Well the code does not mean that the sensor itself is the problem! Possible circuit to the sensor or engine noise the sensor is, well , sensing! However it could be a bad sensor but needs to be checked out first. Everyone assumes that a code points directly at the problem/sensor,, not the case at all.! Now that is when the true diagnostics begin by a qualified mechanic!!
