Car sensors — O2 sensors, parking sensors, ABS sensors and temperature sensors.
Car sensors monitor the engine, exhaust, brakes, wheels and other systems, and a faulty sensor can cause a check engine light, poor fuel economy, rough running, ABS warnings or parking problems. O2 (lambda) sensors measure oxygen in the exhaust, parking sensors help with reversing, ABS sensors measure wheel speed and crankshaft and camshaft sensors control engine timing. Check the part number and car model before ordering, and read fault codes with an OBD2 scanner to identify the faulty sensor. Replacing a faulty sensor can restore performance and fuel economy.
Ignition: ignition system.
