No real symptoms yet other than check engine light comes on then a few days later goes off. Back on, and off for last month. I get code p0016 Crankshaft Position, Camshaft Position, Correlation Bank 1, Sensor A. If I can find the sensor to replace, I figure it is a cheap fix even if it turns out to be wrong as the diagnostics to be more specific is a lot more money. But I don't know where the sensor(s) are? Not all Ford 3.5Ls seem to be the same, especially the F150. Mine is a 2013 MKT ecoboost.

Hello,

I have included both a diagram and removal and installation instructions for your vehicles Camshaft Position Sensors(CMP) in the diagrams down below. I hope this helps, and let us know if there is anything else we can do for you.

Thanks,
Alex

One question, which sensor is indicated as bad or do I need to replace both? Correlation Bank 1, Sensor A is not referenced on the image or elsewhere. This is very much appreciated.

These images together show even more camshaft position sensors, now 4 instead of 2. And none correspond to the reading I provided. I'm more confused than ever.

Hello again,

There are four camshaft position sensor. Your engine is a Dual Overhead Cam (DOHC) 24 Valve engine (4 valves per cylinder. In this arrangement you a have two cylinder banks, each cylinder has two intake valves(1 camshaft) and two exhaust valves(1 camshaft). Camshaft 1, 1 would be bank 1(Intake), camshaft 1, 2 would be bank 1(exhaust). Bank 2 would be 2, 1 and 2, 2 respectively. I have included an exploded engine diagram to help illustrate in the diagrams below.

Thanks,
Alex

I guess I'm not making myself clear. Comments are very frustrating since no immediate feedback to each other orally and in the sense that no diagram and no cross reference so far indicates which side of the engine is bank 1, i.E, camshaft 1. Once I have a point of reference, your previous comments should help me identify which specific sensor is causing the bad reading. It is my understanding that cylinder #1 is on bank 1. As I sit in the driver's seat, is MY left side Bank 1? I am speculating that cylinder #1 is closest to the fan blade and on the right side and that would also be in bank #1. If that is the case, then the sensor is also on the right side. Now I have to figure out which one on the right side is Sensor A. Exhaust or intake doesn't = Sensor A.

Am I correct on the location of bank#1?
If so, which of the two sensors is Sensor A using the same point of reference as I sit as the driver seat?

Oops, I meant right side as I sit in the driver's seat is where I would find bank 1.

Hello again,

Okay I have included a cylinder arrangement diagram in the diagrams below.

Thank you,

I have tried every way I know to ask you and you don't answer the question. Which of the two sensors on bank 1 is A? You continue to avoid that question. Don't get me wrong, I appreciate it but I asked the same question over and over and I'm very close, you never answer it. How do I identify the specific location of that sensor?

"Code P0016 indicates that a discrepancy has been detected between the timing of the crankshaft and the intake camshaft sensor (of engine bank 1) that exceeds 10-degrees at idle. Note: The “A” identifies the intake camshaft, which is located to the intake side of the cylinder head. “Bank 1” denotes the engine bank that contains the number one cylinder." Okay I have a link from Sensor A to the intake camshaft. And you did state it was the intake camshaft. I can't tell from the images you sent which is intake and which is exhaust. I'll presume that that intake camshaft for cylinder #1 (sensor A) would be located to the far right and the exhaust camshaft (sensor B) would be just to left of that but still on the right side of the engine. Is that correct?

If I can put my 2 cents, sensor A is on the same side as cylinder 1. But the P0016 can be caused by low or dirty engine oil which does not allow the camshaft actuators to work correctly causing the code.

Here is a guide so you can see how the system works:

Also, this guide will walk you through an oil change with the location of the oil filter below:

Check out the diagrams (below). Please let us know what you find. We are interested to see what it is.

Ken, is anyone reading what I am writing? There are two camshafts on bank 1 and two sensors, one is A for the intake and one is B for the exhaust. We established where cylinder 1 and Bank 1 was and also that the A sensor for that bank was on the right side, but so is the B sensor. The oil is fresh and is not the problem, not that I know for sure that faulty connections and wiring and maybe something worse isn't the problem. I pretty much give up getting an answer to the specific location of the A sensor and will replace both A and B sensors on the right side as I sit in the driver's seat, i.E, if Ford won't tell me.

Sensor A is closest to the intake manifold.

Hey MkT,

Did you ever replace the sensor and did it indeed take care of the code? I'm curious if it turned out to be the prelude telltale to a timing chain replacement? I have a 2013 MkT Ecoboost as well with 90,000 and I'm having the exact same symptom.

The engine light went out and stayed out. I remained worried and sold it. I gave the new owner about $1,500.00 - $2,000.00 off list and advised of the possibilities. In hindsight, I probably should have replaced all the sensors myself. Still, the risk remains and Ford/Lincoln substantially, but quietly, changed that engine. 2 chains IIRC or maybe 3, and stronger supporting parts and chain. I think they also went full synthetic instead of a blend for engine oil. Good luck.
