I recently had the timing redone on my Ford 150 5.4L 3v Triton Engine. After work was completed I am now getting the following error codes at start up P0340 P0344 P0345 PO349. I also notice that the truck isn't getting as much power as before when I try to reverse up a driveway with an incline. The truck does not move after I press gas pedal to floor and nothing happens. I also cant get the truck to get enough power to get over the curve when reversing in my driveway. It wasn't doing this prior to changing the timing. I have also added a link for behavior of trucks prior to doing the timing. The previous issue does not occur anymore but I am now getting the power loss and the following error codes P0340 P0344 P0345 PO349

Question: The guy that did the work is stating that the error codes are not related to the timing being off. Is this a correct statement. He stated that the errors are due to another issue with the signal not getting sent properly. He also stated if he goes back in to check the timing to verify its done correctly he will charge me for another timing job.

Does anyone have any suggestions or recommendations for this issue?

Note: I googled a few videos and this video best best describe what was going on with my truck prior to changing the timing

 

The mechanic ****ed something up in the timing job, you could unplug the cam sensors and see how the truck reacts.
What reason did you have for having the timing redone?
By redone do you mean timing parts replaced or just taken apart and reassembled?

 

Originally we used after market Cam Phasers. I watched a few videos and they stated the error codes are from the after market parts. I purchased the Ford Phasers and replaced them with the new one from ford. The Mechanic took photos and verified that the timing from the previous job was done correctly. Once the truck was put back together and started we got the same Codes. We discounted the alternator and the error codes went away. We are at a lost at this point. WE also changed the cam phaser señors. still waiting to here back from mechanic and see if that correct any of the issue.

 

I will get the mechanic to unplug the señor and see what happen and respond.

 

Latest update The truck is back together and running good but we are still getting the same error codes. The truck is getting good power in drive and reverse.We just have the following error codes P0340 P0344 P0345 PO349. Can anyone please help or make a recommendation. Also changed the Cam phaser sensor but use after market parts didn't purchase from ford.

Let's hope the person that did the job has some good conscience and pride in his work.

How do you feel about splitting the bill for starters ? You are both in a tough spot right now.
Now, I get very uncomfortable using some aftermarket parts . Is there some way you both can agree to stick with OEM parts?
Even the experienced techs stub their toes , but we learn from those mistakes. In this case, it has to be fixed one way or another so very detailed checking will be required.
The one thing that needs to be checked and verified is the alignment of the timing spokes on the cam phaser on bank 2. If one is even slightly bent or out out of alignment it can cause codes to keep coming up and drive us up the wall. It is a tough sell to have the gent to want to open it up again, but I'll bet he is curious too. It's a long shot, but we're picking straws now so everything needs to be rechecked. There are some good videos on U Tube that you might invest a little time watching.

Another thing to consider, clear the codes , unplug the alternator and start the engine and see if some of the codes go away. If any of the codes go away , get that alternator off there, strongly recommend a Ford reman alt.

 

we checked the Timing spokes on cam phaser and they are not bent. Discounted alternator but was unsure how to check anything. All four Error codes come back after Two Key turns.

 

Not sure what "Discounted alt" means, please explain, thanks.

 

What do you mean by codes came back after two key turns?
Did you clear the codes, start the engine and they came back?
Did you do a on demand test and they came back?

Why did you originally get a timing job done? Was there any issues beforehand?
What parts were replaced during the original timing job and what all was replaced afterwards?
What new parts are OEM and what is aftermarket?
