A common issue with the 2006 Lexus ES330 is when the Check Engine Light comes on along with the P0171 and P0174 codes. The first code indicates "System Too Lean (Bank 1)", which means there is an excess of oxygen in the exhaust detected by the O2 sensor in Bank 1. The second code is triggered for the same reason, but it's detected by the upstream O2 sensor in Bank 2. Symptoms include decreased fuel efficiency, lack of power, and hesitancy when accelerating. This problem is often caused by a dirty mass airflow sensor, which is recommended to be replaced instead of cleaned. The estimated cost typically ranges from $140 to $150 for parts and $35 to $45 for labor.
I'm encountering a problem with code P0766 related to the D shift solenoid. What steps should I take to address this issue?
