DTC No. | Detection Item | DTC Detection Condition | Trouble Area | MIL | Memory | Note |
---|---|---|---|---|---|---|
P04602A | 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). |
| 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.

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.
