Bosch Oxygen Sensor P/N:16643
Give the engine computer continuous, high-precision air-fuel readings with the Bosch 17200 Premium Wideband A/F Oxygen Sensor, a Bosch sensor for the upstream position. It is listed for many models from one make, among them the 2019-2023 Mercedes-Benz Sprinter 1500, 2010-2023 Mercedes-Benz Sprinter 2500 and 2010-2022 Mercedes-Benz Sprinter 3500. See the Buyer's Guide tab for the full list and engine details.
Bosch pioneered the first wideband A/F oxygen sensor with the planar pump-cell design, and it has supplied OE manufacturers for more than 50 years. If a failed upstream sensor is behind a check engine light, rising fuel use or rough running, this sensor replaces it. Diagnose the fault first, because other problems can cause the same symptoms. Bosch covers its oxygen sensors with a 1-year, unlimited-mileage warranty on non-commercial passenger cars and light trucks.
Which vehicles does the Bosch 17200 fit?
It is listed for many Mercedes-Benz models, including the 2019-2023 Mercedes-Benz Sprinter 1500, 2010-2023 Mercedes-Benz Sprinter 2500 and 2010-2022 Mercedes-Benz Sprinter 3500. See the Buyer's Guide tab for the full list.
Is this Bosch O2 sensor a wideband or a switching sensor?
It is a wideband A/F oxygen sensor. It gives the ECU continuous air-fuel ratio readings across the full lambda range, which is more detail than the rich/lean signal of a traditional switching sensor.
What does the upstream position mean?
An upstream oxygen sensor sits in the exhaust ahead of the catalytic converter. The ECU uses its air-fuel reading to adjust fueling.
How quickly does it reach operating temperature?
Bosch states that its wideband A/F sensors reach operating temperature in under 7 seconds. That gives the ECU a fast signal for closed-loop control after a cold start.
What are signs an upstream oxygen sensor may need replacing?
Common signs include a check engine light, higher fuel use, rough running or a failed emissions test. These can have other causes, so diagnose the fault before replacing the sensor.
