BodybyFisher posted a topic in Cadillac Deville, Eldorado, Seville, Fleetwood, Sixty SpecialI am working on a 95 Eldorado, it has a P024 current code, the speedometer does not work and it has a check engine light. My friend is trying to sell the car and I am going through it to put it in saleable condition. The VSS or Vehicle Speed Sensor is located in a tough spot to get at sort of behind the right engine mount support in the top of the right tranny output shaft. I needed to get the engine mount support out of the way to make room to get at the 10mm bolt that holds the VSS in. I supported the car on a bottle jack, removed the right dog bone, put a bottle jack under the transmission and removed the engine mount support bolts including the 4 nuts on the rubber mount. Gently jacked the tranny up to make room to remove the support and pulled it out. Here is what the area looks like I took the VSS (vehicle speed sensor) out and tested it with an ohm meter, and got 0 (zero) resistance, as if it were open. The new VSS had a resistance of 1500 ohms, so I knew I found the problem. Here is the VSS sensor: Not a bad job, a little tight. I got a little nervous with how high I needed to jack the tranny to gain room to get the support out. If I wanted to play it safe, I would probably remove the axle next time, so as to NOT pull the inner CV mount out of its seat. All good though. The FSM states that a current P024 in the event of a failure, 1) turns on Service Engine Soon MIL, Cruise Control is disabled, TCC is disabled, The PCM will substitute a calculated vehicle speed based on the transaxle input speed and the current gear commanded (gear ratio), transaxle freezes transaxle in current gear and torque management is disabled. The only problem that I noted was that the tranny did not appear to go into OD, the TCC was not engaging. The check engine light is now out. Hope this helps.
Hi all. First off Happy Easter to all. I have a 2000 Catera and it has my head spinning right now, See title. To start. Sometimes the car will not start, you turn the key on and it turns off like you shut the key off. I figured this out. There is a fuse block on top of the battery, all 4 fuses were corroded and losing connection. I have to get 4 new fuses but for now I cleaned all connections and the fuses are all supplying full voltage now. The Speedo, odometer are not working at all. There were 3 codes related to VSS circuit So I replaced the VSS and inspected the VSS plug. Now the codes are gone but the speedo and odometer are still not working. The ABS, TCS lights are both on, not sure if it is related to above The radio, trunk release, on star, fuel door, traction button all do not work at all. The radio doesnt even display anything, and the trunk is useless because there is no keyhole. I checked all fuses, at least I think I did, I took care of the ones in the block at the battery, and there is no blown fuses in the box next to the battery. I found another fusebox below the steering wheel and all were good except one 30 amp heated seat fuse. I replaced the fuse and it did not pop. I was told that when it dries out that things start to work again. She said that when the radio works, the on star, trunk, fuel door, and traction all works. But when it rains or gets wet everything quits working. Today I spent almost 5 hours on the car and found out that the rear carpets are soaked. I removed the drain plugs at the rear floors and let it drain. I pulled all the sill trims and the rear seat. I found 2 things that make me worry. 1. at the right front kick panel there is a module and there are several wires tapped into the wires to the module. I dont know if this is for the on star or what but All connections were intact. 2. There is a harness under the rear seat. 5 wires maybe that look to have gotten hot. Dont look damaged but there is a groove in the matting on the floor and it is all black like the harness melted the groove. I dont expect any miracles here but am just looking for a step in the right direction. I also worry about a fire hazard when there are so many electrical problems, and water may be involved. I only have 1 code now that my scantool shows, constant, as soon as you clear it it comes right back, U2108, unsure of the definition. Thanks all for reading
