Hello,
Over the winter my fuel gelled and backed up the fuel, truck died in parking lot. Replaced fuel filters and put in additive. Everything was fine. Drove 200 miles. Started truck up to drive to work the next day and got a check engine light. P008A "unknown DTC" and P0093 "Fuel system leak detected - large leak." You guys told me on here that that is usually a sign of loose filters. I cleared those codes and luckily they have not come back but I just got a P0341 "camshaft position sensor A Circuit Range/Performance Bank1" which I cleared and then it came back again. I just dropped it off at my dealer and they said they cannot access my ECU since it's tuned. They said that the P0341 code usually means a bad wiring harness and I should start saving my pennies. Any tips?
I should also mention that it had an abnormally long attempt to start immediately before the P0341 code. It normally starts on the 2nd to 3rd crank. This took about 10.
Find a different dealer, this one is trying to screw you over. Either they are crooks, inept, or hate tuned modified vehicles. Possibly all three. The fact of the matter is they are a repair shop and it shouldn't matter what you bring in, if they want your business they should try to do right by your vehicle. That would include diagnosing via the scientific method and positively identifying a bad part. If you tuned your truck, you own the truck. If you voided your warranty then you get to pay for it instead of Ford. Would they sell Ford a new harness and not put a sensor in, then say it needs a sensor too after their repair didn't fix the priblem? Would Ford continue paying them for poor diagnosis of expensive repairs?
Not saying you don't have a wiring issue, but prove it that's all. A sensor swap would be in order, at least chase the wires down with a meter. WTF? "IDS won't tell me what's wrong with it in 2 seconds, and you can't seriously expect ME to think for myself and at least TRY to diagnose somethig?" If every job was easy money and every customer had bottomless pockets we would all be rich.
Sensors usually have some sort of OHM reading you can test, in addition be certain it is getting power. Does it still have a long crank before starting? Those filter housings can have problems also. My dealer just ordered some $10 part for mine to deal with a long crank issue. I'm guessing the drain valve, but only because I can't think of any other part on it that would be that cheap and replaceable as a separate item. I should know when I get the bill tomorrow. I'd bet the filter change and long crank is connected. Mine started after the "water in fuel" light came on and I drained it through the petcock a few times, then just dropped the filter housing altogether. I doubt it is the upper filter, but the one under the truck seems to have all sorts of issues. If it isn't 100% tightened the truck wont even prime to start. If I recall it "clicks" into final position and has to be "clocked" a certain position. The tiniest bit of loose and it doesn't seal correctly. Check the O ring(s) on it?. Use the correct socket on it first and check it is all the way tight? Don't jam it tight, but give it a steady pressure pull on ratchet and see if it moves farther. First time I ever changed fuel filter on that truck I was almost 1/2 a turn not tight and it took an hour to figure it out. You have to use a wrench, not by hand.
I'm having the same problems over here on my 2013 6.7. p0341 and p0340. changed out the sensor and the truck ran a lot better but occasionally p0341 would come back up. the biggest problem I'm having now is the truck has to turn over way too long to start. once the truck is running there is no difference in power or anything out of the ordinary. starting to think I have a wiring issue. anyone have the schematics of all the wiring harnesses? any help would be much appreciated.
LOL....it might still help someone. I just joined this forum and, that post showed up somehow, I wasn't scrolling through posts or anything... I read it and was currently dealing with a similar issue, so I replied. He mentioned his truck was stuck in a parking lot, I assumed plowing, and fuel gelled, so it fit the current timeline with weather we have had. I didn't really look at the date.
Yeh, a forum update list posts the AI thinks is relevant to the topic you are looking at without respect to post date.
