Keep the test area well ventilated. Failure to do so may result in possible serious or fatal injury. Turn the ignition off. To continue testing, you will need Evaporative Emission Leak Detector (EELD) (special tool #8404C, Kit, EELD And Accessory). 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 EELD to the battery positive terminal and the black ground lead to battery negative terminal. Block the vent hose of the Evap Canister. 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 0.040 orifice on the tester's control panel. Press the remote smoke/air start button. Position the red flag on the air flow meter so it is aligned with the indicator ball. When the calibration is complete, release the remote button. The EELD flow meter is now calibrated in liters per minute. Install the service port adapter (special tool #8404-14, Adapter, Evaporative Service Port) on the vehicle's service port (if equipped) or install the service adapter (special tool #8404-ADP, Smoke Machine Adapters) into the filter line. Connect the AIR supply hose from the EELD to the service port (if equipped) or to the adapter (special tool #8404-ADP, Smoke Machine Adapters). Press the remote button to activate AIR flow. NOTE: Larger volume fuel tanks, lower fuel levels, or vehicles equipped with a Flow Management Valve may indicate high flow and will require four to five minutes to fill.

Yes Go To 10 No Go To 12
10. EVAPORATIVE EMISSION LEAK DETECTION NOTE: A thorough visual inspection of the EVAP system hoses, tubes, and connections may save time in your diagnosis. Look for any physical damage or signs of wetness at connections. The strong smell of fuel vapors may aid diagnosis also. Remove the Air supply hose from the service port or the adapter (special tool #8404-ADP, Smoke Machine Adapters). Connect the SMOKE supply tip (black hose) to the service port (if equipped) or to the adapter (special tool #8404-ADP, Smoke Machine Adapters). Set the smoke/air control switch to SMOKE. NOTE: The flow meter indicator ball will not move at this point. Press the remote smoke/air start button. NOTE: Make sure that smoke has filled the EVAP System by continuing to press the remote smoke/air start button, remove the vehicle fuel cap, and wait for the smoke to exit. Once smoke is indicated reinstall the fuel cap. NOTE: For optimal performance, introduce smoke into the system for an additional 60 seconds; continue introducing smoke at 15 second intervals, as necessary. While still holding the remote smoke/air start button, use the white light (special tool #8404-CLL, Light, White) to follow the EVAP system path, and look for the source of the leak indicated by exiting smoke. If a leak is concealed from view (i.e., top of fuel tank), release the remote smoke/air start button, and use the ultraviolet (UV) black light (special tool #8404-UVL, Light, UV) and the yellow goggles (special tool #8404-20, Goggles, Yellow) to look for residual traces of dye that are left behind by the smoke. The exiting smoke deposits a residual fluid that is either bright green or bright yellow in color when viewed with a UV light. NOTE: The EVAP system is divided into three zones. A leak from any of these zones can cause this DTC to set. The lists below specify the possible leak points in that specific zone. For further assistance see the Zone Identification Charts below.

After the Evaporative System small leak test has passed, with the engine running, ambient temperature between 4°C (40°F) and 35°C (95°F), with the engine at idle after a calibrated amount of drive time has accumulated.

If the Powertrain Control Module (PCM) detects that the purge vapor ratio and the ESIM switch closed ratio are below a calculated value, the PCM commands the purge solenoid to flow at a specified rate to update the purge vapor ratio. If the ratio remains below a specified value, a one trip failure is recorded. Two Trip Fault. Three good trips to turn off the MIL.

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. Refer to PRE-DIAGNOSTIC TROUBLESHOOTING PROCEDURE .

With the engine run time above a calibrated value, battery voltage greater than 10.4 Volts, ECT within a specific range, and the Evap Purge Solenoid control active.

This PCM compares the circuit feedback to a calibrated closed range when the circuit is de-energized or to a calibrated open range when the circuit is energized. If the value is determined to be out of the calibrated range in either the de-energized or energized state for more than a calibrated amount of time, this DTC will set.
