Locate the accelerator cable next to the throttle assembly towards the back and top of the engine and remove the shield. Pull the retaining pins using a pair of slip joint pliers if necessary.

Remove any other accessories that might interfere with the removal of the camshaft sensor like wiring harness, spark plug retainers or engine cover, depending on your particular Ford Taurus model.

Move the fuel-injectors wiring harness off the valve cover studs as well to gain access to the camshaft sensor if necessary.

Locate the camshaft sensor around the top of the engine. For more information, see the Resources box at the bottom of this article.

Unplug the camshaft-sensor electrical connector by pressing on the lock tab and pulling the plastic connector off the sensor.

Unfasten the two sensor mounting screws using a Phillips screwdriver and remove the sensor from the engine compartment.

Installing the Camshaft Sensor

Position the new camshaft sensor in place and start the two mounting screws by hand to avoid damaging the threads.

Tighten the two mounting screws using the Phillips screwdriver.

Plug the camshaft-sensor electrical connector.

Realign the fuel injectors' wiring harness over the valve cover studs.

Install any other accessories you had to remove to gain access to the camshaft sensor like wiring harness, spark plug retainers or engine cover.

Replace the accelerator cable shield if you had to remove it. Use the slip joint pliers if necessary.

Connect the ground, battery cable using one of the wrenches to hold the terminal bolt in place and tighten the retaining nut with another wrench

It is one of two things. Crank shaft sensor, on timing cover, behind crank pulley. Or the camshaft syncronizer, or the camshaft sensor (sits on top of Camshaft syncronizer) Located on drivers side end of engine, in what used to be the home of the old type distributor.

The camshaft position sensor (CMP) on the 3.0L OHC (4 valve) and 3.4L SHO engines is a variable reluctance sensor that is triggered by a high point on the left-hand exhaust camshaft sprocket. The CMP sends a signal relating camshaft position back to the PCM which is used by the PCM to control engine timing.

The camshaft position sensor (CMP) on the 3.0L OHV (2 valve) engine is a single hall-effect magnetic switch that is triggered by a single vane which is driven by the camshaft. The CMP sends a signal relating camshaft position back to the PCM which is used by the PCM to control engine timing.

Hope helps.

it is located right below the throttlebody where the air inlet is below the wire harness

PO340 is the camshaft position sensor needs replacing.
P1400 is Differential Pressure Feedback sensor is bad.
