*INTAKE AIR SYSTEM PRESSURE TEST
Diagnostic Test
1.CHARGE AIR COOLER PRESSURE TEST
Loosen air inlet tube clamp at the turbocharger.
Remove the air filter housing and the inlet tube from the vehicle as an assembly.
Install the CAC Pressure Tester #9022 into the inner diameter of the turbocharger, securing it in place with the
supplied three-fingered band clamp, tighten tool clamp to 8n.m (72 in lbs).
NOTE: NEVER ATTEMPT TO START OR RUN THE VEHICLE AT ANY TIME DURING THIS TEST,ENGINE DAM-
AGE MAY OCCUR.
Fasten the safety chain around a solid surface behind the turbocharger. Warning: Never run CAC Pressure test
without the safety chain securely fastened.
Before attaching shop air to the pressure regulator verify that the regulator is at its lowest pressure setting (0 psi).
Attach an air supply to the regulator and slowly increase the pressure until the pressure gauge reads 20 psi.
WARNING: WARNING: Never apply more than 20 PSI.
Using a solution of soap and water spray the Turbocharger, Turbocharger wastegate, Charge Air Cooler Heat
Exchange and CAC Hoses while watching for leaks.
Before any attempt to repair the CAC system is made, its necessary to completely discharge the system. This can
be accomplished by turning the regulator knob counter-clockwise.
Allow for adequate time to pass before removing the CAC Pressure tester from the turbo charger inlet.
Position the Air Filter Housing over thethreemountingstudslocatedonthe inside front fender well and press down
firmly to lock housing into place.
Install Air Inlet Tube over the Turbocharger inlet and torque the band clampto35in.lbs.

3.VISUAL AND PHYSICAL INSPECTION
Perform a visual and physical inspection of the entire Evaporative Emission system.
Check for the follow conditions:
- Holes or cracks
- Loose seal points
- Evidence of damaged components
- Incorrect routing of hoses and tubes
- Fuel Cap gasket seal
Were any of the above conditions found?
Ye s>>
Repair as necessary.
Perform the POWERTRAIN VERIFICATION TEST. (Refer to 9 - ENGINE - STANDARD PROCEDURE)
No>>

4.VERIFY EVAPORATIVE EMISSION LEAK
To continue testing you will need Miller Tool #8404A Evaporative EmissionLeak Detector (EELD).
WARNING: Keep lit cigarettes, sparks, flames, and other ignition sourcesaway from the test area to prevent
the ignition of explosive gases. Keep the test area well ventilated.
NOTE: The fuel tank should have between 20% and 80% of fuel tank capacity to properly test the Evap
system.
Connect the red power lead of the EELD to the battery positive terminal and the black ground lead to battery neg-
ative terminal.
Block the vent hose of the canister if using the service port.
Connect shop air to the EELD.
Set the smoke/air control switch to AIR.
Insert the tester’s AIR supply tip (clear hose) into the appropriate calibration orifice on the tester’s control panel
(based on DTC leak size).
Press the remote smoke/air start button.
Position the red flag on the air flow meter so it is aligned with the indicatorball.
When the calibration is complete, release the remote button. The EELD flowmeter is now calibrated in liters per
minute to the size leak indicated by the DTC set in the PCM.
Install the service port adapter #8404-14 on the vehicle’s service port and block the vent hose of the EVAP Canister
(if equipped) or install the #8404-ADP service adaptor into the filter line.
Connect the Air supply hose from the EELD to the service port (if equipped) or to the #8404-ADP adapter.
Press the remote button to activate AIR flow.
NOTE: Larger volume fuel tanks, lower fuel levels or if the vehicle is equipped with a Flow Management
Valve may indicate high flow and will require 4 to 5 minutes to fill.
Compare the flow meter indicator ball reading to the red flag.
ABOVE the red flag indicates a leak present.
BELOW the red flag indicates a sealed system.
Is the indicator ball above the red flag?
Ye s>>
Go To 5
No>>
Refer to the Freeze Frame data recorded in Step 1. If the data indicates thatthe vehicle was in motion
when the DTC was set, verify that all hoses are properly connected. Test Complete.
