NOTE: The exhaust system must be free from any restriction to perform this
test.
Check all of the tubes and hoses between the air cleaner and the intake manifold for
loose connection, damage or restriction.
Check all of the tubes connected to the intercooler for loose connection, damage or
restriction.
Check all of the tubes and hoses connected to the turbocharger, TIP Solenoid, Surge
Solenoid and Wastegate Solenoid for loose connection, damage or restriction.
NOTE: Solenoid design and hose connections are identical for all three
solenoids. It is possible to connect the hoses to the incorrect solenoid. Verify
that hoses are connected to the correct solenoid.
Are any of these conditions evident?
All
Yes
→ Repair or replace as necessary.
Perform POWERTRAIN VERIFICATION TEST VER - 5.
No
→ Go To 4

Turn the ignition off.
Disconnect the TIP Sensor harness connector.
Disconnect the PCM harness connector.
CAUTION: DO NOT PROBE THE PCM HARNESS CONNECTORS. PROBING
THE PCM HARNESS CONNECTORS WILL DAMAGE THE PCM TERMI-
NALS RESULTING IN POOR TERMINAL TO PIN CONNECTION. INSTALL
MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (A23) TIP Signal circuit from the TIP Sensor harness
connector to the appropriate terminal of special tool #8815.
Is the resistance below 10.0 ohms?
All
Yes
→ Go To 5
No
→ Repair the open in the (A23) TIP Signal circuit.
Perform POWERTRAIN VERIFICATION TEST VER - 5.

MILLER SPECIAL TOOL #8815 TO PERFORM DIAGNOSIS.
Measure the resistance of the (K167) Sensor ground circuit from the TIP Sensor
harness connector to the appropriate terminal of special tool #8815.
Is the resistance below 10.0 ohms?
All
Yes
→ Go To 6
No
→ Repair the open in the (K167) Sensor ground circuit.
