The Buick Century has about 22,000 miles. The Service Engine Soon light has appeared on the dash. The instruction manual is not clear. What would you recoomend? What might cause the light to appear?
View 15 Replies2000 Buick Century Custom with 140K miles: Service Engine Light came on. Re;placed gas cap, light still on. Took to dealer who replaced HO2 sensor, light still on. Took to dealer who found no problem but charged $100 for looking. Light still on. Took to dealer who said it needed two major parts. Light still on. Took to another mechanic who could find nothing wrong. Light still on. Is there hope?
View 8 RepliesMy 2000 Buick Century has an issue that whenever it rains really hard, after driving a while the ABS, Trac Off, and Service Vehicle Soon lights come on. I am assuming that part of the electrical connections are getting wet and causing the lights to come on. When there is no rain, obviously the lights don't come on. It's only done it one other time and it did it today. I was just curious what to do to fix it, before I jump into looking at all electrical connections which we all know can be hard to diagnose. By the way, the car has 64,000 miles on it if that makes any difference.
View 2 RepliesThe car died on me the other day at a stoplight but started up again (It resisted for a sec but then caught). Now it's taking a bit to start and sounds very faint when it finally catches and the turn over is slow. I'm no mechanic but I can replace parts. I'm just wondering if it's the fuel pump or injectors, maybe low fuel pressure. I haven't had a chance to do anything to it. Where to start?
View 3 RepliesI'm trying to get my 2000 Regal to pass inspection, but every time I have it serviced and need to drive it for approx. 100 miles before the emmissions test, the service engine soon light comes back on. Can a bad gas module in the gas tank be the culprit? My gas gauge has not worked for several years and it didn't cause the service light to come on before, but the mechanic said that is the only 'code' that comes up on diagnostics.
View 8 RepliesCode 0341 (cam sensor?)On my way home epc light flashed about 5-7 times and message saying service engine. 111,000 miles and just had intake manifold replaced and plugs and coils not to long ago. I have been feeling a slight hiccup at cruising speed and twice my gti has just shut off while driving. New fuel filter as well. I searched the forum and didn't come up with anything specific. Can I just replace the cam sensor or is there more to it than that.
View 1 Replies2006 Buick Lacrosse, CXL, 78K miles. 6 months ago, the check gas cap message came on. The gas cap was replaced. The message is still on. Soon after, the engine light came on as well. The Buick dealer said (without running a diagnostic or looking at the car) we needed to replace the catalytic converter and it would be expensive! Had 2 diagnostic tests run - one at a garage and one at an auto parts shop. No codes were detected.
Whenever the car is close to its 3k oil change, an "'oil low" message appears. The oil has never been low, it's an annoying message to get the oil changed. As the gas cap/engine light came on shortly before its 75K mile check, could this be the same case?
The car runs great and there has been no change in gas mileage.
Replaced sensor, light stays on.Removed sensor, grounded the probe, light goes out.Replaced antifreeze, bled system twice, no air or oil.Getting desperate. Removed and cleaned battery to body ground strap.Removed and cleaned battery to engine ground strap.Today found out there is no error code in the OBC but the light is still!
View 1 RepliesI have a 2001 Buick Century that started making a noise from what seems to be the engine. It sounds like a jet engine when I accelerate. The noise is still there when I cruise, but it evens out. It is loudest when going between 40 and 50mph. The car is not overheating, and other then the noise it drives fine. My husband at first thought it sounded like the catalytic converter had been stolen, but he rarely knows what he is talking about. What could it be?
View 2 RepliesRan scanner and it showed codes C1215, C1226 and C1233. We checked the passenger front and found the wire to the sensor hanging off. It was damp inside so we dried it as much as we could. We reconnected the wire and tested. The light still on. We ran the scanner again, Only one code came up C1233. The book says ( Right front wheel speed circuit open or shorted)

I have a 2003 Buick Century 3.1L. The airbag light goes on randomly. I realize that it is supposed to go on momentarily after I start the engine. Sometimes the light will stay lit for one or more drives and sometimes it will stay off for one or more drives. I have checked the fuse; it is good. I have tried smacking the airbag on the steering and the dash...the light remains lit. I have seen a bundle of wires on the back side of the fuse box and am not sure whether I should try to trace the fuse wire back to both locations or what to do next. Is there some trick of the trade like a reset button and what do you think I should try next?
View 2 RepliesI have a 2004 Buick Century and the small window that indicates what gear you are in, on the dash, is very dim. All other dash lights are bright and working good. Is this the bulb and what sort of job is it to change it.

