ANCE B1
(Air-fuel ratio imbalance bank
1) ECM detects a lean/rich air fuel ratio state in any
cylinder for a specified length of time. • Fuel injector
• Exhaust gas leaks
• Incorrect fuel pressure
• Mass air flow sensor
• Intake air leaks
• Lack of fuel
• Incorrect PCV hose connection
• Improper spark plug
• Insufficient compression
• The fuel injector circuit is open or
shorted

6.CHECK FUNCTION OF FUEL INJECTOR-2
CAUTION:
Perform the following procedure in a place with no combustible objects and good ventilation.
1. Turn ignition switch OFF.
2. Confirm that the engine is cooled down and t here are no fire hazards near the vehicle.
3. Disconnect all fuel injector harness connectors.
4. Remove fuel tube assembly. Refer to EM-40, "
Removal and Installation".
Keep fuel hose and all fuel injectors connected to fuel tube.
5. Disconnect all ignition coil harness connectors.
6. Prepare pans or saucers under each fuel injector.
7. Crank engine for approximately 3 seconds.
Is the inspection result normal?
YES >> GO TO 7.
NO >> Replace fuel injector. Refer to EM-40, "
Removal and
Installation".
7.CHECK FUNCTION OF IGNITION COIL-1
CAUTION:
Perform the following steps in a well-ventilated area with no combustibles.
1. Turn ignition switch OFF.
2. Remove fuel pump fuse from IPDM E/R to release fuel pressure. NOTE:
CONSULT must not be used to release fuel pressure. It develops again during the following steps,
if released by using CONSULT.
3. Start the engine.
4. After an engine stall, crank the engine two or three times to release all the fuel pressure.
5. Turn ignition switch OFF.
6. Disconnect all the harness connectors of ignition coil to prevent electric discharge from occurring in igni-
tion coil.
7. Remove ignition coil assembly and spark plug of cylinder. Refer to EM-47, "
Removal and Installation".
8. Crank engine for 5 seconds or more to remove combustion gas in the cylinder.
9. Connect spark plug and harness connector to ignition coil.
10. Allow a 13-17mm (0.52-0.66 in) spacing between spark plug and grounded metal portion as shown in the figure to fix the ignition
coil with a rope or an equivalent.
11. Crank the engine for approximately 3 seconds to see if sparking occurs between spark plug and the grounded metal portion.
CAUTION:
• The discharge voltage becomes 20 kV or higher. There-fore, always stay away from the spark plug and ignition
coil at least 50 cm (19.7 in) during the inspection.
• Leaving a space of more than 17mm (0.66 in) may damage the ignition coil.
NOTE:
When the gap is less than 13 mm (0.52 in), a the sp ark might be generated even if the coil is mal-
functioning.
Is the inspection result normal?
YES >> GO TO 8.
NO >> GO TO 10.
8.CHECK COMPRESSION PRESSURE • Fuel should be sprayed evenly for each fuel injector.
• Fuel must not drip from the tip of fuel injector.
