SOURCE: CHRYSLER CONCORDE WITH DIAGNOSTIC CODES P1768 AND P1792

P1768 MEAN TRANSMISSION RELAY ALWAYS OFF..WAS UNABLE TO FIND P1792..IF PROBLEM STARTED AFTER HEADS WERE DONE..LOOK CLOSELY AT AT ENGINE MAIN WIRING CONNECTORS AND GROUND CONNECTIONS THAT ARE ON ENGINE..LOOK FOR GROUND EYELETS NOT SECURED OR LOOSE..LOOK FOR ANY PINCHED WIRING AS WELL..MAKE SURE NO SPREAD TERMINALS IN CONNECTORS AS WELL..YOU CAN ALSO TRY SWAPPING ANOTHER RELAY IN PLACE OF TRANS CONTROL RELAY..MAKE SURE PART NUMBERS MATCH UP..
TCM(NGC)PIN 16 IS TRS T3 SENSE CIRCUIT..PIN 17 IS NOT USED...HAS TO DO WITH TRANS RANGE SENSOR..I DON'T THINK THIS CAUSING YOUR PROBLEM..

The 1684 is about the battery supply to the transmission contol module having been lost sometime in the recent past. It could be an actual disconnect of the battery occured, or through some testing that happened, or a loose wire but in any case I doubt it would affect the engine running.
On the 1297, that one is very specifically pointing to the manifold absolute pressure sensor which is mounted directly to the intake manifold. It has several possible causes:
the 5V supply to the sensor may be open or grounded and that can be verified by reading the voltage on the violet/white wire with the ignition switch in the run position. The signal wire can be open or shorted to ground and that could be checked by measuring between the plug to the module (dark green/red wire) and pin 36 of the plug to the engine controller. The sensor could be loose in its mounting position.
But most likely the sensor itself is faulty and it is easy to replace (a couple of screws). It should cost less than $100 for the part itself.
I would therefor tell the mechanic to examine this MAP sensor and verify what is the status of this sensor and its circuit before doing anything else. I can't give you any opinion about the noises but if the MAP sensor signal is lost then the fuel/air mixture will be imperfect which will often cause not only rough idling but even refusal to start.
Don't authorize opening the engine until you are satisfied that the MAP code has been solved by erasing it and trying to restart the engine and having ir no longer appear. That is the first order of business.

302 is misfire on cylinder 2. Please see my tip at http://www.fixya.com/cars/r6715318-causes_gasoline_engine_misfires .
1684 is battery disconnected, which you caused when you disconnected it--you can ignore that. You probably have an intermittent misfire. Please follow my troubleshooting steps and let me know if you have questions.

SOURCE: Got codes P0401---EGR Valve. P1684---have

P1684 Metering Oil Pump Position Sensor Circuit Malfunction, , on a dodge it means just that , you've disconnected the battery its just a status code,, don't worry about this one,, Now the P0401 Exhaust Gas Recirculation Flow Insufficient Detected,

  • Use a vacuum pump and pull the EGR valve open while monitoring engine RPM's & DPFE voltage. There should be a noticable difference in RPM's with the EGR open
  • Clean out the EGR valve and/or tubing to remove deposits
  • Check the voltage at the DPFE, compare to specified values (refer to a repair manual for your specific model)
  • Replace the DPFE sensor (with a good quality / OEM one)

    I looked up the code and it means that the battery has been disconnected within the last 50 starts. Check your battery cables and/or battery at your nearest auto parts store. The battery can be checked by them while on the vehicle. Hope this helps.

    I got two odometor codes p1684 and p0700 do you know what it means 2002 chysler town and country


    P0 700 is a transmission control malfunction and P1684 is a indication that your battery was disconnected within the last fifty states.However what is puzzling is your PO 700 is a generic code your P1684 is a dedicated Chrysler code your cars computer should only store one or the other not both.

    What are troubleshooting codes P1684 and P0456?


    P0456 is a small vacuum leak - see if you can trace down the vac lines for inspection according to the diagram that's on the sticker under the hood (it should be near the end of the hood prop on the covering over the radiator). I just took a picture of my 2002 Chrysler Town & Country but to get it small enough to upload you can't read the detail.

    P1684 is an easily trigerred code that is from a diagnostic reader or battery issue - not 100% sure of it's cause but it does not trip the engine light.

    2004 grand caravan, P0456 and p1684 codes appeared at same time. P1684 dont seem possible (as discribed in code book), but lights (all) seem to surge or flicker at times. I disconnect batt. and codes...


    P1684 You might have a voltage drop for a second, then the system will pick that up and say that you took off the battery connector. The battery may be going out or the alternator. P0456 may come up if you put gas in the car with the car running. The gas cap my not be working or be put on right. Good luck. ps Check to see if all the wires that have to do with the charging system are tight. everything!
