Yes. A severely clogged air o r fuel filter can disturb the air-fuel ratio, causing the ECU to detect irregularities. This can trigger the Check Engine Light, produce error codes related to oxygen sensors o r MAF sensors, o r even push the car into limp mode. Such symptoms should not be ignored and filters should be checked immediately.
