This issue could be caused by a variety of things or conditions.some are minor and will still allow you to continue driving until you reach your destination while others can seriously damage your ride. No matter what caused this amber warning light on your dashboard to pop on, you have to pay attention to this issue as soon as you can. To help you figure out what\'s wrong and to save yourself a trip to a qualified mechanic, here are some of the possible culprits you should look into:
Faulty oxygen sensor
The oxygen is what monitors the vehicle\'s air-to-fuel ratio to make sure it\'s correct. It gauges if the engine is getting too much oxygen or fuel, so the engine\'s computer can balance off the issue. Over time, the oxygen sensor gets filthy or covered in oil ash, which affects its ability to determine the proper ratio of fuel and air. When the engine starts receiving too lean or too rich mixture, not only will your check engine light pop on, but your engine will burn more fuel than necessary, resulting in increase emissions. When ignored, this problem can also cause your Toyota Sienna to experience up to 40% moss of fuel economy. Your faulty sensor can also lead to a busted catalytic converter and damaged spark plugs. The code you\'ll get from the scanner will help you determine if it is indeed your oxygen sensor that\'s causing the light to turn on. If it is, then it\'s time to replace the busted unit.
Busted spark plugs or spark plug wires
When your spark plugs fail, your Sienna will experience misfires and a little jolt in its acceleration. The plugs can become bad due aging and to the high temperatures they are frequently exposed to. Bad spark wires, on the other hand, can be singled out by paying attention to your ride\'s behavior while idling. If it\'s idling louder and rougher than before, it\'s possible that the spark plug wires are the reasons your engine diagnostic light is on. Get them replaced right away to avoid experiencing poor performance and a drop in fuel economy.
Loose or damaged gas cap
Before you get too worried that something major might be going on in your ride causing the check engine light to turn on, try to pull over, get out of your car, and check your gas cap. Yes, sometimes all you need to do to get rid of that bothersome warning light on your dash panel is to tighten your gas cap. Among the possible culprits, this one\'s the easiest and cheapest to fix. Even if you need to get a new gas cap, it\'s still cheap compared to other components that may need replacement. So be thankful when you found out that the culprit is your gas cap and tighten or replace it the soonest. If you fail to do so, you\'ll lose some fuel through evaporation, causing you to make more frequent trips to the gas station.
