Common Reasons for Check Engine Lights in Toyota RAV4:

There are possible factors which could cause this problem. Some of the most common causes are given below.

Sensor Breakdown:

The sensor, also known as the oxygen sensor, estimates how much oxygen is required in the exhaust system to improve the air-fuel blend. A broken or faulty sensor can increase fuel usage and emissions and harm the exhaust system. You will know that the oxygen sensor is broken when you feel rough idling, poor acceleration, and, of course, the engine light.

Broken or Faulty Gas Cap:

A loose or damaged gas cap is a typical but fixable reason for the check engine light. The gas cap seals keep up with the pressure of the fuel system. A loose cap can increase fuel fume spills, which can also set off the engine light. To fix the issue, you can either tighten the pipe or replace it with a new one.

Catalytic Converter Issues:

The catalytic converter reduces harmful gas emissions by changing exhaust gasses into less unsafe gasses. A damaged or rusty catalytic converter can cause poor engine execution, increase fuel usage, and increase emissions. Symptoms include a smell like a spoiled egg and slow engine execution.

Mass Airflow Sensor Issues:

The mass airflow (MAF) sensor estimates how much air enters the engine and decides on the appropriate air-fuel combination. A failing MAF sensor can cause bad mileage, the engine slowing down, and a blinking engine light. Indications of a faulty or damaged MAF sensor include poor starting, delay during speed increase, and a blinking engine light.

Spark Plug Issues:

The spark plug is very important for an engine and is mostly used for combustion. Loops and faulty ignition coils also cause the check engine light, reduce power, and increase emissions. The common symptoms are poor cancellation and rough idling. You can fix it by replacing it or cleaning it up.

Troubleshooting of Check Engine Light:

To troubleshoot the issues with the engine light, you have to follow the process below step by step.

Step 1:

If the gas cap is damaged or loose, fix it accordingly or replace it if needed. Also, investigate the engine straight for any loose connections, damaged hoses, or other noticeable issues.

Step 2:

Connect the OBD-II scanner to the diagnostic port, which is generally under the dashboard. Now, Turn on the car and follow the OBD scanner’s guidelines to read and the diagnostic means to translate the possible trouble code. You should use the scanner’s manual or a web-based data set to decipher the codes. This will provide you with a list of potential issues.

Step 3:

If you find simple issues like a spark plug or gas cap issues, then you can fix them yourself by replacing them, but anything complex then that should be fixed by a professional mechanic. 

Step 4:

If you have an OBD scanner, you should use it to get the code for that particular issue. Then, take that code to a mechanic, who will properly fix it. After that, you won’t face or see the engine light again for a long time.
