Fuel Injected Models
- Verify air intake system is unrestricted.
- Check EGR valve and solenoid for correct operation (if equipped).
- Check No. 1 and 2 purge control valve operation.
- Check vacuum switching valve operation.
- Check coil resistance.
- Check airflow meter for cracks.
- Check airflow operation and resistance value.
- Check atmospheric pressure sensor.
- Check Variable Resonance Induction System (VRIS) for correct operation (MPV 3.0L and MX-3 1.8L).
- Check Variable Inertia Charge System (VICS) for correct operation (Protege DOHC and 929).
- Verify crank angle sensor (permanent magnet type) has correct resistance values.
- Check A/C cut-off system (if equipped).
- Ensure fuel system pressure is correct. Use ohmmeter to verify fuel injector terminal resistance.
- Check turbo system (if equipped) for damage and wear. Turbo system inspection should include following components. - Air By-Pass Valve - Engine Control Unit (ECU) - Intake Air Thermosensor In Airflow Meter - Knock Sensor And Knock Control Unit - Turbo Wastegate Solenoid Valve
