DTC Logic
DTC DETECTION LOGIC
With the Air/Fuel Mixture Ratio Self-Learning Control, the actual mixture ratio can be brought closely to the theoretical mixture ratio based on the mixture ratio feedback signal from A/F sensor 1. The ECM calculates the necessary compensation to correct the offset between the actual and the theoretical ratios.
In case the amount of the compensation value is extremely large (the actual mixture ratio is too rich), the ECM judges the condition as the fuel injection system malfunction and illuminates the MIL (2 trip detection logic).
DTC CONFIRMATION PROCEDURE
1.PRECONDITIONING
If DTC Confirmation Procedure has been previously conducted, always perform the following before conducting the next test.
2.PERFORM DTC CONFIRMATION PROCEDURE-I
3.RESTART ENGINE
If it is difficult to start engine, the fuel injection system has a malfunction, too.
Crank engine while depressing accelerator pedal.
NOTE:
4.PERFORM DTC CONFIRMATION PROCEDURE-II
5.PERFORM DTC CONFIRMATION PROCEDURE-III
Hold the accelerator pedal as steady as possible. CAUTION: Always drive vehicle at a safe speed.
Diagnosis Procedure
1.CHECK EXHAUST GAS LEAKAGE
2.CHECK FOR INTAKE AIR LEAKAGE
Listen for an intake air leakage after the mass air flow sensor.
3.CHECK A/F SENSOR 1 INPUT SIGNAL CIRCUIT
4.CHECK FUEL PRESSURE
At idling: Approximately 350 kPa (3.57 kg/cm2, 51 psi)
5.CHECK MASS AIR FLOW SENSOR
With CONSULT
For specification, refer to EC-596, "Mass Air Flow Sensor".
With GST
6.CHECK FUNCTION OF FUEL INJECTOR
With CONSULT
With GST
7.CHECK FUEL INJECTOR
Keep fuel hose and all fuel injectors connected to fuel tube.
Check that fuel does not drip from fuel injector.
8.CHECK INTERMITTENT INCIDENT
