I have a 2001 PT Cruiser
.I replaced the motor with a salvage motor and transmission
combination.The PT Cruiser will not start.It had a code P0601,and I replaced the ECM with a refurbished matching # unit.The car has 150 PSI compression,on all 4 cylinders,55lbs fuel pressure,timing marks in line,plugs creating spark.It TRIES to start.What I don't have is a 5-Volt reference to ground from the orange wire directly from the computer.I have cut the splice open that ties the sensors together and am dealing only with a foot long piece of wire off the computer.If I meter the orange wire to ground,I have 4.37V with an empty cam sensor plug.If I install the sensor,and it is the only sensor on that feed,I have .02V.Where the problem comes in,is I rotate the cam on the sensor and in theory it should climb to the full 4.37V in full throttle position.It does not! It only goes to .26.I cannot believe I have 4 exactly bad cam sensors,and 2 ECM,including one that is new that gives me the same reading.It's my understanding I must have this 5V reference to and through the sensors for the car to run.Any ideas?? TY
JA: Which particular sensor are you asking about? And have any trouble codes been triggered?
Customer: cam sensor does not increase to the input voltage..Only goes to .26V
JA: Are you fixing your PT Cruiser yourself? What have you tried so far?
JA: Anything else you want the mechanic to know before I connect you?
Customer: i have tried 4 cam sensors,a new computer,a matched computer with key and key sensor,and nothing works
