Sensor 5 V power source circuit check
1) Disconnect connectors from ECM, TP sensor, MAP
sensor, A/C refrigerant pressure sensor (if equipped with
A/C), electric load current sensor (for J20 engine) and
accelerator pedal position (APP) sensor with ignition
switch turned OFF.
2) Measure each resistance between “C37-14”, “E23-56”,
“E23-54” and “C37-53” terminal of ECM connector and
vehicle body ground.
Is each resistance infinity?
Check internal short
circuit of TP sensor,
MAP sensor, A/C
refrigerant pressure
sensor (if equipped with
A/C), electric load
current sensor (for J20
engine) and/or
accelerator pedal
position (APP) sensor.
“GRY/RED”, “WHT”
and/or “ORN/BLU” wire
is shorted to ground
circuit.
