SilverCaddy Posted March 17, 2008 Report Share Posted March 17, 2008 Hey, love the forum. i was thinking of getting rid of my '99 STS actually until the forum answered alot of my questions about overheating and oil consumption. i do still have a couple of problems with the car though and need a little help. 1. When the car comes up to operating temperature, the steering sticks and it gets hard to turn. 2. the service suspension light comes up on the dash but no codes are stored. can someone point me in the right direction with this? 3. the gas gauge doesn't work properly. if the tank is filled, it'll show full but after that it just hovers around 1/2 to 3/4 of a tank. Any help is greatly appreciated. Thanks in advance Link to comment Share on other sites More sharing options...
JimD Posted March 17, 2008 Report Share Posted March 17, 2008 ....1. When the car comes up to operating temperature, the steering sticks and it gets hard to turn.Is there some condition other than engine operating temperature you can relate to a loss or reduction of power assist? Because engine temperature ain't the problem here. 2. the service suspension light comes up on the dash but no codes are stored. can someone point me in the right direction with this?How are you reading the codes?, are you using a "scanner". I ask because most of the made-in-China hand held scanners only read "P" codes and you will have a "C" code stored when you see the SERVICE SUSPENSION SYS message. 3. the gas gauge doesn't work properly. if the tank is filled, it'll show full but after that it just hovers around 1/2 to 3/4 of a tank.Again there is a good chance there is a code stored to guide you to the problem. The good news is if the fuel level sensor has failed, you do not have to drop the fuel tank to replace the pump/sender assembly.

When the car comes up to operating temperature, the steering sticks and it gets hard to turn. Assuming the power steering fluid isn't low, I would nevertheless change the fluid by disconnecting the line and allowing the fluid to pump out and then refile with fluid and maybe a conditioner. Maybe the fluid is contaminated, air, or the fluid is too thick or moisture/water infiltrated? Link to comment Share on other sites More sharing options...

Have you tried this method of displaying codes? http://www.caddyinfo.com/readingcodes.html I figured that engine temp wasn't the problem, the only thing i know is that it's only after the car's been running for a while that the steering gets stiff. it's fine when the car is cold though I'm reading the codes with a OBD2 handheld scanner i bought at autozone. the fuel sensor that says gas is low doesn't come on anymore at all. if i don't get to a gas station it'll just run out without warning me. i'm new to the forums, i'm starting to look into that now Link to comment Share on other sites More sharing options...

SilverCaddy Posted March 18, 2008 Author Report Share Posted March 18, 2008 Have you tried this method of displaying codes? http://www.caddyinfo.com/readingcodes.html thanks, i just tried the on board diagnostic and got a RSS C1761 code, which is a Road Sensing Suspension problem Link to comment Share on other sites More sharing options...
JimD Posted March 18, 2008 Report Share Posted March 18, 2008 C1761 - Right Front Position Sensor Input Fault This the reason for your SERVICE SUSPENSION SYS message. Check behind and inboard of the RF wheel and should find a small link rod that connects the lower control arm to a chassis mounted "black box" which is the RF position sensor. Be sure the link rod is attached. Follow the electrical harness from the position sensor to the inside of the engine compartment where it connects to the chassis harness. If the connectors and cabling check out OK, you could have a failed sensor. Clear all codes and see if the code returns. Jim Drive your car. Use your cell phone. CHOOSE ONE !

SilverCaddy Posted March 19, 2008 Author Report Share Posted March 19, 2008 I looked at the rods, and everything checks out so I assume it's a sensor problem. Also, I went back to my onboard diagnostic and got a RIM B0532 code. I can't find my book though, does anybody know what it is? Link to comment Share on other sites More sharing options...
steve6 Posted March 19, 2008 Report Share Posted March 19, 2008 I have this problem with my power steering, The power steering fluid in my car had turned to like sludge, yours is probably the same, try changing the fluid, you might have to do it a few times. I never got the problem to fully go away, its a biotch to monover in our works under ground parking, haha. Im pretty lazy though, didnt do a good change. DTC B0532 Fuel Sensor Shorted To Ground or Open. Wires might be broken or shorted, I think there is a cover under the trunk mat you can have a look under, maybe the wires shorted through. It will show you the top of the tank. C1761 - Right Front Position Sensor Input Fault - sensor probably need to be changed, I had to change one on my rear last year. I just (borrowed) one from the wrecking yard =) Link to comment Share on other sites More sharing options...
stu_pidasso Posted March 20, 2008 Report Share Posted March 20, 2008 So, I have a 2000 SLS with many of the same problems. Lately with all the potholes, I get a "service stability system" warning. I also have a big oil leak (about a quart a week) plus check engine light for misfire. My car looks like a million bucks and is completely loaded, but I bought it because it is a Caddy. What point do you say "It's only worth 6500 trade in?" sorry to be a downer, but I feel your pain. Link to comment Share on other sites More sharing options...
WarrenJ Posted March 21, 2008 Report Share Posted March 21, 2008 Regarding the fuel gauge problem, you might find this thread interesting: http://www.cadillacforums.com/forums/cadil...ender-unit.html Regards, Warren There is no means of avoiding the final collapse of a boom brought about by credit expansion.
