Camshaft Position Sensor Location and Replacement ?

I attached the location of the CMP21 sensor. As you can see it is on the back of the head on the driver side. I also attached the info on the code I assume you have.

However, I should say that if you are having an issue, it would be wise to take this to a dealer because unless the issue is as a result of something you altered on the truck, it will be covered under warranty. If the finds that you have been working on the truck, they may give you a hard time and say you caused the issue so it is always best to have them look at it and repair the issue.

Thanks for using 2CarPros.

Thank you for the info. I understand about the warranty. We are set to go on vacation on Monday and no dealer can get it in before then and they don't have any loaner vehicles available.

Totally understand. Please let us know if you need more info. It may be worth calling some further dealers or talking to the service manager but with it being towards the end of the week, it would be a tight time frame. You could also try calling the Ford customer service just to see if they would be willing to pay for a rental while your vehicle is being worked on and you go on vacation. Just to be clear, a loaner car is a dealer owned vehicle that they "loan" out while the vehicle in for service. A rental car is from a company like enterprise and the dealer pays for it and then gets reimbursed on the warranty claim when they submit that.

I used to work for Ford and now work for another OEM and they do that all the time.

Thanks again for the diagram. It was a 5 minute job and it appears to have fixed the issue. No more check engine light and the truck has full power again. FYI, the code it gave was P0345 incase anyone is wondering.

That is great info. Thanks for the update and glad you are all set for your vacation. I figured that was the code you were getting. Thanks for using 2CarPros. Come back if you need help in the future. Thanks

Truck listed above has the ecoboost engine. I have been looking all over and can't find any information close to my truck year and engine. If you have pictures or videos it would be helpful. Thank you.

Hi,

There are a total of 4 cam sensors on this engine. I have attached two pics below showing locations. Take a look and let me know if that helps. Also, if you know what sensor needs replaced, I will be happy to provide the directions / pics for doing it. If you provide the code set, I can get it from that.

Let me know.

Joe

I need to replace the camshaft position sensor (intake). I’m having trouble locating it.

Hello,

They are located on the rear of the cylinder head. There are two per cylinder bank, one intake, one exhaust, for a total of four sensors. I have included a factory description in the diagrams down below. Let us know if there is something else we can help you with.

Thanks,

Thank you.

You are very welcome. Let me know if you need anything.

Take care,
Joe

One more question...
Which are the intake sensors?

So it seems that everyone who has an issue with the Camshaft sensor can't find them. Well I believe I have found them, but would really like to make sure.

So, the check engine light would come on and off, but I never noticed any running issues. It came on and I and I had it scanned. The scan was P0365.

Two days later my truck started running rough and I couldn't go over 40-50 miles a hour. It take a long time with the key turned over to start.

P0365 Camshaft Position Sensor B Circuit Bank 1

I believe that there are two Camshaft sensors on the passenger side at the rear of the engine. 1 is more towards the direct rear and the other off to the rear passenger side.

I did replace the one at the rear and still had the issue. I put the old sensor back in and put the new one in the one off to the passenger side rear and still had the same issue.

I would appreciate some help on this. This website and you guys are invaluable.

thanks,

Hello again,

What do you mean by intake sensor?

Thanks,
Alex
2CarPros

Hi,

Bank 1 will be the passenger of the vehicle. I attached a picture below and circled sensor B. Is this the one you are referring to?

Let me know.

Joe

There are four CMP sensors, two intake and two exhaust.

Yes, that's the one. That is honestly the best diagram that I've seen. I ended up changing the one your circled and still had the problem. So, I put the old sensor back in and changed out the other one. I was trying to rule out which sensor had the issue since I didn't know which one was sensor B.

Tomorrow I will change it back out to the right sensor. My problem is that even when I changed sensor B, it did not change the way the truck ran. I unhooked the battery before changing them out.

My plan going forward is to change out both sensor and see if that fixes the issue. I have been reading about the wire harness potentially being bad.

I appreciate you taking the time to help me navigate this.

Hello again,

Yes there are. Joe should have sent some outstanding diagrams and location descriptions in his first reply. I would refer you to those, please.

Thanks,
Alex

Hi,

You are very welcome. I have a feeling that replacing the other sensor isn't going to remedy the problem. The code you have is specific to the sensor you already replaced.

