Troubleshooting Test Steps
Values Results
4. Check the Suspect Pressure Sensor
A. Turn the keyswitch to the OFF position.
B. Disconnect the connector for the suspect sensor and re-
move the sensor from the engine.
C. Check the sensor for a blockage.
D. Temporarily reconnect the sensor to the harness. Do not in-
stall the sensor on the engine.
E. Turn the keyswitch to the ON position. Do not start the
engine.
F. Check for an active -13 diagnostic code for the suspect
sensor.
Barometric pressure
sensor fault
Result: There is an active -13 code or the sensor is
blocked
Temporarily connect a new sensor to the harness. Use
the electronic service tool to confirm that the repair elimi-
nates the fault.
If the fault is eliminated, permanently install the new sen-
sor. Refer to Disassembly & Assembly for the correct in-
stallation procedure.
If the fault is still present, proceed to Test Step 3.
Result: There is no active -13 code.
Check that the sensor pipe is free of blockages or re-
strictions. Refer to Illustration 129 . If necessary, remove
the pipe and clear any blockage with an air line that is
set at a maximum pressure of 200 kPa (29 psi). If the
blockage is cleared, reinstall the pipe. If the blockage
cannot be cleared or there is a restriction, replace the
pipe.
Install the sensor. Refer to Disassembly & Assembly for
the correct installation procedure.
Turn the keyswitch to the ON position. Run the engine at
idle speed for 5 minutes.
Turn the keyswitch to the OFF position. Ensure ECM is
fully powered-down.
Turn the keyswitch to the ON position. Do not start the
engine. Wait for 10 seconds. Confirm code is not active.
Use the electronic service tool to clear all logged codes.
If the fault is still present, contact the Dealer Solutions
Network (DSN).
