2 things holding it up ....either

1. The sensor is bent at the tip.......

2. Or just a little stuck.... add some WD40 or anything else to lubricate it....and it should slide out.

Could be bent. It's got lithium greese all around it....it's like I'm hitting a "stop" while pulling it out. And it's even all around. I can turn the sensor around while trying to pull it out, and it doesn't change. Almost like it's mushroomed at the end........Say it isn't so!!! :)

Uhmmmm I think we went down this path 2 months ago with this possibility......

Yeah, but the sensor reads ok. I'm trying to split my time between the two 944's. I've got the black one jacked trying to replace the struts. I'm trying to keep the strut spindal from spinning while removing the nut. ...what fun. I'm going to test the pinouts on the harness tonight though, and finish up the suspension tomorrow.

Use an impact and that strut will come out nice and easy. :)

The sensors can have good readings (ohms).... but if you are getting no signal through them the readings mean nothing....

You need to verify the signal... oscilloscope or digital meter capable of this.....

You are correct on both counts. An impact wrench would work the best (going to Harb Freight in about 30 minutes) and the sensor can give the correct resistance, but not the correct signal. The dig meter says I'm getting the correct signal though. Also, the speed sensor in the black porsche does the same thing...ie, won't come out. It's nice to have another 944 to use as a benchmark.

OK, got to test and knock out one strut last night. Would have finished the other, but with two kids and a pregnant wife, my garage time is limited.

Checked pin 13 - I have voltage with key on and w/ clip plugged to the DME. I do not have any pwr when the clip is not connected to the DME.

Pins 8 to 27 and 25 to 26. I have voltage, but am not sure how much I'm looking for.....battery, or less?

Shouldn't be any voltage coming off of the harness side of the DME connector. The 8 to 27 and 25 to 26 are the speed and reference sensors. 1k to 2k ohms.

Socal is right.... if you have voltage you have a short in the harness....

At least to those pins. There is voltage that comes from the DME relay for the ECU and the injectors. I have a picture of the pin outs for the harness/DME some where...

Maybe Wilks has one on his web site.

I'm getting 2.5 ohms between those pins. With the harness plugged into the dme I'm getting voltage. About 2.9 to 3.4 to be exact.

Don't know about the voltage with the DME connected. The factory DME testing plan just checks with the plug disconnected. This is to check the device and the wiring.

Weird. I just got an email that there were new posts in this thread. I wish Hugh was still around, posting for us...

Thanks...
