Test Step 1. Check For Active +5 V
Sensor Supply Diagnostic Codes.
A. Connect the electronic service tool to the
diagnostic connector.
B. Turn the keyswitch to the ON position. Wait at
least 15 seconds for activation of the diagnostic
codes.
C. Verify if any of the following diagnostic codes are
active:
•
262-03 5 Volt Sensor Supply, voltage more than
normal
• 262-04 5 Volt Sensor Supply, voltage less than
normal
Expected Result:
One or more of the preceding diagnostic codes are
active.
Results:
•
Yes
Repair: Perform the following diagnostic
procedure: Troubleshooting, "5 Volt Engine
Pressure Sensor Supply Circuit - Test".
STOP.
•
No – Proceed to Test Step 2.
Test Step 2. Verify All Active Diagnostic
Codes.
A. Turn the keyswitch to the ON position. Wait at
least 15 seconds for activation of the diagnostic
codes.
B. Verify if any of the following diagnostic codes are
active:
•
100-03 Engine Oil Pressure Sensor Open
Circuit or Shorted High
•
100-04 Engine Oil Pressure Sensor Shorted
Low
•
100-10 Engine Oil Pressure Sensor Power
Supply Open Circuit
•
102-3 Intake Manifold Pressure Sensor Open
Circuit or Shorted High
•
102-4 Intake Manifold Pressure Sensor Shorted
Low
•
102-10 Intake Manifold Pressure Sensor Power
Supply Open Circuit
Note: The following diagnostic codes should not be
active:
•
262-03 5 Volt Sensor Supply, voltage more than
normal
•
262-04 5 Volt Sensor Supply, voltage less than
normal
