Bosch 13775 Oxygen Sensor - Downstream, Downstream Left, Upstream or Upstream Right

Bosch Validated Oxygen Sensor 13775

Bosch Validated Oxygen Sensor 13775 is a narrow-band heated O2 sensor built for precise air-fuel-ratio feedback to the ECU. It supports stable combustion control and emissions management across changing engine loads, temperatures, and driving conditions.

Compatible With 2005-2007 Chrysler Pacifica, 2006-2007 Dodge Dakota, 2006-2007 Dodge Durango, 2006-2007 Mitsubishi Raider, and 2007 Chrysler Aspen applications listed below.

Product Details

Bosch 13775 uses a switching-type sensing element to report oxygen content changes quickly and accurately to the engine control unit. Bosch developed this sensor family from its original thimble design and later planar narrowband technology, focusing on faster light-off, improved lambda accuracy, and quicker closed-loop operation. For Chrysler Pacifica, Dodge Dakota, Dodge Durango, Mitsubishi Raider, and Chrysler Aspen fitments, this sensor supports consistent feedback control in upstream and downstream positions where specified.

This part cross-references Mopar 56028999AB for the same application.

What It Helps Address

• Faulty oxygen sensor readings that trigger check engine lights
• Delayed closed-loop fuel control after startup
• Unstable air-fuel mixture control during normal driving
• Emissions test failures related to sensor response or accuracy
• Rough combustion behavior caused by aging narrow-band sensor output

Installation Notes

Verify the listed position before installation: Fits 2005-2006 Chrysler Pacifica, upstream; Fits 2007 Chrysler Aspen, downstream; Fits 2007 Dodge Dakota, downstream; Fits 2006-2007 Dodge Dakota, upstream right; Fits 2007 Dodge Durango, downstream; Fits 2005-2006 Dodge Dakota, downstream left; Fits 2006 Dodge Durango, downstream left; Fits 2006-2007 Mitsubishi Raider, upstream right; Fits 2007 Mitsubishi Raider, downstream; Fits 2006 Mitsubishi Raider, downstream left. Confirm connector shape, wire count, and thread size match the original sensor before replacement.

Quality Assurance

Bosch backs this oxygen sensor with more than five decades of OE development and aftermarket supply experience. The sensor uses advanced ceramic elements, optimized heater control, and high-temperature-resistant materials to maintain consistent operation under thermal and vibration stress.
