[rich a]

The problem im having is this wire with the square plug it doesn't match the sensor on the in let which is ovel can anyone help is the sensor the wrong type or is it the wrong plug on the loom ? can I chop the plug off and solder an ovel one on and does this sensor do anything ?

square plug ovel socket on left the wires are brown/blue brown/red that go to the plug the solid blue wire goes to the knock sensor on the block

[mowgli]

if you can get a correct size plug, just solder it on.
or as I already told you, buy the correct, square CTS.

that way, you don't have to mess with the wiring

[rich a]

Hi mowgli its not a cts if it was id have got one off the bay if u look at the last picture its nothing like a cts. I have an ovel plug that matches but do the wires have a positive an negative so how do I know which way to solder the new plug on ?

[mowgli]

that part no. (650635) claims to be an oil temp sender.

[dgbnova#1]

It is a temp sender I thought it was when rich sent it today but not got chance to look it's got nothing to do with the engine the plugs had me thinking all day FFS lol

[dgbnova#1]

Rich what is plugged onto the knock sensor from you photo I'm sure it will reach as mine looks the same lent has that and correct wires are the same

[ste scott]

It's a air temp sensor the Multi plug has snapped off my wiring loom the number on my sensor is 267063
i need that 2 way vacuum piece if anybody has a spare?

[craig green]

That aint a CTS, the CTS is under the dizzy in the side of the head.

Before you chopping of any plugs, be sure the loom is correct at every other sensor. Does the wire & pug in question not go to the hall sensor on the distributor?

[mowgli]

dr, there are some that have the cts in the water box under the manifold.

[rich a]

Craig its not the plug for the hall sensor just checked that. My cts is on the side of the head under the dizzy an that's plugged in. Just looked at the Haynes manual and it says air intake temp sensor up to year 1990 not sure what happened after that as mines a 91 h plate. Dave had a look at the knock sensor an its plugged in with a round type plug.The only other thing to say is the blue wire that carry's on from the spare plug goes to a temp sensor under the inlet in the water box. One other question how many separate looms r under the bonnet 1 or more ?

[craig green]

It'll be the same until the C16 engine was used, there were one or 2 differences between E16SE setups, not sure if its age related or where you see a difference in distributor types (Red cap or Black)Lucas/Bosch types.

Is the engine running with the sensor unplugged?
By the way I've dug out that 2 port vac part for you.

[mowgli]

just had chance to look in Haynes. brown/blue & brown/red is oil temp sensor wire.

[rich a]

That's interesting mogli Dave reckons i could b the the knock sensor cable is that the same thing as the oil pressure sensor? Would it have any effect on the car if it is the oil pressure sensor lead and isn't plugged in? Craig the car runs ok as this is my first nova im no expert but all seems well although in it is a little thirsty but it could just need setting up properly cheers

[craig green]

If its thirsty be sure the CTS is a good one & check the belt timing is correct (all marks line up exactly).
Otherwise getting the C0 set is a good plan, but only if the garage know what they are doing.

There is no knock sensor on an E16SE

as the good dr said, there is no knock sensor on an e16se.

there is an oil temp sender in the block. there is no mention of this air temp sensor on the e16se wiring pics, which is what I think was confusing me. I'm wondering if you have a mixture of some e16se & c16se (or even c14se) bits. does your engine have a lambda sensor on the exhaust pipe?

[rich a]

First off cheers for the help guys + reps on the way. Mowgli it has no lambda sensor on it or at least no spare wires for it underneath and it has a scorpion ss exhaust from the manifold back. Im now beginning to wander for its redundant an not needed maybe a bit of time spent checking everything like timeing and as craig says the co checking. I might see if Courtney still have guys that used to work on these engines and see if they can set it up properly.
