How does trip odometer work? Most odometers work by counting wheel rotations and assume that the distance traveled is the number of wheel rotations times the tire circumference, which is a standard tire diameter times pi (3.1416). If nonstandard or severely worn or underinflated tires are used then this will cause some error in the odometer. How can odometer readings be tampered with? The readings are tampered with by either removing the odometer and winding back the numbers or by connecting the drive cable to another (newer) odometer. However, strict laws have now been put in place to avoid odometer...

Is speed sensor the same as ABS sensor? The ABS sensor is also called the wheel speed sensor or ABS brake sensor. Since all the wheels do not turn at the same speed, the ABS sensors report the speeds of all the four wheels to the ECM, based on which the ECM determines if the wheels are locking up. When to replace a bad wheel speed sensor? 1. ABS Light is illuminated on the dashboard Since the wheel speed sensor also monitors the anti-lock braking system on your car, it's common for the ABS Light to illuminate when the sensor...

When to know if you have an internal engine leak? If your oil is dark brown or amber, and your coolant shows no signs of oil mixing, but you still think you may have a possible internal engine oil leak, top off the oil to the full line on the dipstick, then check your oil level every 500 miles and document your findings. Why does my car make a ticking noise when I change the oil? Once an engine runs low on oil to the point where the engine makes noise, it's usually too late; the damage is done. Here...
