| ▶ Go to "Check MAPS" as follows. |
IG "OFF" and install a scantool
Connect probe to MAPS and TPS to check signal waveform by using oscilloscope function.
ENG "ON" and monitor signal waveform during accelleration and decelleration.
Specification : Signal waveform will be displayed as follows.
Pressure(kPa) | Voltage(V) |
20 | 0.79 |
46.66 | 1.84 |
101.32 | 4.0 |
Is the relationship between the MAP and the TPS correct?
| ▶ Go to "Component Inspection" procedure. |
| ▶ Substitute with a known - good MAFS and check for proper operation. If the problem is corrected, replace MAFS and go to "Verification of Vehicle Repair" procedure. |
