• Standard replacement grade for emission control service

Product Details

Bosch part number 13200 is part of the Bosch Engineered Oxygen Sensor line, a product family developed from Bosch’s long OE oxygen-sensor experience. This narrow-band heated sensor measures exhaust oxygen content so the engine control unit can adjust fuel delivery with the precision needed for consistent drivability and emissions performance. Bosch uses high-temperature-resistant materials and heater control strategies to maintain reliable operation under heat and vibration. For buyers searching for a Bosch 13200 oxygen sensor for Toyota 4Runner, Toyota Pickup, or Toyota Previa, this sensor is built around the original equipment style and fitment requirements of the listed applications.

This part cross-references Bosch 13200 for the same application.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Rich or lean fuel trim conditions caused by inaccurate exhaust feedback
• Rough idle or inconsistent closed-loop fuel control
• Failed emissions inspection tied to sensor response issues
• Slow sensor switching or delayed warm-up on heated O2 systems

Installation Notes and Tips

• Compatible With 1991-1997 Toyota Previa, upstream
• Compatible With 1992-1995 Toyota 4Runner, upstream
• Compatible With 1992-1995 Toyota Pickup, upstream and selected downstream applications
• Compatible With 1992-1993 Toyota Celica, upstream
• Compatible With 1993-1997 Toyota T100, upstream
• Verify connector shape, wire count, thread size, and sensor position before installation
• Inspect the exhaust bung and harness routing before tightening the flange-mounted sensor
• Use the vehicle’s exact emission configuration notes, including California emissions and bed-length details where listed
