Check TPS
Visually check that TPS is contaminated by foreign materials, deformed, or damaged
Has a problem been found ?
YES
Go to "Check MAPS Performance" as follows.
NO
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.
Check MAPS Performance
IG "OFF" and install scatool.
Connect probe to MAPS and TPS to check signal waveform by using oscilloscope function.
ENG "ON" and monitor signal waveform during accelleration and decelleration.
Specificaton :
Pressure (kPa) | 20 | 35 | 60 | 95 | 101.32 |
Voltage (V) | 0.789 | 1.382 | 2.369 | 3.75 | 4 |
Tolerance (V) | ± 0.045 |
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.
