Gti6 Sensors

[24seven 104]

I'd do a search for these questions as they've probably been covered, but search is still disabled.

 

Anyhoo, I've come up against a couple of differences between the GTi6 loom I've got and the sensors on the Phase 2 multiplex setup on the engine that came out of my donor phase 2 VTS;

 

First, how many pins/plugs does the lambda sensor have? I vaguely remember the 306 1.8 16v I had a couple of years ago having a single 3 pin plug for the lambda and the rest of the sensors all matched the '6. I'm pretty sure I can't use the lambda from my 8v motronic which uses a pair of 2 pin plugs anyway, but just wanted to check as there's a couple of plugs on the converted loom I'm not 100% on yet.

 

Can I use the 8 oil pressure sensor in the XU10J4RS engine? I did ask in the GTi6 sensor thread a few days ago but with it being an old topic pinned I guess it isn't read very often. I'd like to keep my pressure gauge working as I've already lost one Mi16 to oil surge so would like to keep an eye on it.

 

How many pins does a GTi6knock sensor have? The one on the VTS block has 3, but on the loom I have there's only a 2 pin plug and I'm wondering if that's it.

 

Thanks in advance.

Lambda is a 4 pin connector on a GTi-6, on a sliding latch-like connector similar to various other late 90's Peugeot/Citroen's.

 

You can use an 8v oil pressure sensor, but you'll need to fit an adapter as it's the wrong thread - 8v sensor is 10x1 and the block is something like M14/M16

 

GTi-6 knock sensor is 3 pin, same as other XU10 engines. The wire on the loom should be shielded from memory which should make it easy to find.

 

Edit - just checked my spare GTi-6 loom - the knock sensor is a shielded wire with a 3 pin green plug, located on the loom not far from the injectors, oil temp and oil pressure wires.

Hmm, ok thanks . The only wire with any sort of shielding on the loom I've got here is the speedo drive which has some wrap around it to protect from the exhaust manifold.

 

I'll get an adaptor sorted for the oil pressure sensor. If I can't find one 'l make one in uni. I mistook that sliding-latch plug for something else while I was looking at the loom in situ earlier. Makes sense actually as it lies near the back of the engine bay.

 

Thanks again mate, very much appreciated.

 

[edit] Just to ad to the confusion, I had it backwards. My knock sensor is a smaller 2 pin plug while the loom has a 3 pin connector. Still, that clears that up, I need a different knock sensor.

When I say "shielded" it's internally shielded, rather than the external heat-resistant covering used on the VSS wire.

 

Basically, the shielded cables (crank sensor, knock sensor) have wires that are noticeably stiffer and harder to bend than the unshielded wire used by most other sensors.
