Question about 2002 Jeep Liberty
DTC P1391 is "Intermittent loss of Camshaft Position Sensor (CMP) or Crankshaft Position Sensor (CKP)".
So the problem is with the CMP or CKP or the wiring in the circuit.
The Camshaft Position Sensor is located in the distributor on all engines.
For this test, an analog (non-digital) voltmeter is needed. Do not remove the distributor connector from the distributor. Using small paper clips, insert them into the backside of the distributor wire harness connector to make contact with the terminals. Be sure that the connector is not damaged when inserting the paper clips. Attach voltmeter leads to these paper clips.
