Bosch 17019 Oxygen Sensor - Upstream, Upstream Left or Upstream Right

Bosch Wideband O2 Sensor for OE Fitment

Bosch part number 17019 is an Actual OE Oxygen Sensor built for precise air-fuel ratio measurement in wideband applications. It delivers fast, continuous feedback to the engine control unit, helping maintain accurate mixture control in Mercedes-Benz and Dodge Sprinter applications with upstream sensor placement.

Key Features

• Wideband A/F oxygen sensor for high-precision lambda measurement
• Heated design for faster light-off and stable operation
• Specific-fit sensor with 5-wire harness and included wiring harness
• Threaded mounting with 18 mm thread diameter and 22 mm hex size
• Oblong male connector with blade terminals and 6 terminal positions
• Robust metal housing for OE-style durability
• Overall length: 33.2 in; sealing surface to connector end: 32 in

Detailed Description

Bosch 17019 is part of the Bosch Actual OE Oxygen Sensor line, a product line focused on OE-level sensor design and calibration for modern engine management systems. Bosch pioneered the wideband A/F oxygen sensor architecture used across many late-model vehicles, and this sensor reflects that OE development with a planar pump-cell design, optimized heater control, and ceramic construction for consistent readings under changing load and temperature conditions.

Use Bosch 17019 when you need a direct replacement oxygen sensor for upstream monitoring on select Mercedes-Benz SLS AMG, SL63 AMG, CLS63 AMG, E63 AMG, CL63 AMG, ML450, S63 AMG, CLK350, CLK550, CLK63 AMG, E300, E350, E550, C230, C280, C350, E280, and Dodge Sprinter 2500 or Sprinter 3500 applications. This part cross-references Chrysler 5135667AA and Mercedes-Benz 0035427118 for the same application. Bosch 17019 is a fitment-focused replacement for vehicles that rely on wideband sensor input for precise fuel control and emissions management.

What It Helps Address

• Check engine light related to oxygen sensor performance
• Incorrect air-fuel ratio readings from a worn upstream sensor
• Rough idle, hesitation, or inconsistent throttle response tied to mixture control
• Reduced fuel economy caused by inaccurate sensor feedback
• Emissions test failures linked to faulty oxygen sensor data
