2007 Ford F-250 Super Duty Lariat Questions & Answers
What does po135, p1131, and p0305 mean on a ford
PO135 = Upstream Heated Oxygen Sensor Heater (HTR 11) circuit (Bank #1)
P1131 = Lack of upstream Heated Oxygen Sensor (HO2S 11) switch, sensor indicates lean (Bank #1)
P0305 = Cylinder #5 Misfire detected
It looks like you have two separate issues happening. Bank 1 would be the left side of the engine if you were standing in front of the truck looking at the engine. The "upstream" oxygen sensor will be on the exhaust pipe coming from the bank one side of the truck IN FRONT of the catalytic converter. From the codes, it appears that the upstream sensor has gone bad, but the oxygen sensor behind the catalytic converter, or "down stream" is fine.
The misfire on cylinder 5 on the right side of the engine, 2nd one from the front, could be something as simple as a fouled spark plug or a coil malfunction.
To identify if it is a bad coil, swap the #5 cylinder coil with another coil, and see if the misfire follows the relocated coil.

Power Point in 2004 F-250
Look in your manual for the Power Distribution Box reference in Roadside Emergencies. It should be located under the hood on the driver's side. My 2002 Explorer has two power points on the center console and the 20A fuses in the Power Distribution Box for them are number 7 and number 9. They cost $3.99 each at AutoZone. The cigar lighter fuse under the dash is unrelated.

Your thermostat is stuck closed. You need to replace it with a new one. If you follow the large hose to where it goes into the motor, the thermostat is mounted to the motor and the hose is actually attached to the thermostat. Usually easy to replace. Get one at any automotive parts supply. I hope this is helpful to you. If so, please take a sec to rate me. Thanks!Don

Check the fuel delivery system. Everything on a 6.0 is dependent on the high-pressure oil system to actuate the injectors. If there is a fault in the system, the ECM will not allow the motor to start or run. CHANGE OIL RELIGOUSLY! I'd start with verifying the IPR and IPC are operating correctly. Depending on the year, these are located in different locations. In my 03' they are located under the heat shield below the turbo at the rear of the motor. Need a cool motor to inspect cause you've got to lay on it to access from the top.
