Engine General Information and Diagnosis: 1A-61
Step
Action
Yes
No
1
Was “Engine and Emission Control System Check”
performed?
Go to Step 2.
Go to “Engine and
Emission Control
System Check: ”.
2
MAP sensor and its circuit check
1) Connect scan tool to DLC with ignition switch turned
OFF.
2) Turn ON ignition switch.
3) Check intake manifold pressure displayed on scan tool.
Is it 0 kPa (0 in.Hg)?
Go to Step 3.
Intermittent trouble.
Check for intermittent
referring to “Intermittent
and Poor Connection
Inspection: in Section
00”.
3
MAP sensor power supply voltage check
1) Disconnect connector from MAP sensor with ignition
switch turned OFF.
2) Check for proper connection of MAP sensor at “GRY/
RED”, “RED/BLK” and “ORN” wire terminals.
3) Turn ON ignition switch, measure voltage between
engine ground and “GRY/RED” wire terminal of MAP
sensor connector.
Is voltage 4 – 6 V?
Go to Step 5.
Go to Step 4.
4
MAP sensor power supply circuit check
1) Disconnect connectors from TP sensor and A/C
refrigerant pressure sensor with ignition switch turned
OFF.
2) Turn ON ignition switch, measure voltage between
engine ground and “GRY/RED” wire terminal of MAP
sensor connector.
Is voltage 4 – 6 V?
Faulty TP sensor and/or
A/C refrigerant pressure
sensor.
“GRY/RED” wire is
shorted to ground
circuit.
If wires are OK,
substitute a known-
good ECM and recheck.
5
MAP sensor signal circuit check
1) Measure voltage between “RED/BLK” wire terminal of
MAP sensor connector and engine ground.
Is voltage 4 – 6 V?
Go to Step 7.
Go to Step 6.
6
MAP sensor signal circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure resistance between “C37-53” terminal of ECM
connector and vehicle body ground.
Is resistance infinity?
Go to Step 7.
“RED/BLK” wire is
shorted to ground
circuit.
7
MAP sensor output signal check
1) Check MAP sensor according to “Manifold Absolute
Pressure (MAP) Sensor Inspection: in Section 1C”.
Is it in good condition?
Substitute a known-
good ECM and recheck.
Faulty MAP sensor.
