Smile P0340 cam sensor code in 2006 cruiser

Have a 2006 non-turbo that has been trouble-free for 38,000 miles. But now, every couple of weeks, very intermittent, it surges and bucks. Turn the engine off, restart and it is fine.
Yesterday had it checked: P0340 code; bad cam position sensor.
Can anyone advise: if the sensor was bad, wouldn't it be 'bad' all the time? Does this problem look more like a loose wire or a short in the connector, rather than a problem with the sensor itself? If I replace the sensor, shouldnt I replace the connecting wire also? Also, isn't 38,000 miles a bit short of expected life? SHouldn't this sensor last for 50-60 thousand miles?
Thanks for any help anyone can provide!

A few of us have had an issue similar. Follow the wire from the cam shaft position sensor back towards the firewall and be sure it is not damaged. Mine was not and I replaced the sensor and have had no problems since.

Welcome to the forum.

Sure parts should last forever, but they don't. I have 96,000 without changing the sensor and thousands of other do too. Owners have the intermittent sensor problem all the time. You can try wiggling the wires in case that might be the problem. If the light goes away, you have a short in the wiring.

I was having the same problem with my PT but getting no codes. I replaced the Cam sensor and that fixed it for a few weeks, then it came back. Then I replaced the crank sensor and the problem has been fixed for years! Hooray!

I finally got the damn connector off but since light was fading, decided to hook everything back up and try it...error code went away and it runs like before. I'm going to change the sensor anyway, just needed to get it home to work where all my tools are.

You will need a (DRB) scan tool to clear the battery fault code, it won't clear itself. Fault code P1193 indicates that the intake air temp sensor voltage is too high. This sets any time the voltage exceeds 4.9 volts. The PCM sends voltage from pin 52 via the black w/red stripe wire to the sensor. The black w/light blue wire is the ground. You should not measure more than 5.5v with the ignition on the connector unplugged.

Possible causes are:

Bad ground circuit (several other sensors share the same ground point, so this is unlikely)
Open circuit from the PCM to the IAT
Intermittent connection
Bad PCM
Bad IAT

The scan tool will also help you pinpoint the reason you have the non-start problem. As you said, someone else changed the Crankshaft sensor even though the code was for the Camshaft and now his PT is running fine.

1st thing to try...Disconnect the negative wire from the battery, then, remove the connector from the sensorm then reconnect...might be able to start it and it will last until you get to your mechanic. Unless, of course, you want to change it yourself.
Also, removing the battery connection for over 20 minutes will reset the codes. At least it did in my case.
