Bosch 13544 right oxygen sensor for the 2003-2004 Toyota Corolla 4-cylinder 1.8L and other vehicles reads the air-fuel ratio in the exhaust and reports it to the ECU. This Bosch O2 sensor is a narrow-band, heated switching-type unit.
A check-engine light, rough idle or poor fuel economy can be a sign of a worn sensor, and damaged wiring can look much the same. With the engine off and cool, look over the sensor wiring and connector for cracked or melted insulation before you replace anything; a shop can read the codes and test the signal.
