I was driving and my car died and wont restart. long cranks but wont turn over. I changed the battery still no start.I checked faults codes and got p0340. I changed the cam sensor and code went away. I checked codes again and got p0522. changed oil and oil pressure sensor and car still wont start. I disconnected the battery 1 hr to reset pcm. still getting p0522 how can i get the engine to build pressure for the sensor if the car wont start.

Yes replace the battery temp sensor as per the error code p0516 showing up.The battery temperature sensor is located under the vehicle battery and is attached (snapped into) a mounting hole on battery tray. The sensor is located under the battery on drivers side of vehicle. The ABS battery tray will need the left and right edge lips ground off to allow the 10 inch long battery to sit in the tray. The tray should be retained so that the battery temperature sensor will continue to function. ---------- This will help.Thanks.Helpmech.

Since the timing belt powers the Oil pump, water pump, and cams, this would explain the lack of oil pressure, no spark, camshaft position sensor malfunction code, and possibly a crankshaft position sensor malfunction code. Have the timing belt checked and replaced. I believe the engine in your PT Cruiser is an Interference Engine.

An interference engine is a type of 4-stroke internal combustion engine in which the piston and valve paths may "interfere" with one another as a result of incorrect timing in their movements. The chances of no internal engine damage due to a timing belt failure are slim to none with an interference engine. If the timing belt is found to be the culprit, which I am 99% sure it is, have the head compression tested, and have the head, pistons, and valves checked for damage.

This indicates that a problem was detected in the camshaft position sensor circuit. Since it says circuit, that means the problem could lie in any part of the circuit - the sensor itself, the wiring, or the PCM. Don't just replace the CPS (camshaft position sensor) and think that will definitely fix it.

Symptoms can include:

• 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

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

Hope this helps; also keep in mind that your feedback is important and I`ll appreciate your time and consideration if you leave some testimonial comment about this answer.

Thank you for using FixYa, have a nice day.
