model L36 or 3800 V6 series 2 (ecotec to us) engines use a reverse rotation TPS, looks the same, same plug etc but opposite orientation. The earlier 3800 V6 uses a different TB to us so I'm not 100% sure if they are compatible but they are a GM sensor so no doubt there would be an equivalent unit on GM engines.

Our V6 motors use ALDL but use the OBD2 plug from VR onward.

Thanks for the info

I have to say that is funny. Not mean disrespect buy I do love dark and sarcastic humour.

Interesting in that the wiring diagram that @wildfiremaint posted shows the earth shared bewteen TPS and coolant temp sensor. It shows the earth as a dot in the diagram but it could be implemented in a number of ways, earth bolt, internal loom crimp, etc... If this earth joint is dodgie, then the TPS reference signal can swing wildly (since the earth can fluctuate between 0 and 5V dependant on maybe vibration or engine bay temps). This is especially frustrating to fault find if it is indeed an intermitant vibration/heat induced issue....

So again it could be some wiring issue is at play as multiple TPS's can't be all be inaccurate/poor quality/faulty... Coolant earth is common to the circuit...

Old school works best when backprobing the TPS sensor wire as using an analogue meter it becomes easier to detect voltage sweep issues as compared to using a digital meter.

You could also try and unplug the water temp sensor and see how that goes

Yes, funny.

Is that the reason LS swaps are popular?

Is ok, I admire your enthusiasm. I can say I am that way too. Hey, I say all have a fix, at this point is a Gremlin that need to be squashed.

I'd have to see if I can find one that fits Fu but that one certainly doesn't.
