Bosch 18071 oxygen sensor for the 2011-2022 Toyota Corolla 4-cylinder 1.8L and other vehicles reads the air-fuel ratio continuously across the full lambda range and passes it to the ECU. As a wideband sensor, it gives the ECU more detailed readings than a traditional switching sensor, which supports fuel efficiency and lower emissions.
- Planar pump-cell wideband design for high-precision air-fuel ratio measurement
- Reaches operating temperature in under 7 seconds for quick closed-loop control
- Metal housing, integrated heater element and TSP coating to resist vibration, corrosion and contamination
- Built to withstand exhaust streams up to 1,880°F

A worn wideband sensor can show up as a check engine light, a rough idle or higher fuel use. Before you replace the sensor, rule out an exhaust leak near it, damaged wiring and a loose connector, since each of those can also upset the readings.

Frequently Asked Questions
Is this the right Toyota Corolla oxygen sensor for a 2011-2022 model with the 4-cylinder 1.8L?
Yes. Bosch 18071 is listed for the 2011-2022 Toyota Corolla 4-cylinder 1.8L, which takes one sensor. For any other car, use the "Vehicles it fits" section.
Does the Bosch 18071 come with a wiring harness?
Yes. Bosch 18071 comes with its wiring harness, and the direct-fit connectors are made for quick installation.
Is this Bosch premium oxygen sensor a wideband type?
Yes. It is a wide-band sensor with 4 terminals, an M18 - 1.5 thread and a 22 mm hex.
Is anti-seize already on this Bosch O2 sensor's threads?
Yes. Conductive anti-seize is pre-applied on the threads of this oxygen sensor.
Does a check engine light mean this wideband oxygen sensor is failing?
Not by itself. A worn sensor can light the lamp, with a rough idle or higher fuel use, but other faults can too; a shop can read the codes and test it.
