Fuel Gauge Is Inaccurate
- On 1.3L engine equipped models with California emissions, turn ignition switch to LOCK position. Disconnect PCM Gray 16-pin connector. PCM Gray 16-pin connector is located behind right side of instrument panel, near glove box. On all models, disconnect fuel gauge sending unit connector, located on top of fuel tank. Using Connector Test Adapter Kit (J-35616), connect Red lead of Tester (J-33431-B) to fuel gauge sending unit connector terminal No. 1 (Yellow/Red wire) and Black lead to ground.
- Turn ignition switch to ON position. Set tester resistance dial to 120 ohms, 32 ohms, and 3 ohms. If fuel gauge does not indicate "E" at 120 ohms, one half at 32 ohms and "F" at 3 ohms, go to next step. If fuel gauge indicates "E" at 120 ohms, one half at 32 ohms and "F" at 3 ohms, check for an open in Black wire. If okay, replace fuel gauge sending unit.
- Disconnect tester. Disconnect instrument cluster White 13-pin connector. Using an ohmmeter, measure resistance between instrument cluster White 13-pin connector terminal No. 9 (Yellow/Red wire) and fuel gauge sending unit connector terminal No. 1 (Yellow/Red wire).
- If resistance is 5 ohms or more, repair open in Yellow/Red wire. If resistance is less than 5 ohms, check for high resistance in instrument cluster printed circuit. If okay, replace fuel gauge. On 1.3L engine equipped models with California emissions, if problem is not corrected, problem is related to PCM. See the TESTS W/CODES article in the ENGINE PERFORMANCE section.
