Inaccurate Speedometer in my 1995 Buick Century Special 2.2l?
If you believe that the speedometer in your 1995 Buick Century Special 2.2L is inaccurate, there could be a few potential reasons for this issue. Here are some steps you can take to diagnose and potentially resolve the problem:
- Check Tire Size: Incorrect tire size can affect the accuracy of your speedometer. Make sure that the tires on your car are the correct size as specified in the owner's manual. If you've recently changed the tires, the new size might not match the original specifications.
- Inspect Speed Sensor: The speedometer gets its information from a speed sensor, usually located on the transmission. If this sensor is faulty or damaged, it could lead to inaccurate speed readings. Inspect the sensor for any visible damage or wiring issues.
- Test Speedometer Calibration: There's a possibility that the speedometer itself is out of calibration. You might need a professional mechanic or an automotive specialist with the right tools to recalibrate the speedometer to ensure it's accurate.
- Check for Faulty Wiring: Wiring issues can disrupt the signals between the speed sensor and the speedometer. Inspect the wiring for any signs of damage, corrosion, or loose connections.
- Scan for Error Codes: Modern vehicles, even those from the 1990s, often have onboard diagnostic systems that can store error codes related to various components, including the speed sensor. Use an OBD-II scanner or visit a mechanic to check if any error codes are present.
- Mechanical Issues: Mechanical problems in the transmission or drivetrain can affect the accuracy of the speedometer. If there are issues with these components, they might need to be inspected and repaired.
- Consult a Professional: If you're not comfortable diagnosing or repairing the issue yourself, it's advisable to take your car to a qualified mechanic or automotive technician. They have the experience and tools to properly diagnose and fix the problem.
Remember that an inaccurate speedometer isn't just an inconvenience; it could also lead to legal and safety issues if you're not aware of your actual speed while driving. It's important to address this issue promptly.
2013 buick Encore Knock sensor location?
Greetings,
Based on the description from the Advanced AutoParts website, you should check the engine for the sensor. I would use a picture of the sensor to guide you in locating it around the engine area of your Buick. The item looks like a magnifying glass with no glass with bronze colored piece that lays within a black circle. You'll see what I'm talking about when you run it's name in a search engine image search.
Thank you.

How can I remove a factory lock on a 95 buick regal ODB PORT
since there is not one you do not need to.
Just about every GM in 94-95 is plagued by the "transitional" OBD 1.5.
You will need a scanner capable of this feat, that can also plug in to the ALDL connector. '94 Regal is also using the ALDL Data port. 93 is the last year of being able to use the paper clip trick to get codes out of it.
use an Actron CP 9145 with a CP 9127 cable to get it. You'll be pulling OBD 2 codes from it

On a 2002 buick century custom the horn relay under hood is what Amp fuse
Fuses and relays are two completely different things. Relays don't normally have a fuse built into them. Is this the horn fuse or the horn relay your referring to?
If it is the Relay, (a Small, square, black plastic block), take it to a good auto parts store and they be able to give you the correct one. The car will run normally without it.
If it is the fuse, ( a flat, coloured piece of Plastic with two metal 'ears'), they are usually marked with the amp rating as a number and the letter A. They are also usually colour coded having certain Amp ratings as certain colour. It is often a 15A fuse, possibly a blue one.
Where do the fuel pump wires run on a 1995 Buick Lesabre?
Hi. In a 1995 Buick LeSabre, the wiring for the fuel pump typically runs from the fuel pump relay, which is located in the front passenger door area, to the fuel pump itself, which is located inside the gas tank. The wiring is generally routed inside the vehicle, often underneath the carpeting and interior trim.
To access the wiring near the fuel pump, you will likely need to remove the rear seat. Here are the general steps to follow:
1. Remove the Rear Seat: Depending on your specific model and configuration, the rear seat may be secured with bolts or clips. Look for bolts at the bottom of the seat or clips under the front edge of the seat cushion. Remove any fasteners and lift the seat out.
2. Lift Carpeting and Trim: Once the seat is removed, carefully lift the carpeting and any surrounding trim pieces in the rear passenger area. You may need to detach plastic retainers or remove screws to do so. Take care not to damage the carpet or trim.
3. Locate the Wiring: Look for a wiring harness or conduit running along the floor or under the carpeting. This harness should lead toward the rear of the vehicle, closer to the fuel tank area. Trace the wiring until you find the connection point near the fuel pump.
4. Cut and Splice the Wiring: Once you've identified the wiring near the fuel pump, you can cut and splice the wiring as desired. Make sure to use appropriate connectors and ensure proper insulation to prevent any potential electrical issues.
It's important to exercise caution when working with electrical wiring. If you're not comfortable with this process, it's recommended to consult a professional mechanic or electrician who can assist you with the wiring replacement.
Additionally, please note that modifying the wiring of the fuel pump may have implications for your vehicle's warranty and safety. It's advisable to consult with an automotive expert or refer to your vehicle's documentation before proceeding with any modifications.
