If the check engine light comes on in your 2018 Chrysler Pacifica Hybrid, it could be due to various reasons such as a loose gas cap, faulty oxygen sensor, catalytic converter issues, an EVAP leak, or a bad spark plug. Some of these problems are simple and inexpensive to fix, while others can be more complex and costly. For example, if the issue is with the gas cap, you can check if it needs tightening or replacement, which typically costs between $10 and $20. However, if the problem lies with the spark plug, replacing it could cost you around $270 to $320 in labor and parts.
If the "check engine light" pops up on your 2018 Chrysler Pacifica, it could signal a loose gas cap or a more severe problem such as a faulty O2 sensor, a significant emissions leak, or issues with the catalytic converter in your vehicle.
