- Remove rear seat cushion. Remove access cover to fuel pump/sending unit. Disconnect fuel pump/sending unit harness connector. See Fig 1
. Using ohmmeter, measure resistance between sending unit terminals No. 1 (White/Green wire) and No. 5 (Black wire). Resistance should be 4 ohms with a full tank and 97 ohms with an empty tank. If resistance is not as specified, replace sending unit. If resistance is okay, go to next step.
- Remove instrument cluster. See INSTRUMENT CLUSTER
under REMOVAL & INSTALLATION. Disconnect instrument cluster 14-pin connector "A". See Fig 2
. Use an ohmmeter to measure resistance between terminal No. 4 (White/Green wire) and ground. Resistance should be about the same as in step 1)
. If resistance is not as specified, repair open or short circuit in wiring harness. If resistance is as specified, reconnect instrument cluster 14-pin connector and go to next step.
- Using an ohmmeter, backprobe instrument cluster 14-pin connector between terminals No. 3 (Black wire) and No. 10 (Yellow wire), to terminal No. 4 (White/Green wire). Both readings should show about the same resistance. If readings are not as specified or indicate an open or short, replace fuel gauge.
