Some 2012 Explorer vehicles built on or before 10/1/2011 and equipped with a 2.0L Gasoline Turbocharged Direct Injection (GTDI) engine may exhibit an illuminated MIL with DTC P144C. This may be due to a blocked vapor purge line port in the air cleaner outlet pipe assembly.
ACTION:
Follow the Service Procedure steps to correct the condition.
SERVICE PROCEDURE
- Disconnect battery ground cable. Refer to Workshop Manual (WSM), Section 414-01.
- Disconnect evaporative emission fuel vapor tube quick connect coupling from the air intake duct center section. Refer to WSM, Section 303-13. (Figure 1)
Figure 1 – Article 13-5-29 - Insert a 5.0 mm (.197″) drill bit or equivalent diameter gauge into the vapor purge line port on the air intake duct center section to determine if it is blocked by plastic flashing. A 5.0 mm (.197″) minimum opening is required for proper Evaporative Emission system operation during boost.
- Does drill bit or equivalent diameter gauge pass through vapor purge line port?
