OK, this is BS!! This is my updated story. Questions are in bold letters (feel free to answer)
I'm having the same problems.
The car was fine for about 2 weeks and then the same problems started reoccurring.
I would get P0016 P0340 and P0344. I noticed the car would take FOREVER to start when it was cold outside.
I'm guessing the PCM can't find what stroke the engine is in from the cam sensor, so it starts eventually in limp mode?
I thought limp mode limits the car to second gear(?), BUT it only limits only limits mine to 2500 rpm?
It changes gears fine it seems.
ANYWAY, I thought I should start looking at other things since I JUST replaced the cam sensor.
I first checked the voltage to both sensor, inspected the wiring harness and connectors for opens and grounds but everything looked good from the sensor connectors to the PCM. I pulled on them, shook them around, twisted them...
Continuity was good for everything.
I decided to change the timing belt (never replaced) and replace the crank sensor since they are associated.
When I inspected the old belt it looked fine, but it was way past due.
Both cam gears had their marks JUST to the right of the 2 housing marks instead of in between. Can that be normal over time?
No matter what I tried they would not go back to the same spots with the new belt. Crank it around,align,crank it around,align. I think I spent 2 hours just trying. They are now both in between the marks. This is all with the crankshaft pulley at the TDC mark.
I started the car with the front covers off and no accessories for a minute or so.
It started right up and ran with no abnormal noise.
I put it all back together and took it for a short drive. Everything seemed fine.
I do hear a whirring zzz-ing noise when accelerating though. Very subdued. Noise from the new timing belt maybe?I also hear a very high pitched whistling noise. It comes and goes. Very loud near the back of the intake. Never heard it before now, or I never paid attention?
Can't hear it when the hood is closed or inside the car...
Here are videos without accessories and after driving it around all afternoon(from my youtube channel):
First vid (watch in hi def)--without accessories,battery getting low, you can hear the whistle. Very loud near the back of the intake.NO CODES Crankshaft pulley wobble OK or too much?
Second vid (watch in hi def)--with accessories after driving for awhile.Fan kicks on.NO CODES Still hear whistle. Don't know if it is related to my problem. Just an anomaly?
So my wife takes it took work yesterday morning and a gets an engine light.
I'm off to run errands and stop by to take it from her. It reads P0340 and 344.
I clear the codes with my Actron 9190 and take it around all afternoon. 80 mph on the highway for 10 minutes, all around stop and go traffic,shifting into passing gear,84 degrees outside. Not a peep from it. I think I've got it licked. I bring it home and take the second video.
I let it sit until it's cooled off and add some makeup coolant. I go to put it in the garage a few hours later. IT WON"T START!!!
Crank it over and over and over and it finally starts giving me those same codes.
I'M AT A LOSS WITH THIS ONE.
Do I have a new BAD cam sensor? Is the PCM faulty?
I saw this thread on 300M.org :
ALL IDEAS ARE WELCOME INPUT!!!!!
Well at least the P0016 is gone.. I just jinxed myself
