When I try to look it up it shows 3 different sensors. How would I know which one to replace?You need a new Vehicle Speed Sensor... do some searching
He's got quite a bit going on with his DTS.... he has a thread going on in the Deville section addressing his other issues..................and jeffrsmith is correct: you have some other serious problems. Serious.
Actually my GM Protection Plan (Major Guard) just expired, so everything has been WELL maintained. I used the warranty with its measly $50 deductible every time something didn't feel/sound right, haha! I really miss it...... That and the basics like oil (synthetic), filters, ect. have all been changed on or before there scheduled date. And did I mention the body/interior is in MINT condition.... with only 65K miles???Yeah that!:highfive:
Do I remove the wheel? I can't seem to find it laying under the car.... or from the top? I purchased the new one just need to locate and swap em! PLEASE..... can anyone guide me....VSS is on top of the right (passenger) axle output casting.
Well I ended up jacking up the passenger side front. I then slid in behind the wheel and when I reach up to locate the VSS there was a metal plate blocking the top of the axle case, so I removed the 3 bolts holding the plate and bam.... there it was held in with a single bolt! I replaced the sensor, vleaned the wiring with electrical cleaner, and put it all back together. Took it for a test drive and damn she's smooth now! No rough shifting, No erratic speedo, and No more P0503 codes!!!You can pull the wheel/tire and inner fenderwell inner and go in from the side or put the car up on a 4-point lift at the hobby shop and do it by Braille.
What about your local Junior College VoTech shop ???
Yeah I can't locate that part by name ANYWHERE! I even called Autozone & Advance Auto, neither of which had or knew what I was refering too, ha! Why does everything gotta be so hard....:bomb:From the looks of the FSM for my 01 STS... looks like you need an Evap purge valve.... its part of the fuel/emission system. I couldnt find the part no quick on rockauto.... look around here or call a dealer to get the part no.
