Bosch 13362 Oxygen Sensor - Upstream or Upstream Right

Bosch Oxygen Sensor for Mazda and Kia

Bosch 13362 is a specific-fit, narrow-band heated oxygen sensor built for upstream applications on select Mazda and Kia vehicles. It delivers air-fuel-ratio feedback to the ECU for stable closed-loop control, accurate combustion management, and lower emissions.

Key Features

• Specific-fit Bosch Engineered Oxygen Sensor for direct application matching
• Narrow-band heated O2 sensor with 3-wire design
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Rectangle female connector with pin terminals
• Wiring harness included for the listed application
• Steel-finish metal housing for high-temperature service
• Part number 13362 for easy lookup and ordering

Product Line Details

Bosch Engineered Oxygen Sensor products draw on Bosch OE development in oxygen sensing technology, including narrowband designs that respond quickly and support closed-loop operation. Bosch uses ceramic sensing elements, controlled heater operation, and heat-resistant materials to maintain consistent signal quality under thermal and vibration stress.

Detailed Description

Bosch 13362 is a standard replacement oxygen sensor for upstream locations on 1994-1998 Mazda MX-3, 1995-1998 Mazda Protege, and 1995-1997 Kia Sephia applications. It is also listed for the 1994 Mazda MX-3 upstream right position with California Emission System. This Bosch oxygen sensor is engineered for precise switching-type signal output, helping the engine control module maintain the correct air-fuel ratio during normal driving and warm-up conditions. If you are replacing a worn upstream sensor on a Mazda Protege, Mazda MX-3, or Kia Sephia, part number 13362 provides the correct fitment details for the listed vehicles.

What It Helps Address

• Check engine light caused by a failing upstream oxygen sensor
• Rough idle or unstable fuel control from inaccurate O2 feedback
• Increased emissions from delayed or incorrect sensor response
• Poor closed-loop operation during warm-up or steady cruising
• Driveability issues tied to degraded narrow-band sensor output

Installation Notes and Tips

Verify the vehicle year, make, model, and sensor position before installation. This part uses a threaded mount, 18 mm thread size, and a 3-wire heated configuration with a rectangular female connector. Confirm harness routing and connector style against the original sensor before replacement. Bosch 13362 is listed for upstream and upstream right positions only on the applications shown.

Quality Assurance

Bosch has more than five decades of OE oxygen sensor development behind this design, and the Bosch Engineered Oxygen Sensor line is built to OE-proven standards for accuracy and durability in aftermarket service. This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.
