Keep your engine's air-fuel control accurate with the Walker Products Oxygen Sensor 350-64035, an upstream (pre-catalytic-converter) unit that installs as a direct-fit replacement for the listed applications, including the 2013-2022 Acura ILX, 2015-2020 Acura TLX, and 2012-2019 Honda CR-V.
Mounted in the exhaust ahead of the catalytic converter, an upstream oxygen sensor measures the oxygen content of the exhaust gas and reports it to the engine control module, which uses that feedback to trim the air-fuel ratio for closed-loop operation.
Fitment: 2011 & 2014 Honda CR-Z; 2012-2015 Honda Civic; 2012-2015 Honda Crosstour; 2012-2019 Honda CR-V; 2013-2022 Acura ILX; 2013-2017 Honda Accord; 2014 Honda Insight; 2015-2020 Acura TLX; 2015-2020 Honda Fit.

Is this an upstream or downstream oxygen sensor?
It's an upstream sensor, mounted in the exhaust ahead of the catalytic converter to monitor exhaust oxygen for closed-loop fuel control.
What does this oxygen sensor do?
It measures the oxygen content of the exhaust gas and signals the engine control module, which uses that reading to adjust the air-fuel ratio.
Which vehicles does it fit?
It's a direct-fit replacement for applications including the 2013-2022 Acura ILX, 2015-2020 Acura TLX, and 2012-2019 Honda CR-V. See the Buyer's Guide tab for the full list.
What are signs my oxygen sensor may need replacing?
A lit check engine light, rough idle, or reduced fuel economy can signal a failing sensor. Diagnose the cause first, since other faults produce similar symptoms.
Does it fit both years of the Honda CR-Z?
This listing covers the 2011 and 2014 Honda CR-Z. Confirm your specific year and model in the Buyer's Guide tab.
