Fuel Level Sensor "A" Signal Stuck In Range |
The
change in the fuel sender gauge value is below the threshold when a
certain amount of fuel is calculated to have been consumed. (1 trip
detection logic). |
- Fuel sender gauge assembly
- ECM
| Comes on |
DTC stored | SAE Code: P0461 | MONITOR DESCRIPTION
When
the fuel sender gauge assembly output value changes less than a
specified amount, when compared to the fuel consumption calculated from
the fuel injection volume, the ECM will detect a malfunction, illuminate
the MIL and store a DTC. MONITOR STRATEGY |

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 engine switch on (IG).
- Turn the Techstream on.
- Clear the DTCs (even if no DTCs are stored, perform the clear DTC procedure).
- Turn the engine switch off and wait for at least 30 seconds.
- Turn the engine switch on (IG) [A].
- Turn the Techstream on.
- Start the engine [B].
- Drive the vehicle at 80 km/h (50 mph) or more for 30 minutes [C].
- Enter the following menus: Powertrain / Engine / Trouble Codes [D].
- 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: P04602A.
- Check the DTC judgment result.

HINT:
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. PROCEDURE
| 1. |
INTERVIEW THE CUSTOMER | (a) Interview the customer for details about when the they refuel the vehicle.
HINT: When
the fuel tank is full, if the vehicle is repeatedly driven a short
distance and then refueled, the fuel sender gauge output value will not
change. In this case, the ECM may judge that the fuel sender gauge is
stuck and store DTC P04602A. If the vehicle was driven in this manner,
as the DTC was stored due to a user action, clear the DTCs without
performing troubleshooting and return the vehicle to the customer.
