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.

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

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,

Welcome to 2CarPros.

The sensors are on the rear of the engine. There are two per side, one for the intake cam and the other for the exhaust. I have attached a picture to help you locate them.

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.

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.

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.