View 2 RepliesI have the GM shop manual and I have gone through the flow chart for an engine which cranks but does not start. I have confirmed that there is fuel pressure and spark, but the injectors do not fire when cranking. I have gotten to the final troubleshooting step of disconnecting the crank angle sensor connector, jumping A and B terminals on the connector, and momentarily grounding the jumper with a test light. The injectors fire as confirmed using the GM injector test light (in place of an injector). The flow chart conclusion is that the crank angle sensor is bad or misadjusted or the connector is making a bad connection. I have replaced the sensor twice and adjusted it using the GM adjustment tool. The connector terminals appear clean and undamaged. 1989 Buick Century 3.3 liter ...

Ok, got a 99 Buick Century that is a cantankerous old hag. It doesn't like to start sometimes. naturally when i really need to get somewhere. The security light blinks at me for a while, goes solid, then i cycle the ignition and hope it will start. It happens with multiple keys and remote start(which has been removed multiple times because each mechanic thinks that will magically fix it). No rhyme or reason, it sends no code, the local buick dealership couldn't figure it out. I think its my security computer. what is the easiest/cheapest diy solution besides get full coverage and leave it in the ghetto with the keys and hope it ends up on cops? battery is fine, it starts normally most of the month, just maybe a handful of times a month it won't. Starter I believe is still good as well, and gets voltage when it starts. Fuel pump audibly works all the time.
View 4 RepliesLast month I changed the oil and filter in my 1992 Buick Century with 264000 miles. I used a name brand (Citco) of the correct oil, 10W-30, API Service SN. I bought the oil on sale at a local supermarket. Now, I hear a loud tapping sound from the engine, especially when it's cold. It dosen't sound as loud after warm-up. The tapping increases in frequency when I rev up the engine. I don't intend to keep this old car much longer, but is this problem an immediate concern? Could it be a valve problem? Could it Could I have bought some bad oil with a conterfeit label? Other than this noise, the car runs okay.
View 3 RepliesI had my ABS and Traction Control system checked a few times for buzzing sounds and ABS warning light coming on occasionally. My mechanic assured my all the speed sensors and connections were good. I recently noticed there was uneven tire wear on the right front tire. Could a severe misalignment of the front wheels cause the ABS warning light to come on?
View 11 RepliesI have a '97 Buick Century. I noticed the smell of coolant, and the "Low Coolant" light flashed on the dashboard. However, according to the temp gauge on the dashboard, the car was at normal temperature. I pulled over and opened the hood. The coolant in the overflow tank (not the radiator) was boiling, and sputtering out.
I took the vehicle to a nearby shop, where they said it needed a new "Coolant Level Switch." They told me they put a new one in and did a coolant flush, and sent me on my way.
About a mile down the road, the "Low Coolant Light" came on again. I pulled over and found that there was ZERO coolant in the engine. I filled it myself, and continued driving. Over the next few days, I checked the coolant every day and it stayed normal. I drove a bit, but never more than a few minutes, so the car didn't have a chance to overheat.
Then, today, I drove it a good distance for the first time since the original incident. After a few minutes of driving, I smelled coolant and pulled over. The coolant in the overflow tank was once again boiling and bubbling out. What it might be?
I have 89 buick Century custom cpe had it out on the highway last night and the Batt light started to flash intermittently. after a little while it calmed down. Had it out running around today and no problem. what should I check besides the battery terminals?
View 4 RepliesI have a 98 Buick Century, with about 250k miles on it. Recently when I first start the car and drive a few miles the temperature gauge keeps rising until it is in the red zone and a warning light comes on. When I pull of to the side of the road after a bit it begins to slowly drop and I can begin to drive again. The gauge will then normally stay a bit above halfway for the remainder of the trip, the gauge has sometimes done a bit of jumping around between 3/4 and half sometimes though. The only work that I have had done on it recently is to have some work done on the ac system.
