Signs Of A Bad Distributor Rotor


While you won't see a distributor on many modern cars, they are a common component in the ignition system of older vehicles and have a variety of parts that require periodic maintenance and replacement. The distributor sends power to the correct spark plug in time with the camshaft, helping you start and run the engine. A distributor rotor is installed inside the distributor on the end of the shaft connected to the cam and under the distributor cap. As the engine runs, the distributor rotor rotates to make contact between the coil terminal and the individual spark plug wire terminals on the underside of the distributor cap. This allows voltage from the coil to flow through the rotor and to the spark plug for ignition. The rotor itself is usually plastic which can crack due to exposure to high temperatures, and the metal contact points on the distributor rotor may be subject to wear over time. This can limit continuity and prevent voltage from reaching the spark plug terminals. A damaged distributor rotor can cause the spark plugs to not receive power and stop firing, and extreme cases or failing to address an engine misfire may cause damage to your engine. Signs of a bad distributor rotor include an illuminated Check Engine light, odd engine noises, misfires, an inability to start your vehicle, or weak spark. During your inspection, check the condition of the distributor rotor body and contact points, as well as the terminals on the underside of the distributor cap. If you notice a cracked, corroded, or damaged distributor cap, be sure to replace it immediately to prevent ignition issues and misfires. It's recommended that you replace the distributor rotor and the distributor cap approximately every 50,000 miles for optimal performance, though your vehicle's manufacturer may provide a different interval. If you notice rotor damage or poor ignition system performance, the distributor rotor and cap may need to be replaced sooner than expected. Replacing spark plugs and wires as well as the distributor rotor and cap is considered part of a routine tune-up due to their exposure to high voltage, and is part of maintaining a healthy ignition system.
