I have swapped the motor from a 09 f150 into my 06 f150 both motors are 5.4 3valves but the 09 is the revised version with different head design for the spark plugs. It is running like crap and it was suggested to me to check to see if the motors have different reluctor wheels on the camshaft or crankshaft. Can anyone look up the part numbers or be of some assistance?

 

Which PCM did you use? I would think you would have to have the one from the 09.

 

PCM is from the 06. There is a guy on here that did this swap and he used his 06 also. Dealer says I should use the 06 also.

 

Interesting. I would think that the 09 engine had design changes that are not programmed into tho 06 PCM.

 

Any codes?
Check to make sure any wires didn't get pinched?
Firing order correct on the cops?
Connections secure?

 

The 09 PCM doesn't control the transmission, it has a separate TCM - so you do need to use the 06 PCM.

 

Ok, that makes sense.

 

Dealer spent 9 hours on diagonostics. I have another 5 or 6 on the same thing. We tested everything and the deal did too. They came back with a bad motor but something doesnt add up. Compression test shows normal but leakdown shows pressure loss on the passenger side. cyl 1 =190 cyl 2= 190 cyl 3 =175 cyl 4 =145. They are saying rings or valve seats. As everything they can see under the valve cover appears to be working correct. Truck has no power at all. and a mild loss on 2 cylinders should run better then it does. That is why I asked about the reluctor wheels. No codes except transmission when you try to drive. It will not shift out of 1st.

 

You say it runs like crap. What is the computer saying? What are the fuel trims on it? Is it misfiring?

Seems like putting the next gen engine is not a plug and play sort of swap.

 

Computer is not reading any codes at all. There is a guy on here who swapped it right in. From what I was told it is not misfiring it is just way down on power. I didn't realize it was the wrong motor until it was too late as they had pulled the old motor already.

 

Just cause there are no codes, doesn't mean there isn't lots of data that can be extracted from the computer using a scanner. Would be interesting to see what the computer is doing in response to the new motor.

 

I have a scanner that data logs. It is way beyond anything I know about. If I can figure it out I will download the file and post it. I just have to pick up the truck from the dealer which has a $420 bill for a non running truck. As you can guess it is not high on my bill list!

 

Did a mechanic do the swap for you? Did you bring the motor or did he procure it? I would think that if a mechanic did the work he'd be at fault. Of course if you bought him the motor then you are at fault.

 

It is really not a matter of whos fault at this point. The dealer is saying the compression on 2 cylinders is down. That would cause the motor to run bad. It seems like it has no power at all. I figure they are wrong. I am thinking it is the reluctor wheel on the crankshaft or the cams that is causing the issues. I really need someone to look up the part #'s for the reluctor wheels on a 2006 and a 2009 and tell me if they are different.

 

You have a leakdown test showing problems with two cylinders. Chasing the reluctor wheel issue is a waste of time. Your engine is bad. You need to call whoever you sourced the engine from and get a replacement before you put another dime into anything else.
