Hi,
I have a 2007 honda accord 4 door 4 cylinder.. I recently had my starter motor replaced, and for this car that requires you to take the intake manifold of the front of the engine to gain access. Trust me that’s the only way to get it. My mechanic did this repair as I did not want to mess around with sensitive throttle body and I just dont have that kind of experience. After the repair the car was fine, the next day after I picked it up, I noticed that one the bolts on the air filter box was broken, so I replaced it. ( this was not my mechanic who broke it , it was an oil change place i took it too 2 days before the starter went).
I realized that air was being drawn in from above the filter because of the broken bolt, so I decided to clean the mass air flow sensor in case it got dirty. looking back now I should have just left it, but i cleaned it about a year ago and no issues so I didn’t see any harm in doing so. I took it out, only 2 screws holding it in, sprayed it with mass flow sensor cleaner, about 15 very short sprays from a distance, then let it dry for 30 minutes, put everything back together and when I started the engine, the engine check light was on, and the idle is high, about 1500 when the engine is at operation temp in park. the code reads:
P0507- idle control system RPM hight than expected.also had another code, but that one doesnt show up anymore: P0102 mass or volume air flow circuit low imput.
If anyone know what i can do or what could be the problem please let me know. Also I herd that when the intake system is apart you have to do an idle relean procedure. I have done it 3 times now, each time the engine like stays on and idle remains high.
thanks.
