Can a condenser fan motor cause check engine light to stay on?

Yes, a condenser fan motor can cause the check engine light to stay on if it affects the vehicle's cooling system or engine temperature. If the motor fails, it can lead to overheating, triggering sensors that activate the check engine light. Additionally, if the vehicle's computer detects issues related to the air conditioning system, it may also illuminate the warning. However, the check engine light can be triggered by various other issues, so a diagnostic scan is recommended for accurate identification.
