TOYOTA AVALON TROUBLE CODE

Code Po353 Keeps Coming Back Everytime I Clear It Out. I Can Not Find Any Defined Answers On The Problem. Is It A Coil Or Something Else....

I Know What Po135 Is But What Is Po135pd?

I Cleared The P0135, And It Seems Like It Takes Around 45 Minutes To Come Back. No Other Codes Or Symptoms.

Camshaft Position Sensor Circuit Low Bank 1 Circuit 2? Changed The Sensor And Still Getting The Code. Can You Help Me? It Keeps Coming Back...
