ok

below are possible failures.

You will need a shop to hook up to an advanced scan tool and run a bay test on the evap system. that will confirm the code is active.

you are smart not clearing it. there is freeze frame data there for a tech to see when he checks the system. clearing does absolutely nothing as the issue is still there and needs to be checked.

Possible Causes

FUEL TANK PRESSURE (FTP) SENSOR 5-VOLT SUPPLY OPEN/HIGH RESISTANCE

What Customers are Saying:

I AM VERY GLAD THAT I TOOK A CHANCE ON YOUR PROBLEM SOLVING SKILLS. I WAS SUCCESSFUL IN REPLACING THE FUEL PUMP. MY TRUCK RUNS LIKE A CLOCK. IT RUNS LIKE THE DAY I BOUGHT IT. NO LUNGING FORWARD, THE TURBO REACTS THE SECOND I STOMP ON THE GAS, AND IT HAS A LOT MORE POWER AND EVEN SOUNDS BETTER TO ME. IT SAVED ABOUT $500.00 BY DOING THE WORK MYSELF. I GIVE YOU ALL THE CREDIT FOR YOUR DIAGNOSING THE PROBLEM, JUST FROM THE SYMPTONS I GAVE YOU OVER THE e MAIL. I WILL USE YOUR WEB SITE AGAIN AND REFER MY FRIENDS. THANKS SO MUCH FOR THE HELP.
