Why Is the Check Engine Light On in My Suzuki Alto Lapin?

I noticed that the check engine light has turned on in my Suzuki Alto Lapin. I suspect it might be related to a sensor, but Im not sure which one is causing the issue. Could it be the oxygen sensor, mass airflow sensor, o r something else? How can I diagnose and fix this problem?

The check engine light CEL turning on in your Suzuki Alto Lapin could be triggered by a number of sensor-related issues. The most common sensors that can cause this light to come on are:

Oxygen Sensor O2 Sensor: A malfunctioning oxygen sensor can send incorrect data to the engine control unit ECU, leading to poor fuel combustion, reduced fuel efficiency, and higher emissions.

Mass Airflow Sensor MAF: If the MAF sensor is faulty, it can misread the amount of air entering the engine. This can cause the engine to run rich too much fuel o r lean too little fuel, impacting performance and fuel economy.

Throttle Position Sensor TPS: A malfunctioning TPS can cause issues with idle speed, acceleration, and engine performance, which can trigger the check engine light.

Camshaft o r Crankshaft Position Sensors: These sensors monitor the position of the camshaft o r crankshaft to synchronize fuel injection and ignition timing. If they malfunction, the engine may misfire o r fail to start.

Solution:

Diagnosis: The best way to identify the issue is to use an OBD-II scanner to read the trouble codes from your ECU. The code will point to the specific sensor causing the problem.
Repair: Depending on the sensor identified, you may need to replace it. Common repairs include replacing the oxygen sensor, mass airflow sensor, o r other components based on the codes.
