Hi there,

If you didn't use the factory sensor from the dealer then it's likely the problem. Take it out of the housing and check for burn marks on the sensor itself. Typically the average life of the aftermarket sensors is about 2 weeks. Also, check continuity to ground with a meter. If there is a bad ground it may be causing the issue.
