  8. Rev up the engine two or three times and make sure that idle speed and ignition timing are within the specifications.
    IDLE SPEED AND IGNITION TIMING SPECIFICATIONS

    ITEM SPECIFICATION
    Idle speed M/T: 700 +/- 50 RPM
    Idle speed A/T: 700 +/- 50 RPM (in P or N position)
    Ignition timing M/T: 15 +/- 5° BTDC
    Ignition timing A/T: 15 +/- 5° BTDC (in P or N position)

Without CONSULT-II 

NOTE:
  • It is better to count the time accurately with a clock.
  • It is impossible to switch the diagnostic mode when an accelerator pedal position sensor circuit has a malfunction.
  1. Perform "ACCELERATOR PEDAL RELEASED POSITION LEARNING ".
  2. Perform "THROTTLE VALVE CLOSED POSITION LEARNING ".
  3. Start engine and warm it up to normal operating temperature.
  4. Check that all items listed under the topic PREPARATION (previously mentioned) are in good order.
  5. Turn ignition switch OFF and wait at least 10 seconds.
  6. Confirm that accelerator pedal is fully released, turn ignition switch ON and wait 3 seconds.
  7. Repeat the following procedure quickly five times within 5 seconds.
    1. Fully depress the accelerator pedal.
    2. Fully release the accelerator pedal.
