Diagnosis Before Replacement

Inspect the air filter, intake connections, sensor connector, and wiring. Check for contamination or air leaks and compare live airflow with engine operating conditions before replacing the sensor.

Installation Notes

Switch the ignition off before disconnecting the sensor. Keep the sensing element clean and untouched, secure the intake connections, and verify operation after installation. Complete any vehicle-specific adaptation procedure required by the manufacturer.
