what does it cost to replace the crank sensor and B1S1 air fuel ratio sensor in a 2006 Nissan Altima?
my niece is selling her 2006 Nissan Altima 2.5s sedan. Her check engine light came on at 100,000 miles. She took it in and had it reset, but the light kept coming on so they told her to try using premium grade gas. IF that didn't work the crank sesnor and B1S1 air fuel ratio sensor may need to be replaced. I am thinking of buying the car for my grandaughter, how expensive would these items be?
