Bosch 13198 oxygen sensor for the 1993-1995 Toyota 4Runner 4-cylinder 2.4L and other vehicles sends air-fuel-ratio readings from the exhaust to the engine computer. This upstream, heated, narrow-band sensor helps the ECU hold stable combustion and keep emissions down.
- Switching-type narrow-band sensor that gives the ECU air-fuel-ratio feedback
- Integrated heater element in a metal housing with TSP coating to resist vibration, corrosion and contamination
- Built to withstand exhaust streams up to 1,880°F
- Reaches operating temperature in under 10 seconds for quick closed-loop control
