A reluctor ring is a notched circle used in the anti-lock brake system (ABS) and the ignition system of cars. The anti-lock brake reluctor rings are located on each wheel. The distributor-less ignition, or direct-ignition, reluctor ring is mounted on the crankshaft that triggers the magnetic sensor. The ignition reluctor ring combines evenly and unevenly spaced notches that send information to the electronic control module in order to control ignition timing.Know More
A warning light will notify the car owner if the ignition reluctor ring needs to be replaced. If a car needs a new anti-lock brake reluctor ring, then the ABS system lights may flash on and off. Banging might also occur when braking at slow speeds, or the brake pedal may fluctuate.
There is no need to replace all ABS rings at once. To find the cracked ring, a mechanic uses fluorescent fluid and an ultraviolet lamp. About an hour is needed for a qualified mechanic to replace an ABS reluctor ring. Replacing the ignition reluctor ring takes a full day because the ring is connected to the crankshaft.Learn more about Car Parts & Maintenance
Reasons for a car running rough can include problems with the engine temperature or oxygen sensors, bad hoses, ignition system or timing problems, clogged air or fuel filters, and faulty spark plugs or fuel injectors. Many problems that manifest through a rough idle can be easily fixed.Full Answer >
An ignition coil is a coil in a car's ignition system that carries the 6 or 12 volts from the battery to the many volts used to spark the spark plugs in the ignition. An ignition coil is also called a spark coil, and is classified as an induction coil. All induction coils are electronic transformers that transform low-voltage pulses from the DC supply into higher voltage currents needed to spark machine engines.Full Answer >
A squeaking sound that happens when the steering wheel is turned is likely to be something faulty in the power steering system. However, if the squeaking sounds like it is coming from the front end of the car rather than directly from the steering wheel, it could be related to the suspension. A third possibility for a squeaking sound is loose steering linkage.Full Answer >
An ABS light comes on when the car computer finds a fault in the anti-lock brake system, causing the computer to deactivate that system. The car can still brake, but the wheels may lock up, causing the car to either spin or skid forward when braking.Full Answer >
