2011 Nissan Titan Check Engine Light Codes

In Mesa, AZ, drivers trust Larry H. Miller Nissan Mesa to decode and resolve check engine alerts on the 2011 Nissan Titan. The most common codes our certified technicians see include P0135–P0167 (oxygen sensor faults), P0171/P0174 (lean condition), P0420 (catalyst efficiency), and P0101 (mass airflow sensor). Left unresolved, these conditions can reduce fuel economy, increase emissions, and lead to costly downstream damage such as catalytic converter failure.

Our technicians document findings and present cost-effective options that highlight immediate savings—fewer repeat trips, better fuel economy, and extended engine life.
