Subaru Forester Oxygen Sensor – OEM 22690AA420

Overview

A new oxygen sensor for the Subaru Forester, referenced to OE number 22690AA420. The oxygen sensor monitors exhaust gas and feeds the mixture correction signal back to the engine computer; when it wears out you get a check engine light, rising fuel consumption, rough running and a failed emissions test. Because Subaru wagons and SUVs make up a large share of the New Zealand fleet — and because a failed oxygen sensor is one of the most common fault codes on any older vehicle — this is a high-frequency repair part with predictable demand. It is supplied as a complete sensor with its connector and is a direct screw-in replacement for the original unit.