Here is the actual flow chart for diagnostics related to this code. I feel bad attaching it. LOL I don't how comfortable you feel doing it, but thought it may be of interest to you. If you look at that last pic I attached, it shows a list of things that can cause this code.

_________________________________________________________

It's likely that you now hate me for attaching this. LOL Regardless, let me know what you find.

Take care,
Joe

LOL, I don't hate you!! When I read your response what I thought was that it's time to take it to the shop!!!

So, I ended up taking it to a mechanic and he hooked his scanner to it and the first code that popped up was Fuel Volume Regulator Control Circuit Code DTC P0001

The mechanic mentioned to me that the fuel issue was causing the truck to throw the camshaft sensor code DTC P0365. He reset everything and got the light off and the truck smoothed out.

So I ended up driving home without the check engine light on but the truck still had the dramatic loss in power and when I shut it off and started it the check engine light came back on.

So I think that the AutoZone's scanner did not catch the real issue. I am trying to figure out what to do from here.

I’ve been searching for hours. I can’t find it on my truck or online to show me where it is on my truck.

Good morning,

I attached a picture of the locations of the sensors. You have 4 sensors, 2 intakes, and 2 exhaust.

Why are you replacing the sensor? Was there a code? If there was, what is the code?

Roy

I can't even seem to find the correct part if I wanted to change the fuel pressure regulator just to take a stab at it.

The code was p0365.

There isn't a traditional regulator on this vehicle. It is controlled by a two fuel pump control modules. The two fuel pump control modules modulate the voltage to the 2 fuel pumps (FP) required to achieve the correct fuel pressure. Voltage for the two fuel pumps is supplied by the power relay and fuel pump control module relay. See pic 1. On the fuel rail is a FRPT sensor which signals the control module of real time pressure so the module can adjust voltage to the pumps.

Let me know if this helps explain.

Joe

Which 2 are the exhaust?

That makes a lot of sense. I wondered if it worked something like that.

So what would be the first move on this?

Okay, bank 1 is the passenger side of the engine. The sensor is the one that is closest to the exhaust manifold.

This code indicates a voltage issue with the wiring. I would verify there is 5 volts to the sensor and the return line to the ECM is not damaged or open.

Roy

At this point, I would simply start by testing fuel pump pressure at the fuel rail to see if it is within the manufacturer's specs. Here is a link that shows in general how it is done.

Here are the directions specific to your vehicle. You will need a fuel pressure gauge, but most parts stores will lend one to you with hopes of selling you a new part. lol

The attached pics will correlate with these directions.

The last pic shows pressure specifications.

Let me know what you find.

Take care,
Joe

The ones that are closest to the exhaust manifolds.

Roy

Joe let know one ever tell you that you are not the man.

Thank you for the information. Nothing I have read mentioned 2 sensors (exhaust). I had to get my OBD tool... The tool actually shows 6 DTC's the other code is P0369, it shows both the codes 3 times each.

LOL. Did you get it going again?

Joe

I have a transient code p0016 along with a turbo under boost code. It comes and goes there is no noise from the motor or timing chain. I will be driving and the truck performs normal turbo engages and runs smooth. Then i will loose the turbo the truck will run smooth though under powered. Turning the truck off and restarting often clears the symptoms for a while. I have replaced the cam sensor and located and removed the crank sensor but am having a difficult time reinstalling the new one. I cant seem to locate the opening for the pick up on the sensor. Does it seat into a hole like the cam sensor?

Okay, I posted the 369 possibilities as well.

check the connectors to all 4 sensors.

Roy

No, not yet. My mechanic is a certified diesel mechanic and suggested I take it into the dealership. He told me that his gut is telling him that its the PCM with the trouble shooting he's done.

That bums me out because I was literally planning on trading my truck in this weekend and buying another one. I am 99% sure that it falls under the warranty though.

I thought I found the PCM but not sure. ECM - Ford (GD9Z-12A650-AANP).

It doesn't fit into the same kind of recess exactly like the cam sensor, which makes it way harder to line up the bolt. It truly takes patience and you have to hold your tongue just right to get that bolt lined up perfectly. I usually put my finger in the area to feel for it to determine the location and to sum up about how far it is before I try to put the sensor in.

I attached a picture below of the PCM's location. Part number (GD9Z12A650AANP), so you have the correct number. Interestingly, the directions to remove and replace refer to it as a PCM, but under the parts, it is referred to the ECM. They are the same thing. LOL

Let me know if this helps.

Joe
