I decided to get it into a shop and have it checked. Otherwise you will need factory that will teach you and guide you through the diagnostic phase. This ability to alter valve timing is great for both power and fuel economy. The rest of the codes describe misfiring condition on several cylinders, but are really secondary symptoms of the timing issue. I am a 63 year old female and afraid to drive this vehicle. Registration is fast, simple, and absolutely free so please,! That made me start with the phaser.
They tightened the plug and sent me on my way. Sorry if I ramble on. Dec 19, 2017 I would veture a guess the failure is an emission code problem and the conditions for the failed problem are not met. A fellow grad who still lived in the area had a diagnostic and checked the codes. I recently drove my 2008 Ford Expedition 5.
Ford Expedition P0012 Symptoms When the timing is over retarded, it can really cause some issues with the motor. I know you're not supposed to do that and didn't want to screw up my engine anymore than it might already be. The idle will change and get worst if the intake is leaking. After a couple of drives the light came back. After checking into my room, I restarted - still rough idle and check engine light came on. What are the symptoms of the P0012 code? When you consider what these codes are saying, it becomes obvious that these codes are more indicative of a mechanical failure or the results of poor maintenance.
I had made one stop on the road with no idling problems. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. Code p 0171 is an O2 sensor, Code 0300 is random misfiring, Codes p0305 and 0307 are the 5 and 7 cylinder misfires. Unfortunately, if the is already on, it is doubtful that simply flushing the oil will solve the problem. The symptoms are of very little use in the diagnosis except for confirmation. This is because the cam profile will not allow it run a performance power curve when you need more power.
I took it for a drive and it definately had more power. With P0012, the camshaft actuator is leaving the timing retarded. Hi - all of these codes relate to timing chain, guides, tensioner, etc. Bastards hadn't tightened my plug enough and it slowly leaked out. The test fails when the camshaft timing exceeds a maximum calibrated value or remains in a retarded position.
When I pulled into my motel parking lot, it would barely idle. Well, work got in the way and I just got a chance to get it into the shop today. The cheater works by pressing down on the internal chain tensioner to make slack in the timing chain. I guess now its just seeing what the better option its cost wise. I love doing my own work and been using a Haynes.
It also requires that the timing belt be properly installed. A normal repair without the cheater involves removing the front of the motor up to the heads and still requires removing the valve covers. P0012 is generic, which means that it has the same definition for the Expedition as it does on any other vehicle. How serious is the P0012 code? This is still less than what told me was acceptable in there eyes. Two days later a rollback towed it to a local mechanic who merely reset the computer did not just clear the code, if I understood correctly and it idled perfectly. Or would it be easier to just replace it.
Thanks for the quick reply. However for the system to function properly requires that oil and filter changes have been performed properly and at the correct frequency. Possible Explorer P0012 Causes There are quite a few different things that can cause the P0012. The tech its telling me that the oil galleys are so clogged I'm looking at a rebuild or a replacement. I am pretty mechanically inclined I am a aircraft mechanic so I thought I could fix it myself and have a nice Expo for cheap. I know that restarting my laptop can solve many a problem, but can it be that simple with a vehicle that wouldn't run well enough to drive to the repair shop? The wiring harness to the intake camshaft position sensor may also develop a poor connection.
