P0345 Hard start VDC light issues
Hey everyone, first post, but have read and studies a lot of posts. Great site!
Here is my situation - purchased this 2006 model here in Europe (yes Euro model) in February with 130K miles. Have replaced the standard high pressure power steering hose because of a leak. After about a month (?) after getting it, we started getting a P0420 code. It was winter and someone mentioned that the winter fuel additives that are put in in some places may cause that issue. Kept an eye on it and sure enough it went away in the summer time, only to come back in late summer. I think i need to replace the cat system. Now the P0420 has gone away but I have a new issue.
On a whim I filled up with 100 oct fuel and maybe coincidently, maybe not, in a very short time (day or so) started getting this P0345 (4 faults but all are P0345 related) with the slip and VDC lights also. I replaced both camshaft position sensors and still have the problem. A short time after changing those sensors, it started taking a long time to start once the key is turned on. It always starts, but it takes a while. I did a battery test and it goes down to about 9.9 V while cranking and while idling the voltage read on the battery is about 12.95 V. I know these are on the low side and may point to a weak battery.
Would this have anything to do with the fault codes?
I saw that one post talked about replacing the crankshaft position sensor and I purchased one, but for the life of me, i can't seem to locate it. It is not where my Haynes manual says it is supposed to be. Any guidance about finding that? And is it possible that it may also contribute to the problem?
For the sake of full disclosure, I did apply some brake squeal paste to the back of the pads at approximately the same time. Not sure if this would or could affect anything or not. I definitely did not get any on the pads themselves.
As if this is not enough, I also have a leak from the driver side (same as USA driver side) front wheel well area where the wheel well is louvered just in front of the wheel. There is a hose that was replaced in that area on, I think, the transmission cooler. I can't find any information on what exactly the function of that part is. I do all the work myself, with help from youtube and manuals when they are helpful. On a budget and would prefer to not take it to dealer as this model, and Nissans in general are not that common where we are in Europe (Slovenia).
Any help would be greatly appreciated.
