Hello, 2004 ford F 150 5.4v super crew..
Mechanics have changed the Trotle Body, ran good for about 7 days then replaced some PCV Valve did do nothing... ( changed the oil they thought it had something to do with the oil ) nothing.. idles ruff shakes idle is about 55oo rpm.... they also said they checked for vacum leaks none....
p0012 code refers to some kinda camshaft senosr..?
some one told me to try seafoam some kinda cleaner put it down thortle body, engine.. gas.. have u ever heard of seafoam cleaner ?
This is not a problem with the camshaft position sensor. This engine has variable valve timing which is controlled by the powetrain control module. The most common cause for this problem is the Variable Camshaft Timing (VCT) valve solenoid. This solenoids job is to open and close to allow for the engine oil to retard the camshaft as needed. If this solenoid sticks open, you will find that this trouble code is generated as the camshaft on bank one is over retarded. Here is a definition of this trouble code so that you can better understand its meaning. There is also a list of things that could possibly cause for this problem.
you know by lookin now at the invoice it was VCT solenoid ( i put down PCV ) they replaced...... what else could it be.... ?
could this poo12 code be associated with ruff idle... or its 2 different things...
any other thoughts ? besides what the service manual states...
hello, should i just go to sleep.... maybe your in east coast might be late..
should we continue discussion tomorow ?
Camshaft positioning actuator.. where is it located...? can it be easily replaced ?
