986 Interior Monitoring Sensor

[1schoir]

Looking for a photo of the interior monitoring sensor on an early Boxster ('97).

I have a long standing fault code from this source and would like to know what the unit looks like.

Maurice, I do not have any photographs, but I do have an "exploded view" of what Porsche calls "the front roof lining", which is basically everything at the top of the windshield if that would be of anyhelp. It includes the sensor housing, but does not give any great degree of detail.

What exactly are you looking for?

There was a service notice for the 97 cars on the motion senor,

"Boxster Interior Monitor Sensor Mounting [grp9 6/97 9685 9/25/97] 1pg

False alarm activation from the Passenger Compartment Monitor Sensor may be caused by the bottom plate of the sensor touching 2 locating pins in the front frame. The 2 locating pins have been shortened as of April 18, 1997 production from VIN 986 VS 623312."

That exploded view might be helpful. I wanted to see what it looks like before I go out to the Boxster (it's still cold out here on Long Island) to try to locate and rectify this long standing fault code. I will pull the code and post it when it gets a little warmer here and I'll check my VIN to see if my car is one of the affected ones.

The TSB was helpful also. Thanks for posting that.

It says that the sensor must be replaced, but it doesn't explain why you must replace the sensor if the locating pins are causing the problem.

From the sounds of it, I would bet that the sensor circuit is grounding itself on the pins, perhaps they have modified it to stop the problem. As I have never seen an affected vehicle, I can only speculate.

If you have a fax number, shoot me a PM and I will fax the diagrams over to you.

You are probably correct (as usual) :cheers: .

PM Sent.
