    Walker Products 250-21016 oxygen sensor for the 1989-1994 Subaru Justy 3-cylinder 1.2L measures exhaust oxygen to report combustion efficiency. This Walker Products oxygen sensor is made for its specific application and upstream position, and it gives the ECU the diagnostic feedback it expects.

    • Measures exhaust oxygen to help fine-tune the air-fuel mixture for fuel economy
    • Monitors exhaust gases to help reduce pollutants
    • Electrodes made of a gas-permeable platinum layer
    • Electrode coating protects against contamination and erosion from combustion residue and exhaust particulates

    Quick facts

    • Part: Walker Products 250-21016 oxygen sensor
    • Fits: 1989-1994 Subaru Justy 3-cylinder 1.2L
    • Position: Upstream
    • Condition: New

    A failing sensor can show up as a poorly running engine, higher fuel use, more exhaust emissions or a lit malfunction indicator light. The wiring harness and connector can be behind these signs too, so find the cause before you buy a sensor.
