Check Engine Light On? A Guide to Mobile Oxygen Sensor Replacement in Malaysia

The Sniffer in Your Exhaust: The O2 Sensor

What to Do When You Suspect an O2 Sensor Problem

• Don't Panic at the Check Engine Light: A steady (non-flashing) Check Engine Light is a notification, not a critical emergency. It means the ECU has detected a fault, but the car is usually safe to drive for a short distance.
• Monitor Your Fuel Gauge: A noticeable increase in fuel consumption is a strong corroborating symptom of a bad O2 sensor.
• Get the Code Read: The only way to know for sure what the problem is is to have the ECU's fault codes read with a professional diagnostic scanner. A code like "P0135" points directly to an O2 sensor circuit malfunction.
