DTC P0461: Fuel Level Sensor (Gauge) Circuit Performance Problem (Esteem 1.8L)
- If DTC P0463 is present, perform diagnosis for that DTC first. See DTC P0463: FUEL LEVEL SENSOR (GAUGE) CIRCUIT HIGH INPUT . If DTC P0463 is not present, connect scan tool to DLC. Turn ignition on. Check fuel level on scan tool. Add one gallon (3.7L) of fuel to tank. Recheck fuel level. If fuel level increases on scan tool, fuel level sensor is okay. If fuel level does not increase, go to next step.
- Turn ignition off. Disconnect fuel level sensor connector. Check for good terminal contact at sensor connector terminal No. 4 (Pink/Blue wire). Repair as necessary. If terminal contact is okay, measure resistance between fuel level sensor terminals. If resistance changes within 3-120 ohm range when one gallon (3.7L) of fuel is added to tank, go to next step. If resistance does not change when one gallon (3.7L) of fuel is added to tank, check Pink/Blue wire for an open circuit. If wire is okay, replace fuel level sensor.
- Disconnect PCM connectors. Check for good terminal contact at PCM connector E91, terminal No. 8 (Pink/Blue wire). Repair as necessary. If wiring is okay, disconnect fuel level sensor connector. Gauge should indicate empty. Connect jumper wire between connector terminals No. 4 (Pink/Blue wire) and No. 2 (Black wire). Gauge should indicate full. If gauge operates as specified, replace PCM. If gauge does not operate as specified, check for short or open circuit in Pink/Light Blue or Black wire
