This is a great genuine Ford part. Fits perfectly. To make sure I fixed the exhaust emissions issue, I cleared the codes. It took about 3 or 4 day start-run cycles. The gas cap code is the last to be cleared after a faulty voltage on the purge solenoid. I tested the coil resistance of this part against the original which I think stuck. It was a little lower, so a little more current was required for each pulse. That's exactly what you want in this situation with the given code.
