Question

2014 Chevrolet Cruze LTZ 1.4L Why are do these Trouble codes mean P0171, P0106, P1101? How to fix this problem?

Answer 1

P0171 Fuel trim lean Bank 1

P0106 Manifold absolute pressure (MAP) sensor performance

P1101 Intake airflow system performance

False air, check the airflow duct from the MAF (mass airflow sensor) to the throttle body, any type of vacuum leak from the MAF to the throttle body is false air, which gets past the MAF sensor and is unaccounted for.

​ 

What you need to do is check the MAF air duct from the MAF sensor to the throttle body for any opens which will allow false air to enter the system and be unaccounted for.
