I just had this code pop up tonight.

That will put a damper on my weekend datalogging/retune shenanigans.
Any symptoms beside the code,rough idle,hesitation. Z
Nope, running fine and no parameters showing anything amiss.

It sure is upsetting to say the least,sounds like a variable cam timing issue in bank 2,cylinder 1, was curious what grade oil you were using on your experiment,just a thought and best of luck. Z

Eventually, the dealer diagnosed that my #2& #5 injectors had gone bad and they were replaced under warranty. I am assuming that they are the middle cylinder injector for each of the banks.

I was kind of surprised giving the low mileage ( < 18000 miles ) I have on my car.

So it wasn't the loose pin in the harness?
Did the light/code come back at a later date?

What is up with these fuel injectors failing on these ecoboost Ford cars? Where the heck did the Ford source these injectors, I have never heard off any manufacturer having a such bad failing rate on the FIs... They oughtta recall all these and put a reputable brand on there that will last.

I guess Ford is learning their way into DI, and they are locked into a production cycle with their supplier. What I WOULD like to see is more ready diagnostics of the FIs when the vehicle goes in for service, and replacement stock at the ready. Gas tanks with the Edge and Fuel injectors with the SHOs

Don't know if the Flex/XSport etc. also have similar issues.

FoMoCoSHO · October 31, 2015, 11:29:32 AM

These are Bosch injectors and they pretty much pioneered DI.

They are in focus's, F150's, SHO's, Sports, etc, and that's just one manufacturer.

I'm not sure the sampling size here is indicative of a defect.

SHOdded · October 31, 2015, 11:34:04 AM

Maybe they should lower the defect recognition threshold on the injectors used in boosted DI vehicles?

I hate to revive an old thread, but I've been battling a P0020 code for the last couple of months. It's an on again-off again issue. I may drive with it on for 50 miles and then with it off for 300 miles. I initially read this thread when it first occurred and thought my issue could also be a loose pin, but the connector on the VCT solenoid side appears to be fine. There are only two wires and neither of them are loose. Today, I finally became frustrated enough to give it another look. I read the code with my X4 and now it's throwing a P0020 and a P0022. The car idles perfectly and doesn't experience any drivability issues, but I'd like to resolve this.

Does anyone have a wiring diagram of the bank 2 circuit? I hope this doesn't come to actually replacing the solenoid. At a glance, it looks like that will require removal of the valve cover.

It looks like the OP's problem ended up being a couple FI's. Not sure why it throws that code but its something to look at.

Thanks Scott. I accidentally posted in the wrong P0020 thread. That's what I get for reading on my phone. There is another thread floating around here that details a wire chaffing issue that occurs near the battery box/radiator hose and the result is a P0020 code. While I haven't ruled out any causes at this point, the chaffed wire does make sense since I replaced my battery in late Summer. I think I just need to start removing parts to see what I can find. This is a bummer...

ZSHO · December 29, 2015, 09:01:10 PM

Joeleat think the sensor is located near the upper radiator hose,here's the thread,hope this helps any. Z http://www.ecoboostperformanceforum.com/index.php/topic,5280.0.html

Mine ended up being the pigtail.

If you have Torque, fire up vct commanded, actual, vct error.

When it happens you will see actual stop responding and vct error will match commanded.

They made a change from cable loom to a piece of tape on top of the pigtail for strain relief. Whoever assembled it didn't understand what strain relief meant so instead of a loop, they pulled it excessively tight through the tape and ruined the pigtail.

ZSHO · December 29, 2015, 10:09:19 PM

FoMoCoSHO is correct,new pigtail/terminal. Z

Joleat · December 29, 2015, 10:19:13 PM

Thanks guys! I appreciate the insight. We're expecting a lot of rain tomorrow, but I should be able to dig into it later this week. I'll report back with what I find.
