Chrysler Repair: Sebring Electrical Follow -Up, Code 11 and P 1390, crankshaft sensor, crank sensor


Question
I did as you suggested and the engine cooling temp sensor is dropping resistance as the car warms up 843 ohms was the read out at runnig temp of 212f. I disconnected the ect sensor and the fan turned on reconnect the sensor the fan goes off. I am still getting code 11 on the mil, also p1390 read out on the obd scan. Intermitting CMP or CKP or Misfire numerator at limit. I dont understand when both those sensor are brand new as the distributor is also brand new and the PCM along with the cap, rotor, plugs and wires. EGR is brand new also the air idle sensor is new. The BCM is acting up but that has always been a problem long before these problem existed. Now the original Crankshaft sensor has a stonger magnetic field then the new one. The car is jerking real bad as I approach 40mph. Could the gas be bad? I drain the gas tank twice and swapped out the fuel filter no change. Could the Tranny Computer be causing the jerking and misfire? PLEASE HELP!

Answer
Hi Angel,
The 1390 says the cam and crank signals don't match up, and since you also have the 11 it would make me suspect the crank signal is the villain. You have proven then that the temp sensor is not the problem so the mixture is not likely the reason for your miss.
Who installed the crank sensor? Did he have the tip against the flex plate with the paper spacer still in place so as to establish the proper spacing?
My 2.5L manual says that the possible reasons for a P code like that are: open or shorted 8 volt supply (orange/white wires to the sensors); open sensor ground wire (black/light blue wire from sensor to pin 43 of the PCM; open or shorted signal circuit (cam:tan/yellow to pin 33; crank: gray/black to pin 32 of the PCM); excessive clearance between sensor and pulse ring or sensor and magnet, crank and cam respectively; damaged magnet or damaged pulse ring; failed sensor; failed pcm, or bad sensor connectors.
I don't have any other suggestions except these. Maybe you got a bad new sensor if none of the other itemslisted above divulge a reason upon investigation.
The only other reason for loosing power at higher speeds is that the catalytic converter is clogged. That can be tested at an exhaust shop. I don't think there is anything wrong with the gas, and I don't see how the tranny could be the problem. I would focus on the crank sensor.
