Code off Death P0340 camshaft position sensor circuit.
1999 4.2L V6 ford econoline E150 work van 126000 mils
I replaced a lot off pats: all OEM parts: camshaft position sensor circuit &Synchronizer (no damage) + alternator + crank sensor, Ground the motor & frame from the battery, tested the wire for single is good, fuel filter new oil change. Good plugs & wires

i clear the code many off time, unplug the battery & unplug the PCM keeps coming on in 3-5 mils.

The van has a hard time taking off it loose power, (it gose po po po) i have to let go off gas & press it again to take off, it dosed every time i came to a stop, if i keep a starry speed it we lose power it fine like i dropping in to a gear.

if i unplug the camshaft position sensor, the van runs & drives it's the same thing on starry speed gut not on the take off.

Any one head this problem!!!

If the sensor. wiring and connections are good, it may be the PCM. OBD-II Trouble Code: P0340 Camshaft Position Sensor Circuit Malfunction

I Fix the Problem it was theEGR pressure sensor. Some ford have the aluminum EGR pressure sensor which they rust inside, that coats the computer to thru the P0340 code. Now they use plastic EGR pressure sensor to avoided that problem.

Glad to hear that you got it fixed. Thanks for the update.
