P0020 DTC

Went for a drive yesterday and my 2014 SHO lit up the check engine light. Of course, I used the LMS tuner to read the code and it was P0020. Googled it, went back to stock tune and baby'ed my car back home.


Today, I took it to the dealer and they had to keep it over the weekend because they could not get it to it in time. The car has less than 7k miles on it.


Hopefully, I get good news on Monday.
 
Car is still @ dealer and they called me to say that the diagnostics are inconclusive.


So I researched it the code and according to the http://www.fordobdcode.com/p0020-ford web site

P0020 - "A" Camshaft Position Actuator Circuit (Bank 2)



OBD Trouble Code P0020 “A” Camshaft Position Actuator Circuit
What does the code mean? OBD-II Code P0020 definition:
A P0020 code definition:the VVT (variable valve timing) or VCT (variable camshaft timing) components and the car’s PCM (powertrain control module). That consists of an oil control valve (OCV), also called a solenoid valve and other components. Basically the check engine light and associated P0020 trouble code means that the voltage in the circuit has fallen below a set limit for a specific amount of time (varies by make/model/engine). Bank 2 is the side of the engine that doesn’t contain cylinder #1. Note: This DTC is nearly identical to P0010
Symptoms of OBD code P0020
Check Engine Light illuminated (Malfunction Indicator Lamp) Rough running other symptoms may also be present
Causes of the OBD-II code P0020
A code P0020 may mean that one or more of the following has happened: Faulty oil control valve (OCV) Open or short in the VVT/VCT circuit Open or short in the OCV / solenoid valve Damaged computer (PCM)
Solutions Some recommended troubleshooting and repair steps are: Carefully inspect the Bank 2 VVT/VCT system circuit wiring and connectors, repair as required with a warm engine, test the operation of the OCV, replace/repair as needed
Related Codes P0010 P0011 P0012 P0021 P0022
 
The actuators have been a problem in other for engines, my wife's escape they went bad in and is well know problem TSB for them also.

hopefully the dealer won't give you any trouble regarding the reflash back to stock tune.

It might end up a discussion point... but likely only if Ford corporate field engineers get involved.  routine OBDII screening can only tell when and how many time the port was accessed.... I have told my dealer that I routinely do so with my MX and that any autozone will do it... as well as many gauges and programs (like torque) on the market.    Even then I would also argue that the TSB is there proving Ford is aware of this as a possible known manufacturing defect present at assembly antedating any tune... e.g., that the tune is not the cause.
 
It took a week but I finally got my car back and the dealer did ask about whether I had a tuner... I said no! I had reflashed it to stock before turning it in.


They tested all the components and everything was fine. They reset the PCM and it is driving fine now[font=verdana, arial, helvetica, sans-serif].[/font]


I will wait another week before I put the LMS tunes back.


If someone knows what TSB # is associated with the actuators, I would be most grateful. Might need that info in case it comes back.



 
After a week at the dealership, I got the car back.
Drove it around for ~350 miles and everything was fine. 
Was ~50 miles from home when the check engine light came on. Pulled the DTC and it is the same as before P0020.
Drove it to the dealership late in the day and they said bring it back in the morning. Drove off the lot, and less than 3 miles later, the check engine light went off.
Drove around for ~100 miles, light was off.
This morning, I am driving to work and the light is back on.


So it is going back to the dealer... I am thinking that the solenoid has gone bad or is defective.


Updates will follow when I know more.
 
I got my "baby" back yesterday from the dealership.


The problem in a nutshell: a loose pin in the wiring loom!!!
 
Glad that's all it was!  Bit early for wiring problems, but hey ...  Did they say exactly where it was?

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.
