Is this juel injector plug?

[rnln]

Hi guys,

smog check due in a week, I rush to do tune up. While replacing spark plugs, I realize that 1 of the 3 plugs is broken. Is it the fuel injector plug? Does anyone know any kind of plug will fit and if I can get it somewhere local instead of waiting to order online? When I get the plug that fit, can I just cut and solder/grime the wire?

Thanks guys.

That looks to be the connector for the Cylinder Head Temp sensor. Very important that it gets repaired or replaced. You can probably get away with taping the two ends together temporarily, but it will need to be replaced. URO sells one that is cheaper than the Porsche branded one, and it works well. I have had the URO version for 5 years now with no problems.

thanks. Do you still have the link?

You can search our host for one that matches your model year. It should be about $124 for one. For my '87, it is URO 930 606 915 00.

If you have one available, check your Porsche Parts Catalogue for the correct part #

A side note on the CHT in your car. It appears to be the older single wire sensor. the newer sensors are 2 wire as they include the sensor ground as well as the sensor signal. the early 1 wire relied on the engine block as the sensor ground. T Fortunately Porsche designed the original wiring harness to incorporate both leads, so the upgrade to the 2 wire sensor is simply plug and play and should add some degree of improved accuracy to the CHT data for the DME.

I think the OP plans to only change the plug and keep the original CHT. Hence the answer from 917 above. Junior (Power) Timer is the name for this type of plug.

Some reading here.

Plug is probably available here.

Don’t you mean jewel injector?

Based on the second picture, the connector to the harness looks fine but the CHT plug end looks like it crumbled from age. The only fix here is to replace it with a new one.

917_Langheck/ wazzz,
I didn't understand what 917_Langheck was saying. Now I do lol. Thanks guys.

I am looking at corsa-technic and can't tell which one would fit. Have you experienced this and know which one?
By just looking, I think the JPT-2P makes more sense than the JPT-3P huh
Thanks again.

76FJ55,
Good to know. Thanks 76FJ55

Thanks "Ok here we go",
I plugged it back and tried to tape it then start the car, it's ran fine. I will try to see if I can find the socket/plug first. If so, then I can just cut the wire and reconnect at the socket. That will be the cheapest/easiest solution. If I can't find the socket, then have to go with the new one. One thing I know is that installing the sensor can be hassle, because it involves with the air gap such and such.

Thanks everyone.

Since it is a 2-pin sensor, I guess the JPT-2P (first on the page) is the one. It is apparently sold with 2 male pins ready to be crimped to the wires.
No air gap for this sensor, but still a PITA to replace, so it may be worth trying this cheap and easy fix first.
FWIW I still have the factory original CHT on my 88. Some day I'll have to change it, but meanwhile, if it ain't broke...

if you ar not hung up on originality .. Two bullet connectors will get the job done

or you can order the connector and replace just the sensor end

Those connectors and pins are the most popular in the 80-90 automotive market. I have those by dozens .. and they are easy to find, to work with, and to repair.

In all likelihood, replacing that head temp sensor from 40 years ago will be a very bad experience. Best to avoid it and just repair the connector.

What I worry is that since it is a sensor wire/plugs, I afraid it might require to be special like the oxygen sensor (air tight and such). If it is just normal wire connector, I'' get that (gorskined's link). Worst case, I replace both side.
Thanks everyone.

[wazzz]

Nothing to worry about air tightness like O2 sensor. This CHT sensor is merely a termistor, i.e. a resistor whose ohm value varies with temperature.

Joule injector. That would be handy.
