Wiring Diagram
DTC Detecting Condition and Trouble Area6
MAF sensor signal circuit check
1) Disconnect connectors from ECM with ignition switch
turned OFF.
2) Measure voltage between “GRY/BLK” wire terminal of MAF and IAT sensor connector and engine ground.
Is voltage 0 V? Go to Step 7. “GRY/BLK” wire is
shorted to other circuit.
7 MAF sensor output signal check
1) Connect connector to MAF and IAT sensor and ECM
with ignition swit ch turned OFF.
2) Measure voltage between “C37-26” and “C37-27” terminal of ECM connector referring to “MAF and IAT
Sensor On-Vehicle Inspection in Section 1C”.
Is each value within specified range? Substitute a known-
good ECM and recheck.
Faulty MAF and IAT
sensor.

DTC detecting condition Trouble area
• Difference between Max. manifold absolute pressure value and Min. manifold pressure value is less than 1.3
kPa (0.19 psi) when engine running at idle speed.
• Difference between barometric pressure value and manifold pressure value is less than 33.3 kPa (4.83 psi)
for 5 sec. at 2000 r/mini. or more.
(2 driving cycle detection logic) • Manifold absolute pressure sensor
• Manifold absolute pressure sensor vacuum passage
