What does this code mean?

code p 0401 is the EGR va;ve but the principle reasons for problems are EGR valve
EGR solenoid
hose blockage and wiring
code p 0460 refers tois the fuel tank level sensor--low input===causes ---wiring short to ground --fuel level sensor--ECm

bank 1 sensor 1 lean code. Check vacuum lines first. Could be egr leak also. Most vacuum lines run on the back side of the engine on these. Most common fail is the PCV 90 degree elbow. On the passenger side.

Many issues are simply resolved by updating the ECM on board computer, with a truck this year I wold check to see if there are any recalls.

• P0340 - Camshaft position sensor circuit malfunction.
  
• P0457 - Evaporative emission control system leak detected (fuel filler cap loose/off)
  
  There is a bulletin #0398 posted on 05/12/2003 for P0457 - Malfunction indicator lamp (mil) illumination with diagnostic trouble codes p0442, p0455, p0456, p0457, p1442 or check fuel cap lamp illuminated with diagnostic trouble code p0457.

I'd suggest checking with your local dealer, as it may be a fix that is covered by the dealer.

P0442 FORD - Evaporative Emission System Leak Detected Small Leak

Possible causes- Missing or loose fuel cap
- Incorrect fuel filler cap used
- Fuel filler cap remains open or fails to close
- Foreign matter caught in fuel filler cap
- EVAP canister or fuel tank leaks
- EVAP system hose leaking
- Fuel tank leaking
P0136 - O2 Sensor Circuit Malfunction Bank 1 Sensor 2
Possible causes- Rear Heated Oxygen Sensor Bank 1 harness is open or shorted
- Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Faulty Rear Heated Oxygen Sensor Bank 1
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

P0141 FORD - O2 Heater Circuit Bank 1 Sensor 2

Possible causes- Faulty Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit fuse
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit open shorted to ground
- Heated Oxygen Sensor (H2OS) Bank 1 Sensor 2 circuit poor electrical connection
- Faulty Engine Control Module (ECM)

P0460 Ford Fuel Level Sensor Circuit

check fuse 50 7.5 amp trouble code po460 under the dash if fuel gauge works

could be a loose or corroded connection at fuel snedr/pump assy in top of fuel tank

P0460 FORD Description The fuel level sensor is mounted in the fuel level sensor unit. The sensor detects a fuel level in the fuel tank and transmits a signal to the Powertrain Control Module (PCM).

It consists of two parts, one is mechanical float and the other side is variable resistor. Fuel level sensor output voltage changes depending on the movement of the fuel mechanical float.

change the fuel sensor.is near the gas pump on the gas tank.cold joints on the sensor.isnt repairable you must change the sensor.
