EGR Temp Sensor Test Plug (2 Viewers)

Does this disable to the entire EGR system? I just want something simple to stop (1) HG issues (2) Protect the wire loom. Is this the solution for me?

Should help protect the wire loom. Stop HG issues? I don't think so.

It's still debated, but there seems to be some correlation with the HG failing at Cyl 6 right near the EGR hole

agreed

HG issues too complex to pin on one thing, overheating for example would be the thing I would ensure never happened to my rig.

Passes Cali smog2 requirements, as of today.

Ordered a kit last week. Looking forward to it.

Figured I would post up a couple photos of how mine looks after it running flawlessly for about a month now. Loosened the bolt for the plug and swung it down out of the way for a cleaner look, you can also see the plug David now provides for the intake. No codes and I can reach my hand underneath the EGR valve after spending a couple bucks on ball bearings to block/plug the vacuum lines. Thanks @LC4LIFE!

Did you leave the egr in place after installing the kit?

Funny story, P401 popped up for the first time in a long time . I was amused since I have the kit AND a brand new ECU harness.

Not many people have the code come up with that scenario. The few I have helped over time have all boiled down to the harness, if not by the EGR pipe, then it was under the dash with some chafing rubbing through the harness. Throw on ohm meter on the test plug to test it. That should answer where your problem is too.

great idea, will do. Hang on, did I forget to transfer the resistor from the old ECU harness to the new one? CRAPPPOLA...I can't remember.

Yep, that was it. I forgot to transfer the resistor over from the old harness to the new harness. Problem solved. It was interesting to me that it took several drive cycles before it came on, then kept returning consistently.

Thank you for the memory job!

Where does this plug go?

Probably the temp sensor hole.

Hi Everyone, I figured I would post up a small project I have been pulling together mainly to satisfy my curiosity about EGR bypass, testing, and making it look good. Many of us have experienced the P0401 code and normally it is an EGR related issue. As you will come to find out, especially...

Not needed on 93-94?

Are you using the temp sensor plug kit that this thread is about? If so then of course you have a temp sensor. It would need to be removed from the intake manifold to use the screw you showed.

there are also pictures in the instructions and back a couple of pages -

That's on the list. Just picked it up for 3100. Needs a little work but its getting there.

It is needed for these years if you want to remove the temp sensor.

Ordered a kit just now, and looking forward to it arriving.
