Test TC-151B - Fuel Level Unit No Change Over Miles
NOTE:
For connector terminal idnetification, see CONNECTOR IDENTIFICATION DIRECTORY table. For wiring diagram, see WIRING DIAGRAMS article.
- If fuel gauge reads more than 1/8 tank and low fuel light is on, replace fuel level sending unit. Perform TEST VER-2A . If fuel gauge does not read more than 1/8 tank and low fuel light is not on, go to next step.
- Turn ignition off. Disconnect Powertrain Control Module (PCM) connector. Turn ignition on. Using scan tool in voltmeter mode, check voltage of PCM connector terminal No. 23 (Yellow/Dark Blue wire). If voltage is .5-4.7 volts, go to next step. If voltage is not .5-4.7 volts, replace fuel level sending unit. Perform TEST VER-2A .
- Remove fuel level sending unit from fuel tank. Inspect fuel level sending unit for proper operation. If fuel tank sending unit is okay, replace PCM. Perform TEST VER-2A . If fuel tank sending unit is not okay, replace fuel tank sending unit. Perform TEST VER-2A .
