Diagnostic Procedures

  1. Perform On-Board Diagnostic II (OBD-II) system check. See SELF-DIAGNOSTICS - INTRODUCTION article. Go to next step.
  2. Turn ignition on. Compare fuel level reading on scan tool with vehicle fuel gauge. If readings are about the same, go to next step. If readings are not about the same, go to step  5.
  3. Record fuel gauge reading. Turn ignition off. Disconnect PCM harness connectors. Turn ignition on. If vehicle fuel gauge reading changes, go to next step. If fuel gauge reading does not change, go to step  5.
  4. Turn ignition off. Disconnect fuel tank level sensor connector. Using a fused jumper wire, jumper fuel level input to fuel level sensor ground. Turn ignition on. If the scan tool and fuel gauge indicate 0 percent (empty), go to next step. If scan tool and fuel gauge readings do not indicate 0 percent, go to step  6.
  5. Replace fuel tank level sensor. Go to step  7.
  6. Replace and reprogram PCM using required equipment. See PROGRAMMING . Retest system.
  7. Using scan tool, clear DTC information. Start engine and idle to normal operating temperature. Operate the vehicle within the conditions for setting DTC P0461. If scan tool indicates diagnostic RAN AND PASSED, system is okay. If DTC does not indicate system passed, go back to step  2.
