Fix Poor Fuel Economy and Eliminate Check Engine Lights
Is your vehicle suddenly consuming significantly more fuel than usual, idling rough at traffic lights, or suffering from sluggish acceleration? Is there a persistent yellow Check Engine Light illuminated on your dashboard? These are textbook symptoms of a failing exhaust oxygen sensor (O2 sensor). This
100% Genuine Perodua replacement rear lower oxygen sensor (Sensor Ekzos) monitors the oxygen levels in your exhaust gases after they pass through the catalytic converter.
[1, 2, 3, 4]
Leaving a faulty O2 sensor unaddressed prevents your engine control module (ECU) from correctly calculating the air-fuel ratio. This leads to an overly rich fuel mixture, which robs your engine of efficiency, increases toxic emissions, and can quickly overheat and ruin your expensive catalytic converter.

Key Features & Benefits
- Optimizes Fuel Consumption: Restores exact air-fuel ratio measurements to the ECU to return your vehicle to its factory-spec eco-driving fuel efficiency.
- Banish Check Engine Lights: Clears O2 sensor/catalytic efficiency system codes (such as Bank 1 Sensor 2 faults) to turn off dashboard warning lights.
- Premium Factory NTK Core: Built with high-purity ceramic elements and a heavy-duty internal heater to deliver rapid, accurate voltage responses under extreme exhaust temperatures.
- Direct 4-Pin Plug & Play: Features the exact factory-standard 4-pin black female socket connector and specific wire lead length for a seamless, drop-in replacement.
