1A-56 Engine General Information and Diagnosis:
DTC P0103: Mass Air Flow Circuit High Input
S4RS0A1104018
Wiring Diagram
8
MAF sensor signal circuit check
1) Measure resistance between “GRN/BLK” wire terminal
of MAF and IAT sensor connector and “C37-26” terminal
of ECM connector.
Is resistance below 3
:
?
Go to Step 9.
“GRN/BLK” wire is open
or high resistance
circuit.
9
MAF sensor output signal check
1) Connect connectors to MAF and IAT sensor and ECM
with ignition switch turned OFF.
2) Measure voltage between “C37-26” and “C37-27”
terminals of ECM connector referring to “Mass Air Flow
(MAF) and Intake Air Temperature (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.
