Hmmmm...

Lately the black PT takes 1/5 - 2 seconds of cranking when I turn the ignition key before it starts. Used to fire up in less than half a second.
Wonder if it could be a tired sensor?

That could be caused by a multitude of problems. Fuel delivery, bad spark plugs, vacuum leak, loose or bad gas filler cap, to name just a few.
Check if the electrical plug is secure on the sensor.
See if you're getting the P 0340 code?
If so, that code points to the cam positioner sensor.
Replacing it with an original equipment Chrysler unit might help.
I've been told to use only the original equipment sensor as the aftermarket sensors, even though they're cheaper, don't always function as well.
Attached is a photo of the sensor showing where it's found on the engine.
I hope that helps you.

I would suggest checking the battery cable contacts. If good have a battery load test done.

Thanks! No codes, not a loose gas cap, no vacuum leaks.... I think I will replace the plugs (last replaced 50,000 miles and six years ago) and put in a new cam sensor. Yes, it will be OEM! I learned my lesson a few years ago when I replaced the engine mounts in my Camry with 'cheap' ones (made in China!) that only lasted two years and 30,000 miles.....

You might have a battery drain issue. Is it worse if the Pt Cruiser sits for a while?
