SOURCE: Reverse Wire

If only life was that simple. Seriously you should check out a Haynes manual. The wiring colours change from year to year and even then you can't be absolutely sure.
Point in question - I had a number of issues with wire colours that didn't match with what they were supposed to be even in the manual. A little detective work later and I discovered that Ford had used the following years wiring looms in my car so I was looking at the wrong diagrams.

2003 ford expedition check engine light is on. It is reading a p405 code which is the egr sensor. I have change the sensor and the pig or electrical code twice . I brought the sensor from ford.


This DTC says nothing about changing the sensor or the connector or pig tail ! It's a circuit voltage low code
P0405 - DPF EGR Sensor Circuit Low Voltage Detected See DTC P1400 Problem with wiring or PCM !
P1400 - DPF EGR Sensor Circuit Low Voltage Detected The EGR monitor checks the DPF EGR sensor signal to the PCM for low voltage. The test fails when the average voltage to the PCM drops to a voltage less than the minimum calibrated value.
  • DPFEGR circuit short to GND
  • Damaged DPF EGR sensor
  • VREF short to GND
  • Damaged PCM
A DPF EGR PID reading less than 0.2 volt with the key ON and engine OFF or running, indicates a hard fault.

Where is injector relay located?


2001 Ford Expedition is not equipped with an "injector relay". The fuel injectors are supplied power by the Powertrain Control (PCM) Relay.

HINT: Check for battery voltage on the RED/LIGHT GREEN wire at any of the injectors with the key in the ON or RUN position. If battery voltage is present, the PCM relay is working.

2003 Ford Expedition - service engine soon light is on


Generally this turn on when have any problem with the emission sensors; to know excalty what fault code there, make one scanned the PCM in autozone or autoshop with OBD Codes Reader.

With this code number we could send aditional details.

Hope helps (remember to rate and comment this).
