ENG "ON" and monitor signal waveform during acceleration and deceleration.
Specification : Signal waveform will be displayed as follows.
Pressure(kPa) | Voltage(V) |
20 kPa (2.9 psi) | 0.79 |
46.66 kPa (6.76 psi) | 1.84 |
101.32 kPa (14.69 psi) | 4.0 |
IG "OFF". Connect a GDS and oscilloscope.
Connect probe to MAPS and TPS to check signal waveform by using oscilloscope function.

Is the relationship between the MAP and the TPS correct?
 | ▶ Substitute with a known - good PCM and check for proper operation. If the problem is corrected, replace PCM and go to "Verification of Vehicle Repair" procedure. |
 | ▶ 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. |
