I just picked up an 88 Seville in MINT condition. I keep getting the code for the vehicle speed sensor and the spedometer doesn't work along with some other electronic stuff that is thrown off by not having a VSS signal.
The digital dash seems to be OK and everything works on it along with the DIC and Climate controls.
I took a look at the sensor and someone had the wires unplugged so I plugged them back in and took her for a ride. The spedometer started jumping around and then went to 85 and started flashing and then THE CAR SHUT OFF. I didn't even get a block from my garage. I restarted it and got it back to the house and proceeded to remove the sensor. When I got the thing off, all it appears to be is a gear driven shaft, nylon on bottom and metal on top that passes in front of some sort of magnetic pickup. Everything seems to LOOK OK so I put it back together and plugged it back in and took it for a ride... same thing happened. So, I just unplugged the wires again so that I can drive the car. It runs OK but doesn't shift quite right and obviously no speed reading on the dash... stays at 0. But at least I can drive it.
I can't think of anything else that could be wrong so I ordered the part (VSS)from cadillac parts dealer.com at a hefty cost of one hunderd and thirty something, normal price being $167. The local dealer told me $167 also.
I was wondering if anyone else ever replaced one of these and what the cost was and if the problem was sloved by replacing the sensor. Like I said, there doesn't seem to be too much to it to go bad. Comments appreciated.
Thanks.
