OK, thanks!

That's just what the Service Bulletin called for ---

Yup - probably better to NOT use lock washers - more contact area for corrosion to develop...

Only the INFL REST light came on and it was throwing a code 26 which is the passenger side sensor.

Im going to bet the seat belt light for the driver comes on when its the driver side sensor since the driver side bag would be going off on a Left side collision?



I have the GM 88-92 Body Systems # TK03040 ... but the Service Bulletin says to use 91 Body Systems # TK04040 ... will my cartridge still work since it has the 91 in it? It just says don't use a 90 only cartridge?

Thanks guys! ---

I would guess that cartridge has info for all years. it will ask you the year and VIN to lock in the specific addressing and features for your particular year. (if it works). I have one cartridge that is fubar and won't boot, for instance.

OK , thanks Mike ... now to get all the cords I need to get this damn thing to work.

I am getting really frustrated and ready to just sell it and have the dealer start doing the work on my car ---

hang in there. I am in the same boat as you being a new owner. I am learning the acronyms as you are. confusing. I have been lucky so far I have had no codes. I just learned about the tech 1a scanner. I will be looking to get one later. seems that the obd1 on these cars are a pain in the butt. the c5 is much easier and forgiving. easy to pull and clear codes.. I am currently trying to piece together my cars history. apparently it was unregistered for over 12 years?? news to me. Good luck on your z. edramos.

[alwayscode390]

Thanks Edramos!

I think I have the hook up on a cord , BUT I need someone to verify for SURE that I am looking at the right number cord.

I don't want to buy the wrong one AGAIN , and have all this crap I don't need sitting around that's hard to re-sell ---

[alwayscode390]

I have found two replacement sensors while searching.

Both are part number 10177901 .

One is yellow and one is black ... the black one has a longer cord , and says FORWARD with an arrow away from the cord, the yellow says FORWARD with an arrow towards the cord.

Is one for the passenger and one for the driver side?

Also, they all say years different than 1990 with the same part number ... is 90 different than the 91-95's?

Thanks! ---

the MY 90 is a one year only in so many ways. Yes I beleive the sensors are different. I know for certian the DERM and the Airbag are a one year only

I guess I have some corrosion on one of the body sensors or a bad sensor. People were talking code 16 ... how do you find out what code number you are throwing?

Well I went to look for the INFL REST fix that I came up with about a decade ago on the Club "Technet" page and its all gone along with about a dozen other fixes and what use to be called "How To" projects I did. This has happened in this last week. You can still see the entries for them (in the link below) but the content no longer comes up. This may be a systematic purge or something ??????

As for lock washers? YES absolutely use them.
They have not only better holding characteristics BUT
also improve conduction and lower the effects of corrosion
on resistance. Combined with using dielectric grease you can say
goodbye to having SIR (INFL REST) problems.

It is a well known and understood issue. (well use to be) The contact area under the sensors corrode as do the threads on the mounting hardware. The missing article covered all that along with how to sand down the contact area on the frame.
NO NEED TO BUY NEW SENSORS
