It wouldn't suprise me if it was bad. I always use OEM for all sensors. Even if the aftermarket sensor is made by the OEM supplier, the EOM quality control is different. A lot of times, the aftermarket part is an OEM quality control "FAILED" unit.
Also, check the wiring and connector. Make sure the wiring isn't rubbing some place. A short in the wiring can also cause the same issue.
