hello everyone I have a 2011 ford f150 w 3.5 7L
its giving ma these 2 codes
6 months now they have been on and off now on all the time

 

Have you googled the codes to see what they are?

 

P0016 - Crankshaft Position - Camshaft Position Correlation (Bank 1 Sensor A)


Symptoms

Symptoms of a P0016 will or may include:

• Malfunction Indicator Lamp (MIL) illumination
• The engine may run but with reduced performance
• The engine may crank but not start
• The engine may exhibit a rattle near the harmonic balancer indicating the tone ring is damaged
• The engine may start and run, but poorly

Causes

Causes may include:

• Timing chain stretched, or timing belt skipped a tooth due to wear
• Misalignment of timing belt/chain
• Tone ring on crankshaft slipped/broken
• Tone ring on camshaft slipped/broken
• Bad crank sensor
• Bad cam sensor
• Damaged wiring to crank/cam sensor
• Timing belt/chain tensioner damaged

 

P0299 Ford

Turbo/Supercharger Underboost
– The ECM has detected an error between the expected versus actual exhaust backpressure

Probable Cause[s]

Faulty Injector Control Pressure (ICP) sensor
EGR system fault
Engine mechanical condition -Low oil pressure
Faulty Turbo/Supercharger


Symptoms

Symptoms of a P0299 DTC may include:

• MIL (Malfunction indicator lamp) illumination
• Reduced power output from engine, possibly in a limp mode
• Unusual sounds from the engine/turbo

There would likely be no other symptoms.
Potential Causes

Potential causes of a P0299 turbo underboost code include:

• Intake (induction) air restriction or leak
• Failed or damaged turbocharger (sticking, binding, etc.)
• Faulty boost/charge pressure sensor

Faulty injector control pressure (ICP) sensor (Ford)

• Low oil pressure (Ford)
• EGR system fault (Ford)
• Variable geometry turbocharger (VGT) actuator (Ford)
• VGT vanes sticking (Ford)

I done lots of reading in all of the forms but fte is wear I go for advice the boys over in 7.3 form know there stuff and are a nice bunch of guys so I come to see what I can find out before I jump in to this this code and other code can they be related

 

I would start with the crankshaft position sensor. Check all the wiring.


Also check all the wiring to the PCM.


did you check all fuses under hood and in the kick panel or wherever they are putting the fuses In the cab?


Also the P000 is usually because of a communication error..I think you figured that one out already.

 

When you push the throttle a long time nothing happens, no speeding up. Then suddenly turbo sets in and when you release the throttle is some kind of gurgle noise

 

I think you are going to have to take it in. At least for a diagnosics.
