CivicSi907 Posted May 23, 2016 Report Share Posted May 23, 2016 Hi guys, I am from germany and own a 2007 Edge for about 1 year. The Check Engine Light, was alway lightning, but the car runs smooth and without any problems. Now I want to sell the car, but I think its very difficult to sell it with the CEL blinking up. Sometimes the light goes off and then it goes on again after 1-2 days or so. I bought a ODBII Diagnostic tool to delete the error, but it also comes back. It is showing me error P0020. What could this be? Could it be the camshaft sensor's? Where they located at? Or what's the problem, because the car runs so well! Thanks in advance!

enigma-2 Posted May 24, 2016 Report Share Posted May 24, 2016 (edited) A P0020 code refers to 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. 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) 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 Edited May 24, 2016 by enigma-2 2 1 Quote Link to comment Share on other sites More sharing options...
macbwt Posted May 24, 2016 Report Share Posted May 24, 2016 If you are having these issues the question is what is the condition of your oil and is it being changed on a regular basis. VVT do not like dirty oil or heavy viscosity oil. Also the plugs, when changed what miles are on them as this could be a precursor to the PCM failure. Are all cylinders firing or is there a regular miss on them or some? the plugs can miss up to a point before a misfire code is set also. 2 1 Quote Link to comment Share on other sites More sharing options...

CivicSi907 Posted December 6, 2020 Author Report Share Posted December 6, 2020 (edited) Sorry for bumping this old thread, but I am having the same CEL P0020 error on my 07 Edge for about 4 or 5 years now. The car runs smooth all the way. Finally I decided to work on the CEL so it won't come back on again. I already changed the camshaft positions sensors bank 1 and 2. What would you guys do next? Oil change with Motorcraft oil or other recommend oil? Change the Oxygen sensors? What else? Reset and Relearn the VVT? Thanks for any help.

What's the mileage? What oil change intervals, what oil used and what oil filter? This is quite common on poorly serviced vehicles where the sludge causes issues with the camshaft Oil Control Valve (OCV) but someone with a scanner can actually do the required diagnostics to confirm what's actually wrong before throwing more parts at it.

Need more than the error codes read - need to live scan the data - you say you had it at a mechanics shop? - best to find a qualified service shop.

WWWPerfA_ZN0W Posted December 7, 2020 Report Share Posted December 7, 2020 did you replace the cam sensors (under the intake) or the VCT solenoids (on top of the valve covers/belt side of engine)? want to be sure because ford uses interchangeable terminology on some things.

The mechanic shop owner is my cousin, thats because I went to him. I just ordered 7 qts of Motorcraft Premium Synthetic Blend; SAE 5W-20 and a Motorcraft Oil Filter.

WWWPerfA_ZN0W Posted December 8, 2020 Report Share Posted December 8, 2020 These are what I am referring to. You do have to remove the valve covers to do this work. At least bank 2 is right up front! 1 Quote Link to comment Share on other sites More sharing options...

My personal preference is always a diagnostic approach which in your previous response indicated to me that's not your preferred path, so I have no response to that last question.

Not sure what your expectations are here - you chose not to respond to that question when I asked it earlier. The reason behind that question was to ascertain if this could be a case of maintenance neglect, which results in sludge, and sludge doesn't work well with any engine and particularly the Variable Valve Timing controls.

akirby Posted December 9, 2020 Report Share Posted December 9, 2020 You're damn lucky the engine is still running. How do you go 5 years without changing the oil? Change oil and filter with fresh motorcraft 5W20 blend. Run it long enough to get it up to temp for 15 or 20 minutes. Change the oil again. Keep doing that until the oil stays clean. Then resume diagnostics. Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted December 9, 2020 Report Share Posted December 9, 2020 can't possibly be talking about ENGINE oil, can we, LOL! Some use "oil" instead of "fluid" - trans, power steering, sometimes even brake, LOL. OMG 5 years w/o engine oil change? No way. Quote Link to comment Share on other sites More sharing options...

I responded with the answer that I have ordered 7 qts of oil. It was meant to be the answer you wanted to have, that I didn't do an oil change for many years. Hope you understand what I mean.

I gathered that you were not proficient in English and have no issue with that. Quote What's the mileage? So, have you done 5,000 miles in the 5 years its not been serviced, or have you done 300,000 miles in 5 years without a service? Clearly the engine has suffered due to lack of maintenance, but how badly none of us can tell, so again, best find a qualified mechanic that can assess the engine and decide the next steps such as an oil flush and frequent oil and oil filter changes.
