Code P2068 Chrysler Description

The P2068 Chrysler diagnostic trouble code (DTC) refers to the Fuel Level Sensor 'B' Circuit High. This code indicates that there is a problem with the fuel level sensor circuit in the vehicle. The fuel level sensor is responsible for measuring the level of fuel in the tank and sending that information to the engine control module (ECM). When the sensor detects that the fuel level is high, it triggers the P2068 code.

Discuss the causes and fixes for P2068 Chrysler OBDII Code

  • I have a chrysler 300 2006 3.5 v6 I have 2 codes after replacing primary fuel pump and sending unit new relays and fuses and crank shaft sensor codes are p0463 and p2068 have no clue

  • Any other symptoms? did you use new parts? The system is very simple and there is no other component that can affect the signal, other than the fuel sender unit and the cluster. My only guess is that the wires of the fuel sender unit were not properly connected during the fuel pump installation.

  • I checked the pigtail that connects to pump and it has power the fuel pump is still not coming on my fuel pump was going out went to store came back out it would crank but would not fire so went ahead and changed pump but same result crank but no fire

  • And yes I used new parts

  • If you notice both codes are for "Circuit High" that means that the problem is not the power but the ground to the sensors and fuel pump.

  • So would be the best course of action

  • Since you have the code of the fuel sensor unit and the fuel pump is not working, then the problem is either no bad fuel, power to the pump (and sender unit) or poor ground. Since you have already replaced the fuel pump and there is power to the fuel pump connector, then the next step is to check for ground to the connection

    Disconnect the fuel pump connector and check continuity between the BK/OR (Black-Orange) wire and body ground (any metal part of the vehicle body). Continuity should exist.

    Also, please make sure to double check if there is battery voltage at the DB/OR (Dark Blue-Orange) wire.

  • Had somebody hook it up too all data I need coil packs now I just need to find out how many

  • Disregaurd last statement I don't think anyone knows what they are doing here in indiana cut throat mechanics anyways a friend of mine is a mechanic and he said you all go through a trouble tree to find problem well I know for a fact I have spark my brother sprayed something into the throttle body and car started and ran on its own until it burned off what he sprayed into it so what's next

  • I agree with your friend, I didn't think the ignition coils will set the codes and cause the no start situation. Did you check the ground?

  • Waiting on voltage meter

  • Well from what I understand I put the pump in wrong not sure yet have one of my brothers that's a mechanic finally come over to see what the problem is let you know what is wrong and if I did it

  • Ok I have a question looking under car noticed a hose hanging found out it connects to th pcv valve will that keep car from running

  • Probably not, if it goes to the PCV valve then is just a breather. Usually connects to the air filter box.

  • So I have a 2005 Chrysler 300. Originally it needed a key made for it... I got a new key and had it flashed to my car . It won't run... I have power coming out of the ignition switch but no power going into the starter on the the remote wire side. I can hook a remote starter up to it the starter and it will turn over but it runs for about a second and shuts off. I put my code reader up to it and it came back with a 2068 code and it says fuel level sensor B circuit high. I have checked all fuses in both fuse boxes and they are all good. Please help

  • The P2068 code is for the Fuel Level Sensor, which could cause a no start problem, but the engine should crank. If the engine is not cranking, then the problem is not related to the Fuel Level Sensor.
    My guess is that the new key was not properly programmed to your vehicle.
