Speedometer Sensor

Posted by mister_al (My Page) on

I have a 1992 Pontiac Grand Am (SE) with a V6 engine and Auto transmission. A couple of days ago the speedometer sensor started going out on me--speedometer doesn't work at times; Check Engine light comes on; car runs rough, and sometimes at high idle; stalls out; and the air conditioner doesn't cool. All this happens at about the same time, then suddenly everything starts working (for a while), and then it starts acting up again just as suddenly.

I don't mind replacing the sensor myself, but I can't find out where it's located. I can find all sorts of information on 'speedometer sensors' on the internet except where it is located on this particular make and model car. If anybody can help me out I'd be gratefull.

Phone your dealer and ask him.

I've called 3 different dealers this morning and was told by one that the sensors were located at each wheel, another place told me that the sensor was located on the transmission but he wasn't sure where, and the third place told me pretty much the same thing as the second place did.

I'm going to call them back after lunch and see if I have any better luck.

The sensor is located on the right side axil on the transmission. the wheel sensors are for the a.b.s. That
car is famous for broken wires in that area. you might want to check that first before spending money on a sensor
you might not need.

Thanks for the tip kalining. I hadn't even considered the wiring as being the culprit. I will check it out first thing in the morning.

I just wanted to let everyone know that the problems I was having with my Grand Am turned out to be the Engine Control Computer. I replaced it and everything has gone back to working like it should.

Thanks for the help,
