Fuel and Emissions - Testing & Troubleshooting

NOTE: If you were referred to this procedure from a troubleshooting procedure, test the fuel pressure under the same conditions the malfunction occurred (engine speed, load, throttle position, etc.).

  1. Disconnect the quick-connect fitting and attach the fuel pressure gauge set. Check for leaks with the gauge set attached
  2. Start the engine, and let it idle.
    • If the engine starts, go to step 3 and read the fuel pressure gauge.
    • If the pump does not run, do the fuel pump circuit troubleshooting.
  3. Read the fuel pressure gauge. The pressure should be: 390-440 kPa (3.98-4.49 kgf/cm2, 56.6-63.8 psi)
    • If the pressure is OK, the test is complete.
    • If the pressure is out of specification, replace the fuel pressure regulator - Refer to: Fuel Tank Unit Disassembly and Reassembly (2WD), or Fuel Tank Unit Disassembly and Reassembly (AWD) and the fuel filter - Refer to: Fuel Tank Unit Disassembly and Reassembly(2WD), or Fuel Tank Unit Disassembly and Reassembly (AWD), then recheck the fuel pressure.

LOW FUEL INDICATOR TEST

Test

1. Low Fuel Indicator - Test

  1. Do the gauge self-diagnostic test.
    • If the low fuel indicator flashes, go to step 2.
    • If the low fuel indicator does not flash, replace the gauge control module.
  2. Check for body electrical system DTCs.
    • If any DTCs are indicated, do the indicated DTC's troubleshooting.
    • If no DTCs are indicated, go to step 3.
  3. Do the fuel gauge sending unit test and the secondary fuel gauge sending unit test.
    • 2WD: Test the fuel gauge sending unit - Refer to: Fuel Gauge Sending Unit Test (2WD), or Fuel Gauge Sending Unit Test (AWD)
    • AWD: Test the fuel gauge sending unit - Refer to: Fuel Gauge Sending Unit Test (2WD), or Fuel Gauge Sending Unit Test (AWD) and the secondary fuel gauge sending unit
