If there is a deviation from the standard value, check the following items: • Diagnosis output • Fuel pressure • Injector • Ignition coil, spark plug cable, spark plug • EGR control system • Evaporative emission control system • Compression pressure NOTE:
Replace the three way catalyst when the CO and E8. CHECK EXHAUST GAS M6020600800096 EGR CONTROL VALVE CHECK 1. Remove the EGR valve and inspect for sticking, carbon deposits, etc. If found clean with a suitable 2. Connect a hand vacuum pump to the EGR valve. vacuum is maintained. 4. Apply a vacuum and check the passage of air by blowing through one side of the EGR passage. 5. Replace the gasket, and tighten to the specified torque. Tightening torque: 21 ± 4 N⋅m <4G1> 20 ± 2 N⋅m <4G6> EGR CONTROL SOLENOID VALVE NOTE: When disconnecting the vacuum hose, valve. 2. Disconnect the harness connector. 3. Connect a hand vacuum pump to nipple (A) of the solenoid valve. 4. Check air tightness by applying a vacuum with voltage applied directly from the battery to the 5. Measure the resistance between the terminals of the solenoid valve.
