I don't know anything about cars, is this price reasonable for an air flow sensor? Provided by a Nissan dealership

2014 Nissan Altima with around 90k miles

Cause FOUND P0101 FOR THE MASS AIR FLOW SENSOR. NEED TO REPLACE THE MASS AIR FLOW SENSOR, CLEAN THE THROTTLE BODY AND RELEARN THE IDLE.

Correction REPLACE THE MAF SENSOR, CLEAN THROTTLE CHAMBER AND RELEARN IDLE.
