NSX-T V6-3.2L DOHC (VTEC) (1997)
Fuel Gauge: Testing and Inspection
NOTE: See the fuel gauge circuit diagram.
1. Before testing, check the No. 5 (15 A) fuse in the under-dash fuse box.
2. Remove the rear bulkhead panel behind the driver's seat, then remove the access panel.
Fuel Gauge-Gauge Test
3. Disconnect the 3P connector from the fuel gauge sending unit.
4. Connect the voltmeter positive probe to the B (YEL/WHT) terminal and the negative probe to the C (BLK) terminal, then turn the ignition switch
ON (II). There should be between 5 and 8 V.
-
If the voltage is as specified, go to step 5.
-
If the voltage is not as specified, check for:
-
An open in the YEL, YEL/WHT or BLK wire.
-
Poor ground (G403).
5. Turn the ignition switch OFF. Connect a jumper wire between the B (YEL/WHT) and A (BLK) terminals.
CAUTION: Do not apply battery voltage to the terminals; it will damage the fuel gauge.
6. Turn the ignition switch ON (II). Check that the pointer of the fuel gauge starts moving toward the "F" mark.
CAUTION: Turn the ignition switch OFF before the pointer reaches the "F" mark on the gauge dial; if you don't, you may cause damage to the
fuel gauge.
-
If the pointer of the fuel gauge does not move at all, replace the gauge.
-
If the fuel gauge is OK, check the sending unit.
