Inspection Procedure

  1. READ VALUE USING TECHSTREAM (FUEL INPUT) 
    1. Connect the Techstream to the DLC3.
    2. Turn the engine switch on (IG).
    3. Turn the tester on.
    4. Enter following menus: Body/Combination Meter/Data List.
    5. Check the values by referring to the table below.

      Combination Meter: 

      COMBINATION METER - DATA LIST

      Tester Display Measurement Item/Range Normal Condition Diagnostic Note
      Fuel Input Fuel input signal/Min.: 0, Max.: 127.5 Fuel gauge indicates (E): 7.5 (L)
      Fuel gauge indicates (1/2): 35.0 (L)
      Fuel gauge indicates (F): 62.9 (L)      		 -

      Result Proceed to
      Fuel level data can be displayed on the Techstream and DTC B1500 is output. A
      Fuel level data cannot be displayed on the Techstream. B

      B: Go to step 2 

      A: REPLACE COMBINATION METER ASSEMBLY  (See REMOVAL  )

  2. INSPECT COMBINATION METER ASSEMBLY 
    1. Disconnect the E1 connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      E1-19 (FE) - E1-34 (FR) Always 13.5 to 414.5 Ω

      NG: Go to step 3

      OK: REPLACE COMBINATION METER ASSEMBLY  (See REMOVAL  )

  3. CHECK HARNESS AND CONNECTOR (COMBINATION METER ASSEMBLY - FUEL SENDER GAUGE ASSEMBLY) 
    1. Disconnect the fuel sender gauge assembly connector.
    2. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      E1-34 (FR) - 2 Always Below 1 Ω
      E1-34 (FE) - Body ground Always 10 kΩ or higher
      E1-19 (FE) - 1 Always Below 1 Ω
      E1-19 (FE) - Body ground Always 10 kΩ or higher

      NG: REPAIR OR REPLACE HARNESS OR CONNECTOR

      OK: Go to next step 

  4. INSPECT FUEL SENDER GAUGE ASSEMBLY 
    1. Remove the fuel sender gauge assembly (See REMOVAL for 2GR-FE, See REMOVAL for 1AR-FE).
    2. Check that the float moves smoothly between E and F.
    3. Measure the resistance according to the value(s) in the table below.

      Standard resistance 

      RESISTANCE SPECIFICATION

      Tester Connection Condition Specified Condition
      1 - 2 Float level is F (upper) 3.0 to 5.0 Ω
      1 - 2 Float level is between F (upper) and E (lower) 3.0 to 111.0 Ω (Gradually changes)
      1 - 2 Float level is E (lower) 109.0 to 111.0 Ω

      Result Proceed to
      OK A
      NG (for 2GR-FE) B
      NG (for 1AR-FE) C

      B: REPLACE FUEL SENDER GAUGE ASSEMBLY (for 2GR-FE)  (See REMOVAL )

      C: REPLACE FUEL SENDER GAGE ASSEMBLY (for 1 AR-FE)  (See REMOVAL )
