Question pt troubles

I bought a used 05 pt cruiser touring edition non turbo with 100k miles.
After a battery replacement things were going good (other than her gas guzzling)
A couple months later I'm driving to work at 4 in the morning, i get off the freeway and theCEL comes on and it starts hesitating. After visiting this site i learn my pt is in 'limp mode' i did the 'key dance' and pulled error code P0340. So i bought the part from the dealer and replaced it. Reset the codes. Car remained in limp mode. We replaced the spark plugs, spark plug wires, did a full tune up, car remains in limp mode. I have learned so much from this forum and i do love my pt, but what else can i do to pull her out of this?

Please help.

Default Re: pt troubles

Here's from OBD codes
Hard starting or no start
Rough running / misfiring
Loss of engine power


A code P0340 could mean one or more of the following has happened:

a wire or connector in the circuit could be grounded/shorted/broken
the camshaft position sensor may have failed
the PCM may have failed
there exists an open circuit
the crankshaft position sensor may have failed

Possible Solutions

With a P0340 OBD-II trouble code, diagnosis can be tricky at times. Here are some things to try:

Visually inspect all the wiring and connectors in the circuit
Check for continuity in the circuit wiring
Check the operation (voltage) of the camshaft position sensor
Replace the camshaft position sensor as required
Check the crankshaft position circuit as well
Replace circuit wiring and/or connectors as required
Diagnose/replace the PCM as required
