A very common mistake when diagnosing the P2198 code is automatically replacing the sensor or component mentioned in the code description without first testing it. Electrical issues, wiring damage, or vacuum leaks are frequently the true cause. Always use a multimeter and live data scanner to verify component failure before spending money on parts.
