Component Inspection

  1. MAPS performance test
    1. IG "OFF"
    2. Connect scantool to Data Link Connector (DLC) and select "Oscilloscope" then, connect probes to output signal lines of MAPS and TPS. Turn engine "ON" and monitor the waveforms accelerating or decelerating
    3. Start engine and monitor signal waveform during acceleration and deceleration.
