Hi!
I am new here. Sorry for my english A few days ago I saw on my desk check engine(DTC P0344 and P0016). After this, there was a problem-engine was going good to some 3000RPM I think, more than 3000 was a tragedy. I change the camshaft sensor and nothing change. Because I had also problem with oil consumption, I decided to take engine to pieces. After that, I Saw that the timing gear looks ok, signs are on place. Flex plate is also ok. So, why I saw Check engine? Men in the shop told me that should be 14mm camshaft gear. My car is from 2005 and there was a 17mm gear. Now I dont know which one is correct. I also saw, that on my engine block is chrystler mark-is it ok or not I dont know. Please help me
You did an engine tear down for those codes - wow! Did you at least test the camshaft sensor signal with a scope before doing so? Sorry to sound so negative, but it doesn't sound like you're doing the proper type of diagnosis. (unless there's a bunch of stuff you left out)
Ok, I will try to assemble the engine and I will test two sygnals-on one channel will be camshaft sensor, on second channel will be a crankshaft sensor. I think that this is the only way to check it
I put everything on a place. Engine is like new, chain new the same problem P0344. On monday I will check two sensors on a skope- camshaft sensor and crankshaft sensor and we will see.
That seems to be a fairly good square wave coming from the sensor, but the audio in the video sounds like knocking to me. Did it sound the same way before the tear down of the engine? What codes are showing up now, and what is the oil change history on this van?
The sound before was the same. Now is P0340 and P0344. After clear there are the same codes. I dont know the history of this engine, a few k kilometers only. Engine was rebuild- honing, new pistong rings e.t.c.
The knocking sound can be from cam sensor possibly, because when I put this sensor to whole, there was a contact with cam gear on the begining and the sensor(I dont know how to say that-was wiping or was scraping, rubing)cam gear. I have a new video with two sensors together. Maybe this will help. I am not a specialist, but I think that problem is with reading by cam sensor-you can see it on a screenshot
