Component Inspection

  1. Check TPS
    1. Visually check that TPS is contaminated by foreign materials, deformed, or damaged
    2. Has a problem been found?

      YES

      1. Substitute with a known - good TPS and check for proper operation.

        If the problem is corrected, replace TPS and go to "VERIFICATION OF VEHICLE REPAIR " procedure.

      NO

      1. Go to "Check MAPS Performance" as follows.
  2. Check MAPS Performance
    1. IG "OFF" and install scan tool.
    2. Connect probe to MAPS and TPS to check signal waveform by using oscilloscope function.
    3. ENG "ON" and monitor signal waveform during acceleration and deceleration.

    4. Is the measured signal waveform (MAP/TPS Rationality) O.K?

      YES

      NO

      • Substitute with a known - good MAPS and check for proper operation. If the problem is corrected, replace MAPS and go "VERIFICATION OF VEHICLE REPAIR " procedure.
