The Camshaft Position Sensor (CMP) on the 4.7L V - 8 engine is bolted to the front side of the right cylinder head. Disconnect the sensors connector. Take out the bolt that holds the sensor in place. Lightly pry out the sensor being careful not to break it. Clean out the hole and install the new sensor( put a little oil on the new sensors o-ring to help installation).

If you still have a cap rotor and ignition wires, it's inside the distributor. If not, it is the part where the distributor used to be (center rear of the engine behind the intake manifold)

What's the odometer reading?
Is there a third party alarm install?
Is there any spark to the plug?
Test the neutral safety switch by pressing on the brake,move gear lever to neutral "N" then start the engine.
Check for excess free play on the linkage.
(moving parts between gear lever to transmission)
Have a helper for view the reverse lights.
Shift the gear lever to reverse and check the reverse lights.
If the light does no come on then the neutral safety switch is bad.
For vehicle with over 140,000 miles,it's wise to inspect the engine and transmission mounts.
A loose transmission mounts will have more free play and wear out the transmission linkage.
Please do these test and let me know the result on reply.

Camshaft Position Sensor Circuit Malfunction
What does that mean?
This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.
