5V ENGINE PRESSURE SENSOR SUPPLY CIRCUIT TEST

N OT E
Use this procedure if another procedure
has directed you here or if diagnostic code
262-03 (5V Sensor dc Power Supply Short
to +Batt) or diagnostic code 262-04 (5-volt
Sensor dc Power Supply Short to Ground)
is active.
Electronic control module (ECM) supplies
regulated +5 VDC to the following sensors:
a.
J201/P201 Engine Oil Pressure
b.
J200/P200 Boost Pressure
c.
J40/P40 Throttle
427-B0665
Supply or +5V engine pressure sensor is
routed from ECM, through ECM engine
harness connector terminal 26, to terminal
A of each pressure sensor connector. Sup-
ply voltage is 5.0 0.5 VDC.
+5V short circuit diagnostic code is probably caused by short circuit or open circuit in harness. Next probable
cause is sensor and least probable cause is ECM.
