Question about 2000 Jeep Grand Cherokee
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

Hello! Code P0340 can also be caused by a defective Crankshaft Position Sensor...
Pin # 1=Sensor signal...Grey/Yellow
Pin # 2=Ground...Brown/Yellow
Pin # 3=+5 volts...Orange
Check for +5 volts between pins # 3 and # 2...
Check the voltage present on pin # 1 to ground...
Use a digital voltmeter if possible...
