Fuel Level Sensor "B" Circuit Short to Battery |
|
DTC |
P206514 |
Fuel Level Sensor "B" Circuit Short to Ground or Open |
DESCRIPTION
The No. 2 fuel sender gauge is located inside the fuel tank and measures the amount of fuel. The No. 2 fuel sender gauge converts the fuel level in the fuel tank into a voltage value and outputs it to the combination meter assembly. The ECM determines when it is necessary to refuel the vehicle based on changes in the output value of the No. 2 fuel sender gauge.

P206514 |
Fuel Level Sensor "B" Circuit Short to Ground or Open |
No. 2 fuel sender gauge output voltage is less than 0.25 V for 30 seconds or more (2 trip detection logic). |
|

DTC stored |
|
MONITOR DESCRIPTION
The combination meter assembly sends No. 2 fuel level sensor signals to the ECM via CAN communication. When the ignition switch is ON, if the output voltage of the No. 2 fuel level sensor is less than 0.25 V or higher than 4.73 V for 30 seconds or more, the ECM will illuminate the MIL and store this DTC.

CONFIRMATION DRIVING PATTERN
HINT:
-
After repair has been completed, clear the DTC and then check that the vehicle has returned to normal by performing the following All Readiness check procedure.

-
When clearing the permanent DTCs, refer to the "CLEAR PERMANENT DTC" procedure.
Click here
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the ignition switch off and wait for at least 30 seconds.
- Turn the ignition switch to ON [A].
- Turn the Techstream on.
- Wait 30 seconds or more [B].
- Enter the following menus: Powertrain / Engine / Trouble Codes [C].
-
Read the pending DTCs.
HINT:
- If a pending DTC is output, the system is malfunctioning.
- If a pending DTC is not output, perform the following procedure.
- Enter the following menus: Powertrain / Engine / Utility / All Readiness.
- Input the DTC: P206512 or P206514.
-
Check the DTC judgment result.
Techstream Display
Description
NORMAL
ABNORMAL
- DTC judgment completed
- System abnormal
INCOMPLETE
- DTC judgment not completed
- Perform driving pattern after confirming DTC enabling conditions
HINT:
- If the judgment result shows NORMAL, the system is normal.
- If the judgment result shows ABNORMAL, the system has a malfunction.
-
[A] to [C]: Normal judgment procedure.
The normal judgment procedure is used to complete DTC judgment and also used when clearing permanent DTCs.
- When clearing the permanent DTCs, do not disconnect the cable from the battery terminal or attempt to clear the DTCs during this procedure, as doing so will clear the universal trip and normal judgment histories.
WIRING DIAGRAM
CAUTION / NOTICE / HINT
HINT:
Read freeze frame data using the Techstream. The ECM records vehicle and driving condition information as freeze frame data the moment a DTC is stored. When troubleshooting, freeze frame data can help determine if the vehicle was moving or stationary, if the engine was warmed up or not, if the air fuel ratio was lean or rich, and other data from the time the malfunction occurred.
