This article supersedes TSB 12-10-19 to update the Issue Statement and Service Procedure.

ISSUE:

Some 2011-2012 F-150 equipped with a 3.5L gasoline turbocharged direct injection (GTDI) Ecoboost engine may exhibit an intermittent stumble and/or misfire on hard acceleration after an extended drive at highway speeds during high humid or damp conditions. This may result in either a steady or flashing malfunction indicator lamp (MIL). Diagnostic trouble codes (DTC s) P0304, P0305, P0306, or P0430 may also be present. Evidence of misfire may be available in Misfire Freeze Frame Data even with no active DTC's.

ACTION:

Follow the Service Procedure steps to correct the condition.

SERVICE PROCEDURE

  1. Acquire Misfire Freeze Frame Data and DTC’s with the IDS. Use the following steps with IDS to obtain Misfire Freeze Frame Data.
    1. Select Toolbox
    2. Then Data Logger
    3. Then Modules
    4. Then PCM
    5. Next select the following PIDS: MFF_LOAD and MFF_RPM
  2. Check for DTC P0430. Is DTC P0430 present?
    1. Yes - replace the left bank catalytic converter assembly. Refer to Workshop Manual (WSM), Section 309-00. Proceed to Step 3.
    2. No - Proceed to Step 3.
  3. Is the misfire concern only repeatable in humid or damp conditions?

    2. No - this article does not apply. Refer to Powertrain Control Emission Diagnosis (PC/ED) Manual Section 3: Powertrain Symptom Index to inspect such areas as Ignition, Compression, and Injection.
  4. Does the Misfire Freeze Frame Data indicate engine speed above 2500 RPM and load 100% or above? (Figure 1)


    Figure 1 - Article 13-3-3

    1. Yes - proceed to Step 5.
    2. No - this article does not apply. Refer to PC/ED Manual Section 3: Powertrain Symptom Index to inspect such areas as Ignition, Compression, and Injection.
