Some 2007-2009 Edge, MKX, MKZ, 2008-2009 Taurus, Taurus X, Sable, and 2009 Flex and MKS vehicles equipped with a 3.5L or 3.7L engine, may exhibit a malfunction indicator lamp (MIL) on and one or more diagnostic trouble codes (DTCs) P0011, P0012, P0021, P0022. Vehicle may also exhibit rough idle or misses.
Follow the service procedure steps to correct this condition.
The Oil level is OK it was built 10/2008 and it is the 3.5L. The Error P0018 is for Bank 2 Sensor A. I think. I do not understand if I should replace the left, or right kit, or the Solenoid? please help. Also my scan tool will not read (pids), or I don't think it does ??
After I cleared the codes, a P0021 popped right back into pending codes and the engine is idling a little rough. The Kits and the solenoid are not in any dealership here. I ordered them, kit =$245.45 solenoid = $98.32. In looking at the solenoid, it looks like it is pressed into the valve cover, and it looks like it can not be replaced. So I guess the kit contains a left or right valve cover with a way to replace the solenoid. Is this about right or am I completly wrong?
Also I forgot to ask you, since it will be a couple of days before the solenoid arrives, will it hurt the engine if it is driven?
