2009 Defender 90 Puma 2.4 HT Baltic Blue

Mass Air Flow Sensor 2.4 Puma.

Hi. I have a 2.4 puma engine and it keeps bringing the the engine light on with a fault code that points to the mass airflow sensor. The air filter is new and the sensor is new but the problem still exists. Any help would be much appreciated. Thanks.

Also if not already done, clean the connection with electrical contact cleaner spray.
