- Warm up the engine to normal operating temperature.
- Measure signal waveform of MAPS and TPS together by actuating the throttle.
Specification: Signal waveform will be displayed as follows.
- Is the measured signal waveform (Comparison response of TPS with MAPS) O.K?
YES
- Check for poor connection between PCM and component: backed out terminal, improper mating, broken locks or poor terminal to wire connection. Repair as necessary and 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.
