TERMINAL AND CONNECTOR INSPECTION
E1AD95A0
Refer to DTC P1106.
POWER CIRCUIT INSPECTION
EC3C4E38
1.
IG "OFF"
2.
Disconnect MAPS connector.
3.
IG "ON"
4.
Measure the voltage between terminal 2 of MAPS harness connector and ground.
Specification : Approx. 5V
5.
Is the measured voltage within specification ?
YES
▶ Go to "Signal Circuit Inspection" of MAPS.
NO
▶ After repairing open or short to ground in harness and go to "Verification of Vehicle Repair"
SIGNAL CIRCUIT INSPECTION
E46CA26A
1.
Check short to ground in harness
1)
IG "OFF"
2)
Disconnect MAPS and PCM connector.
3)
Measure the resistance between terminal 1 of MAPS harness connector and ground.
Specification : Infinite
4)
Is the measured resistance within the specification?
YES
▶ Go to "Check open in the harness" of MAPS.
NO
▶ After repairing short to ground in circuits and go to "Verification of Vehicle Repair"
2.
Check open in the harness
1)
IG "OFF"
2)
Disconnect MAPS and PCM connector.
3)
Measure the resistance between terminal 1 of MAPS harness connector and terminal C30-B (8) of PCM harness
connector

FUEL SYSTEM
Specification : Approx. below 1 Ω
4)
Is the measured resistance within the specification?
YES
▶ Go to "Component Inspection" of MAPS.
NO
▶ Repair open in the harness and go to "Verification of Vehicle Repair".
COMPONENT INSPECTION

1.
MAPS performance test
1)
IG "OFF"
2)
Connect scantool to Data Link Connector(DLC) and select "Oscilloscope" then, connect probes to output signal
lines of MAPS and TPS.Turn engine "ON" and monitor the waveforms accelerating or decelerating
3)
ENG "ON" and monitor signal waveform during accelleration and decelleration.

2.
Check PCM
1)
IG "OFF" disconnect MAPS connector
2)
Connect Scantool and IG "ON" & ENG "OFF"
3)
Select simulation function on scantool.
4)
Simulate voltage at terminal 1 of MAPS harness connector.

5)
Does the output voltage response to the change of signal by simulation?
YES
▶ Thoroughly check connectors for looseness, poor connection, bending, corrosion, contamination, deteriora-
tion, or damage. Repair or replace if necessary and go to "Verification of Vehicle Repair" procedure
NO
▶ 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.
NOTE
There is a memory reset function on scantool that can erase optional parts automatically detected and memorized
by PCM.Before or after testing PCM on the vehicle, use this function to reuse the PCM on the others
