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 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.

    CODES,P0442,P0455,P0456,P1684


    P0442, P0455 AND P0456 are all evaporative leak monitor test failures (small, medium and large leaks). These codes appear anytime the integrity of the air space above the fuel or the lines to/from the vapor canister or purge valve. If there is no damage to the canister, check the lines that run under the van from the fuel tank and canister to the purge valve (under the hood). Also, check to make sure that the hoses are not split or disconnected where they connect to the purge valve. The P1684 is abit more confusing. This is not a valid DTC for your vehicle. It's possible the scanner the shop you went to is an OTC scanner that is reporting a false code. It's also possible they wrote it down incorrectly. The closest thing that makes any sense is a P1486 which would indicate a pinched hose in the same monitor system as the other 3 codes. Best of luck!
