Keep the engine reading its exhaust accurately with the Bosch Oxygen Sensor 16167, an upstream (pre-catalyst) sensor that drops in as a direct-fit replacement for the listed applications — including the 2004-2008 Chrysler Crossfire, 2001-2005 Mercedes-Benz C240 and C320, 2003-2006 Mercedes-Benz CLK500, and 2003-2008 Mercedes-Benz SL55 AMG. See the Buyer's Guide tab for the full list of covered vehicles.
An upstream oxygen sensor sits in the exhaust ahead of the catalytic converter and measures the oxygen content of the exhaust gas, feeding that signal to the engine control unit so it can trim the air-fuel ratio.
If a failed upstream sensor is the cause, replacing it restores an accurate exhaust-oxygen signal to the ECU. Signs this sensor may need replacing include an illuminated check engine light and reduced fuel economy — diagnose the cause before replacing, as these symptoms can have other sources.
Interchange: Manufacturer part number 16167.
Is this an upstream or downstream oxygen sensor?
It is cataloged as the upstream (pre-catalyst) sensor, in the right-side position, for the listed applications.
What does this oxygen sensor do?
It measures the oxygen content of the exhaust ahead of the catalytic converter and sends that signal to the engine control unit, which uses it to adjust the air-fuel ratio.
Which vehicles does the Bosch 16167 fit?
It fits 14 applications, including the 2004-2008 Chrysler Crossfire and various 2001-2008 Mercedes-Benz models such as the C240, C320, CLK500 and SL55 AMG. See the Buyer's Guide tab for the full list.
Will replacing this sensor fix my check engine light?
If a failed upstream oxygen sensor is the cause, replacing it can clear the related code. These symptoms can have other sources, so diagnose the cause before replacing.
What is the manufacturer part number?
This is Bosch manufacturer part number 16167.
