Component Inspection

■ Check MAPS Performance 

1. IG "OFF". Connect a GDS and oscilloscope.
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.

   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

4. Is the relationship between the MAP and the TPS correct?

   YES 

   • 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.

   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.
