97 camshaft position sensor

[burtonsbs5114]

I have a 97 maxima, and it will have randomly have trouble starting. Some times it starts up right away, other times it takes a while to start. The battery and starter seem fine, it just doesnt fire. The check engine light came on and it said to replace the knock sensor and the cam shaft position sensor. Me being a newbe, i didnt realize there was 2 camshaft position sensors. Which one is bank 1??

There is only one Cam Shat Position sensor on your 1997 Maxima, but I suggest to have the battery tested, since the Cam Shaft Position Sensor code can be triggered by a low battery charge or bad starter. Don't just replaced the sensor because there is a code.

BTW the bank 1 is on the right side of the engine next to the firewall.

Oh, awesome thanks! I did a lot of searching but i could only find the 3.5l and that has two, so i figured the 3.0 had 2 as well. I will def check out the battery and starter out. It seems to hold a charge well though as it always cranks strong sometimes even after like 10 min of trying. I also noticed today that the check engine light turned off. This happened once before too. The check engine light will turn off for a few days and then turn back on. I will also have that starter check, what should i be looking for with the starter?

Ok, so i replaced both sensors as i had already bought them. I got them on ebay for about $25 each. I installed them and the car does seem to idle and start better. I had the battery checked out when i got my oil changed, and the guy said the battery is fine. I have not had the check engine light come on or n e starting problems since the starters have been replaced. Lets hope this fixes it!

Another issue:

I have this strange rubbing/ kinda grinding sound comming from the back of my car. It only happens when i am on the gas, and it typically only happens under 2k rpm. I am thinking the heat shield for the mufffler is loose and ratteling around. I tried to take it off, but it wont easily come off. I know i prob dont have the best description, but what are you views on the noise i am having?
