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
The ignition system of an automobile draws electrical current from the battery, increases the voltage using an induction coil, and distributes the current to the spark plugs to ignite the fuel-air mixture. The distributor and an ignition-timing system ensure that current flows to the correct cylinder as fuel enters the system, keeping the engine firing efficiently.Full Answer >
A crankshaft sensor has two purposes: to help a vehicle's ignition system produce a spark and to signal the fuel system to inject gasoline into the engine's cylinders. Without the crankshaft sensor, the engine cannot continue to run.Full Answer >
An ignition switch works by turning the car's ignition system on and off. It is operated by an ignition key that flips it on and off. This switch is located on the car's steering column or dashboard.Full Answer >
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 >
