NEW CAM SENSOR P1391 CODE.

Question

JEEP 4.0 CAM SENSOR REPLACED PUT IN TIME. SAYS P01391 CAM SENSOR SYNCRO- NO CAM SIGNAL, BUT STARTS UP JUST SKIPS WHEN RUNNING. I'VE CHANGED CRANK, CAM, COIL,WIRES ,CAP ROTOR, ECU, MAP ( VOLTAGE TO HIGH)
FOR CODES P0301 TO P0306. ANY HELP WOULD BE APPRECIATED. THIS IS 1997 ZJ TSI 4.0. THANKS RICH

Answer 1

P1391 Intermittent loss of CAM or Crank position sensor
