2017 Kia Forte: Check Engine Light and Car Shaking

Introduction

The 2017 Kia Forte is a popular compact sedan known for its reliability and affordability. However, like any other vehicle, it can experience occasional issues. One common problem reported by Forte owners is the illumination of the check engine light accompanied by car shaking. This issue can be caused by various factors, ranging from minor glitches to more serious mechanical problems.

Causes of Check Engine Light and Car Shaking

1. Spark Plug or Ignition Coil Issues

Worn-out or faulty spark plugs or ignition coils can lead to misfires, causing the engine to run rough and shake. This can trigger the check engine light to come on.

2. Fuel System Problems

Clogged fuel injectors, a failing fuel pump, or a faulty fuel pressure sensor can disrupt fuel delivery, resulting in engine hesitation, shaking, and the check engine light.

3. Vacuum Leaks

Leaks in vacuum hoses or gaskets can allow unmetered air to enter the engine, altering the air-to-fuel ratio. This can cause engine shaking and trigger the check engine light.

4. Transmission Problems

Issues with transmission components, such as slipping gears or worn-out clutches, can cause the car to shake while driving. These problems can also result in the check engine light illuminating.

5. Exhaust System Issues

A damaged or clogged exhaust system can restrict exhaust flow, causing engine performance loss, shaking, and the check engine light.

6. Engine Mounts

Worn-out engine mounts can allow excessive engine movement, leading to shaking. This can also trigger the check engine light if sensors detect abnormal vibrations.

Solutions

1. Check Spark Plugs and Ignition Coils

Inspect spark plugs for wear or damage and replace them if necessary. Also, check ignition coils for any signs of cracking or damage and replace faulty ones.

2. Diagnose Fuel System Issues

Use a fuel pressure gauge to check fuel pressure and identify any problems with the fuel pump or fuel injectors. Clean or replace clogged injectors and consider fuel system cleaning.

3. Inspect for Vacuum Leaks

Examine vacuum hoses and gaskets for leaks. Listen for hissing sounds or use a smoke machine to locate and seal leaks.

4. Check Transmission

Have a qualified mechanic inspect the transmission for any issues. Worn-out clutches or slipping gears may require repairs or replacements.

5. Inspect Exhaust System

Check the exhaust system for any damage or clogs. Repair or replace any damaged components to ensure proper exhaust flow.

6. Replace Engine Mounts

If engine mounts are worn out, they need to be replaced. This will reduce excessive engine movement and minimize shaking.

Conclusion

The check engine light and car shaking in the 2017 Kia Forte can be caused by various issues. By understanding the potential causes and solutions, you can diagnose and address the problem effectively. Regular maintenance and prompt repairs can help prevent these issues from recurring, ensuring a smooth and reliable driving experience.
