DTC P0461 [13B-MSP]

DTC REFERENCE CHART

DTC P0461

Fuel gauge sender unit (main) circuit range/performance problem

DETECTION CONDITION

The PCM monitors the fuel tank level difference before and after the PCM-calculated fuel consumption has reached more than 21 L {22.2 US qt, 18.5 lmp qt} . If the difference is less than 5% , the PCM determines that there is a fuel gauge sender unit (main) circuit range/performance problem.

Diagnostic support note

This is a continuous monitor (CCM.)
The MIL 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 the first drive cycle.
FREEZE FRAME DATA is available.
The DTC is stored in the PCM memory.

POSSIBLE CAUSE

Instrument cluster malfunction
Fuel gauge sender unit (main) malfunction
PCM malfunction

DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED Has FREEZE FRAME DATA been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2	VERIFY RELATED REPAIR INFORMATION AVAILABILITY Verify related Service Bulletins and/or on-line repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT INSTRUMENT CLUSTER Perform the "INSTRUMENT CLUSTER INPUT/OUTPUT CHECK MODE". (See INSTRUMENT CLUSTER INPUT/OUTPUT CHECK MODE .) Is there any malfunction?	Yes	Repair or replace the malfunctioning part, then go to Step 5.
3		No	Go to the next step.
4	INSPECT FUEL GAUGE SENDER UNIT Inspect the fuel gauge sender unit (main.) (See FUEL GAUGE SENDER UNIT INSPECTION .) Is there any malfunction?	Yes	Replace the fuel gauge sender unit (main), then go to the next step. (See FUEL GAUGE SENDER UNIT REMOVAL/INSTALLATION .)
4		No	Go to the next step.
5	VERIFY TROUBLESHOOTING OF DTC P0461 COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. Start the engine. Drive the vehicle under the FREEZE FRAME DATA condition. Is the PENDING CODE same as DTC present?	Yes	Replace the PCM, then go to the next step. (See PCM REMOVAL/INSTALLATION [13B-MSP] .)
5		No	Go to the next step.
6	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [13B-MSP] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [13B-MSP] .)
6		No	DTC troubleshooting completed.
