When your vehicle presents Dodge P2068 Code, it indicates a trouble code associated with the Fuel Level Sensor 2 Circuit High. This code is a bussed message from the Body Control Module (BCM) to the Powertrain Control Module (PCM) and is designed to maintain the fuel level rationality. If the vehicle has a saddle tank fuel system, diagnostics for both the sending units and the siphon tube must be done to keep the OBD monitors from being disabled. The leading causes of the Dodge P2068 Code can be narrowed down to issues with the Fuel Level Sensor 2 Signal Circuit, the Fuel Level Sensor 2 Signal Circuit being shorted to voltage, or the Fuel Level Sense Return Circuit being open/high resistance. To ensure accurate diagnosis, checking for related service bulletins is essential. In this article, you will find a table featuring the causes and solutions related to Dodge P2068 Code.

Fuel Level Sensor 2 Signal Circuit Shorted to Voltage
If the vehicle presents a Dodge P2068 Code due to a fuel level sensor 2 signal circuit being shorted to voltage, the cause should be further diagnosed. This can be done by checking the wiring harness for any signs of corrosion or damage. If the wiring harness is fine, the fuel level sensor should be replaced.
Fuel Level Sense Return Circuit Open/High Resistance
If the vehicle has a Dodge P2068 Code due to a fuel level sense return circuit open/high resistance, inspecting and repairing the circuit is the best solution. This can be done by checking the wiring harness for any signs of corrosion or damage. If the wiring harness is fine, the fuel level sensor should be replaced.
Fuel Level Sensor 2
If your Dodge P2068 Code is due to a faulty fuel level sensor 2, the best solution is to replace the fuel level sensor. This can be done by checking the wiring harness for any signs of corrosion or damage. The fuel level sensor should be returned if the wiring harness is OK.
Body Control Module (BCM)
If the Dodge P2068 Code is caused by a faulty Body Control Module (BCM), the best solution is to replace or reprogram the BCM. This can be done by checking the wiring harness for any signs of corrosion or damage. If the wiring harness is OK, the BCM should be replaced or reprogrammed.
