For component location, see COMPONENT LOCATIONS  . For connector terminal identification, see CONNECTOR IDENTIFICATION  .

  1. Remove fuel level sensor/FTT sensor. See FUEL PUMP MODULE under FUEL SYSTEMS in REMOVAL & INSTALLATION - EXCEPT I35 & QX4 article. Measure resistance between sensor terminals No. 4 and 5. With float at EMPTY position, resistance should be about 79-85 ohms. With float at FULL position, resistance should be about 2-3 ohms. If resistance is as specified, go to next step. If resistance is not as specified, replace fuel level sensor/FTT sensor.
  2. Remove fuel level sensor unit (sub). Measure resistance between sensor terminals No. 1 and 2. With float at EMPTY position, resistance should be about 41-45 ohms. With float at FULL position, resistance should be about 2-3 ohms. If resistance is as specified, go to next step. If resistance is not as specified, replace fuel level sensor unit (sub).
  3. No problem is indicated at this time. Problem may be intermittent. See INTERMITTENTS in TROUBLE SHOOTING - NO CODES article.
