Keep the engine computer fed with accurate exhaust readings using the NTK Air / Fuel Ratio Sensor 27026, an upstream (pre-catalyst) sensor that drops in as a direct-fit replacement for the 2014-2020 Mitsubishi Outlander, 2014-2016 Mitsubishi Outlander Sport, 2014-2016 Mitsubishi RVR, 2017-2018 Mitsubishi Mirage, 2017-2018 Mitsubishi Mirage G4, and 2018-2022 Mitsubishi Outlander PHEV.
An air/fuel ratio sensor measures the oxygen content of the exhaust ahead of the catalytic converter and reports the actual air-fuel ratio to the ECU so it can adjust fuel trim.
If a failed upstream air/fuel ratio sensor is the cause of a stored fuel-trim code, rough running, or reduced fuel economy, this replaces it; diagnose the underlying cause before replacing, as those signs can have other sources.

Manufacturer part number 27026.
This part cross-references / interchanges with the following part numbers:
What does this air/fuel ratio sensor do?
It measures the oxygen content of the exhaust ahead of the catalytic converter and reports the actual air-fuel ratio to the engine computer, which uses that signal to adjust fuel trim.
Where is this sensor installed?
It is the upstream (pre-catalyst) sensor. On some applications this is the upstream left or upstream right position, so confirm the correct location for your vehicle.
Which vehicles does the 27026 fit?
It is a direct-fit for six Mitsubishi models: 2014-2020 Outlander, 2014-2016 Outlander Sport, 2014-2016 RVR, 2017-2018 Mirage, 2017-2018 Mirage G4, and 2018-2022 Outlander PHEV.
What are signs this sensor may need replacing?
Signs that may point to it include stored fuel-trim or sensor codes, rough running, or reduced fuel economy. Diagnose the cause first, since these symptoms can have other sources.
What numbers does this sensor interchange with?
It cross-references 234-5180, 234-5182, 1588A274, 1588A307, 1588A363, 1588A459, and 1588A467. The manufacturer part number is 27026.
