P0101, P0171, P0174 Codes. PLEASE HELP!


Recommended Posts

P0101- MAF Sensor. - system can't measure how much air is coming in.

P0171- too lean bank 1- not enough fuel

P0174-too lean bank 2-not enough fuel

Clean your MAF and reset. 

In a nut shell, your truck can't decide the correct amount of fuel to add because it doesn't know how much air is going in.
