Code Help
Have a 2002 Ford F-150 with a 4.2 liter and 5 speed manual transmission.
Lately it has been running rough at times and dying at idle. I scanned it.
Just put my Auto Xray scanner on my truck, here is a list of codes it is throwing.
P0340 Cam Position Sensor Fault
The rest are Lean engine codes on both banks.
P1336
P1131
P1151
P0170
P0174
What could be causing these?
Any and all help would be appreciated.

Codes 170, 174,1131,1151 are all responses to the same fault.
Clear the fault cause and they all will clear.
The 340 is the PCM can't see the signal from the sensor.
The 1336 is saying the crank and cam position sensors are out of sync.
With all the codes, it tells me the cam position sensor is the root cause of all this codes.
Meaning the engine is running lean because the cam position sensor is not controlling fuel injection properly causing a lean fuel condition.
The other codes are just the responses to the main fault.
Service for the cam position fault, first.
On a V6 it is the device on the top front of the block where a distrubutor would normally be on that motor.
It has to be set in place according to a spec once removed, for correct fuel timing to occurr.
Good luck.
