Component Inspection

1. Check MAPS Performance
(1) IG "OFF" and install scantool.
(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.
A. Specification :













(4) Is the measured signal waveform (MAP/TPS Rationality) O.K?
YES
> Go to "Verification of Vehicle Repair" procedure.
NO
> Substitute with a known - good MAPS and check for proper operation. If the problem is corrected, replace MAPS and go to "Verification of Vehicle Repair" procedure.
