Code Help

I recently got code p0470 and p0478 on my 2000 F-250. I replaced the Exhaust Back Pressure Sensor and cleaned the tube. Now I'm getting a code that says P700A but I can't find that anywhere....anybody got any ideas...

That's not a properly formatted code. It is powertrain related because it is a P code, but 700a is not right. Check your scanners lit, then try another scan tool.

P0703 is the lowest of the P070X's and goes up.

Generic scan tool? They don't work on the 7.3. Was it an auto part store or cheapy?

The code is actually P7A00. I'm using a Hypertech Performance Enhancer to get the codes. I got the P7A00 code at the same time I got the P0470 & P0478. All three codes are still there after changing Exhaust Back Pressure Sensor. The truck has a bad miss and NO power. The SES light stays on. Would the Exhaust Back Pressure Circuit make truck lose power.........The Back Pressure Actuator is leaking a very small amount of oil.....
