DTC P0460-00: Fuel Level Sensor Circuit Malfunction: Notes

DTC P0460:00 DETECTION CONDITION AND POSSIBLE CAUSE

DTC P0460:00	Fuel level sensor circuit malfunction
DETECTION CONDITION	The PCM monitors the fuel tank level sensor output signal. If the difference between maximum and minimum value of input signal is 25 % or more for 14 s, the PCM determines that there is a fuel level sensor circuit malfunction. MONITORING CONDITIONS The following DTCs are not detected: Fuel gauge sender unit: P0462:00, P0463:00 Diagnostic support note This is a continuous monitor (CCM). The check engine light illuminates if the PCM detects the above malfunction condition in two consecutive drive cycles or in one drive cycle while the DTC for the same malfunction has been stored in the PCM. PENDING CODE is available if the PCM detects the above malfunction condition during first drive cycle. FREEZE FRAME DATA/Snapshot data is available. DTC is stored in the PCM memory.
FAIL-SAFE FUNCTION	Not applicable
POSSIBLE CAUSE	Instrument cluster malfunction Incorrectly installed fuel gauge Fuel level input signal circuit malfunction Fuel gauge sender unit connector or terminals malfunction Fuel gauge sender unit (SUB) connector or terminals malfunction BCM connector or terminals malfunction Short to power supply in wiring harness between the following terminals: Fuel gauge sender unit terminal D-BCM terminal 2Q Fuel gauge sender unit terminal C-BCM terminal 2R Fuel gauge sender unit (SUB) terminal A-BCM terminal 2T Fuel gauge sender unit (SUB) terminal C-BCM terminal 2R Short to ground in wiring harness between the following terminals: Fuel gauge sender unit terminal D-BCM terminal 2Q Fuel gauge sender unit terminal C-BCM terminal 2R Fuel gauge sender unit (SUB) terminal A-BCM terminal 2T Fuel gauge sender unit (SUB) terminal C-BCM terminal 2R Fuel gauge sender unit signal circuit and ground circuit are shorted to each other Fuel gauge sender unit (SUB) signal circuit and ground circuit are shorted to each other Open circuit in wiring harness between the following terminals: Fuel gauge sender unit terminal D-BCM terminal 2Q Fuel gauge sender unit terminal C-BCM terminal 2R Fuel gauge sender unit terminal (SUB) A-BCM terminal 2T Fuel gauge sender unit terminal (SUB) C-BCM terminal 2R Fuel gauge sender unit malfunction Fuel gauge sender unit (SUB) malfunction PCM malfunction
