There are few things that can startle you more than driving your Honda Odyssey and suddenly noticing that your check engine light is flashing. As if this was not bad enough, you realize that your car is also shaking, causing anxiety and concern to increase.
You may be tempted to ignore the problem or think that your car will eventually work fine, but the best advice we can offer you is not to wait. Here in this article, we will discuss some options that might help you diagnose the problem and solve it before it becomes worse.
Why Honda Odyssey Check Engine Light Flashing And Car Shaking?
The check engine light on your Honda Odyssey serves as an indicator of problems related to the vehicle’s engine, transmission, or emissions control system. Usually, when the check engine light is on, the issue is not urgent, but if it is flashing, that’s a whole different story.
When the light is flashing, it indicates a severe problem that needs immediate attention. Shake is usually associated with engine malfunction, which is why these two problems often go hand in hand.
1: Check the Gas Cap – Make Sure It’s On Tightly
One of the most common reasons for a check engine light to turn on and flash in a Honda Odyssey is a loose gas cap. Check to see if the gas cap is on tightly. Tightening the cap may make the check engine light go away. If the cap is loose or missing, buy a new one to replace it.
2:Troubleshoot Ignition Issues – Check for Faulty Spark Plugs or Wires
Another reason why your Honda Odyssey’s check engine light is flashing, and your car is shaking could be due to ignition issues. When spark plugs or wires of vehicles are faulty, it can also cause engine misfires and shake. If you notice any corrosion, wear, or breakage of the spark plugs or wires, have them replaced as soon as possible.
3: Inspect the Fuel System – Look for a Clogged Fuel Filter or Low Pressure
If the gas cap is not the problem and it’s not the ignition system, then it may be related to the fuel system. A clogged fuel filter or low fuel pressure can cause your Honda Odyssey’s engine to misfire and the vehicle to shake. Fuel filters are typically replaced every 30,000 miles, so it might be time to replace yours.
4: Replace the Oxygen Sensor – If Necessary, Replace it with a New Part.
The check engine light in your Honda Odyssey may also be flashing due to a faulty oxygen sensor. If this is the case, the sensor needs replacing. A faulty oxygen sensor can also cause the engine to misfire, along with causing your car to shake.
5: Examine the Air Intake System – Verify That Everything Is Secure
Besides the oxygen sensor, other components in your Honda Odyssey’s air intake system can be loose or have issues that could be contributing to the flashing check engine light and shaking car. Check that the air filter, hoses, and clamps are tight and secured as per the manufacturer’s instructions.
Conclusion:
When it comes to your Honda Odyssey, a shaking and flashing check engine light is an alarming sight. While some drivers may choose to ignore this issue, this is not the wisest decision. Ignoring a flashing check engine light can lead to significant engine damage and a hefty repair bill. If your Honda Odyssey’s check engine light is flashing, it is essential to address the issue as soon as possible. Whether it’s a fuel, ignition, oxygen sensor, or air intake system issue, getting to the root of the problem is the most effective way to resolve it.
