How to fix 1997 Honda Passport code p0102?

Answer 1

clean the mass air flow sensor with sensor cleaner . you can buy it at auto parts store for about 7-8 dollars . ask them to show you where the sensor is located . before you start up the car after cleaning the sensor , unplug the battery for about 5-10 minutes to clear the computer. try this before paying 100 dollars for a new sensor . make sure your air filter is clean or buy a new one for about $16.00 . worked for me.
