DTC Troubleshooting
NOTE
If the vehicle runs under fuel deficient condition (such as a condition in which the fuel pump is unable
to draw fuel properly), DTC of misfire may possibly be detected due to fuel pressure drop even though
there is no abnormal condition existing in the Engine and Emission System.
Therefore, if the DTC still cannot be detected with “Trouble Symptom Confirmation” executed in
accordance with “Engine and Emission Control System Check” the possible cause may be due to a
running condition under insufficient fuel supply at the time of detecting DTC of misfire.

Step Action Yes No
1Was “Engine and Emission Control System Check”
performed?Go to Step 2. Go to “Engine and
Emission Control
System Check”.
2Does fuel level meter indicate “E” level (empty)?Add fuel and recheck. Go to Step 3.
3Fuel quality check
1) Check that there is fuel of good quality in the fuel tank.
Is it OK?Go to Step 4. Clean in fuel system
circuit and change fuel.
4Ignition system check
1) Check spark plug and ignition spark of cylinder where
misfire occurs, referring to “Spark Plug Inspection in
Section 1H” and “Ignition Spark Test in Section 1H”.
Are they in good condition?Go to Step 5. Faulty ignition coil, wire
harness, spark plug or
other system parts.
5Fuel injector circuit check
1) Using sound scope, check each injector operating sound
at engine cranking or idling.
Do all injectors make operating sound?Go to Step 6. Check coupler
connection and wire
harness of injector not
making operating sound
and injector itself. If OK,
substitute a known-
good ECM and recheck.
6Fuel pressure check
1) Check fuel pressure referring to “Fuel Pressure Check”.
Is check result satisfactory?Go to Step 7. Repair or replace fuel
system.
7Fuel injector check
1) Check fuel injector(s) referring to “Fuel Injector
Inspection in Section 1G”.
Is check result satisfactory?Go to Step 8. Replace defective
injector.
8Ignition timing check
1) Check ignition timing referring to “Ignition Timing
Inspection in Section 1H”.
Is check result satisfactory?Go to Step 9. Check related sensors.
9EGR system check
1) Check EGR system referring to “EGR System Inspection
(If Equipped) in Section 1B”.
Is check result satisfactory?Go to Step 10. Repair or replace EGR
system.
10Exhaust system check
1) Check exhaust system for exhaust gas clogged.
Is it OK?Go to Step 11. Repair clogged of
exhaust system.
