1. Measure resistance between the No. 1 and No. 2 terminals with the float at E (EMPTY), 1/2 (HALF FULL), and F (FULL) positions. If you do not get the following readings, replace the fuel gauge sending unit.
   Float Position | F 31.2 mm(1.2 in.) | 1/2 96.6 mm(3.8 in.) | LOW 157 mm(6.2 in.) | E 169.9 mm(6.7 in.)
   Resistance (Ω) | 19 to21 | 197.4 to207.4 | 525.8 to717.4 | 770 to790
NOTE: Remove the No. 15 BACK UP (40 A) fuse from the under-hood fuse/relay box for at least 10 seconds after completing troubleshooting, otherwise it may take up to 20 minutes for the fuel gauge to indicate the correct fuel level. |
