OEM Part Number(s):AFH55-M10, AFH55M10, 74-50052, 7450052
Compatibility?
1990-1994NissanD212.4L
1995-1996NissanPickup2.4L
Package Included:
One Air Flow Sensor/Meter
How To Determine If These Sensors Are Malfunctioning
DTC codes P0171/P0174 may be set due to lean fuel mixtures and P0172/P0175 may be set due to rich fuel mixtures. DTCs P0101 through P0103 may also be set in the computer memory. A scan tool can be used to monitor the MAF data parameter during engine operation.
How To Install The Replacement Mass Air Flow Sensor
1. Position MAF sensor in the vehicle. Make sure the airflow direction indicated on the sensor is toward the engine.
2. Install sensor-to-air-duct seal(s), if so equipped, on the replacement MAF sensor.
3. Connect the MAF sensor to the throttle body air cleaner ducts. If the sensor mounts directly on the throttle body, install and tighten the mounting screws to 10 ft-lb. DO NOT OVERTIGHTEN!
4. Position clamps over the air duct/MAF sensor connections and tighten. Replace the clamps if necessary.
NOTE: For the MAF sensor to work properly, the sensor/air duct connections must be airtight.
5.CAREFULLY plug the harness connector lead into the MAF sensor.
