I have a 2012 versa 1.6l Manuel with 102,000 miles. Have p0101 camshaft circuit malfunction code. Getting proper signal to sensor and I don't want to throw one on with all the forums iv read that it was useless. It still runs am currently 1800 miles from home. It idles normal with no sounds. When I go to take off in first when I get to 3000rpm there is a tick/flutter sound that gets louder but I back off when it sounds. Very poor acceleration especially up hill. I have changed plugs, oil and cleaned and check all sensor plugs and sensors. Lost on what to do now. Cheaper camshaft sensor I have found is 80 bucks. Any input is greatly appreciated. Thanks in advanced.
