DTC P0460: Fuel Level Sensor Function (Slosh): Procedure
- Disconnect fuel pump assembly harness connector located behind access cover, under rear seat. Turn ignition on. Measure voltage between ground and fuel pump assembly harness connector terminal No. 2 (Green wire). See Figure. If voltage is about 5 volts, go to next step. If voltage is not about 5 volts, repair open or short in Green wire between instrument cluster, ECM and fuel pump assembly, then retest system. See WIRING DIAGRAMS article.
- Turn ignition off. Check continuity between body ground and fuel pump assembly harness connector terminal No. 5 (Black wire). Continuity should exist. Also check circuit for short to voltage. See WIRING DIAGRAMS article. Repair circuit as necessary and retest system. If ground circuit is okay, go to next step.
- Disconnect ECM harness connector. See Figure. Check continuity of Green wire between fuel pump assembly harness connector terminal No. 2 and ECM harness connector terminal No. 83. See Figure and Figure
. Also check circuit for short to voltage. Repair circuit as necessary and retest system. If circuit is okay, go to next step.
- Remove fuel pump assembly from fuel tank. Measure resistance between fuel level sensor terminals No. 2 and 5, with sensor at specified positions. See FUEL LEVEL SENSOR RESISTANCE table. If resistance is as specified, go to next step. If resistance is not as specified, replace fuel level sensor and retest system.
- No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
