- READ VALUE USING TECHSTREAM (FUEL INPUT)
- Connect the Techstream to the DLC3.
- Turn the ignition switch to ON.
- Turn the Techstream on.
- Enter following menus: Body Electrical / Combination Meter / Data List.
- Check the values by referring to the table below.
Combination Meter
COMBINATION METER REFERENCE CHARTTester Display Measurement Item/Range Normal Condition Diagnostic Note Fuel Input Fuel input signal Min.: 0, Max.: 127.5 Fuel gauge indicates (E): 5.5 (L) - Fuel gauge indicates (1/2): 27.5 (L) Fuel gauge indicates (F): 49.5 (L) OK:
Fuel value signal displayed on the Techstream is almost the same as fuel receiver gauge indication.
NG: REPLACE COMBINATION METER (See REMOVAL )
OK: Go to next step
- CHECK HARNESS AND CONNECTOR (COMBINATION METER - FUEL SENDER GAUGE ASSEMBLY)
- Disconnect the E46 and L17 connectors.
- Measure the resistance according to the value(s) in the table below.

OK: Go to next step
- INSPECT FUEL SENDER GAUGE ASSEMBLY
- Remove the fuel sender gauge assembly.
- Check that the float moves smoothly between E and F.
- Measure the resistance according to the value(s) in the table below.
