Hello .. If you will copy past this link into your web browser it will take you to a jpeg image showing right where your temp. sensor is located ... Sincerely Richard
All 2003 Ford vehicles were shipped with vacuum line routing diagrams printed on a sticker, which should be affixed inside your engine compartment. It is important that you use THAT diagram, as vacuum routing varies widely from vehicle to vehicle depending upon options and regional configuration.
The EGR is on the Differential Pressure FEedback system. The EGR is located on top middle of the backside of the engine It is round and has a hose attached to it.
it doesnt hold pressure the pump primes it straight away but on teh end of the fuel rail is a vacumn operated valve that allows the build up of pressure required and if the vacumn pipe or the diaphgram is perished then thats your problem
this vacumn line is to open the flaps on the A/C inside the car so it will run from the inlet manifold to somewhere on the heater/blower housing ,but where i cant help you with ,sorry none of these cars here in spain so i never seen one
The trick is to snake your arm down the back, ajacent to the maifold pipe, and unplug the wiring harness. Should be a 10mm socket to unscrew the bolt that holds the sensor in place. Once the screw was out it was easy to pull the sensor out and rush to Auto Zone and get a new one. Reverse the process in putting the sensor in.
