TSB 13-9-7 (wiring harness)

FORD: 2013-2014 Focus

Some 2013-2014 Focus ST vehicles may exhibit difficult to start, runs rough, crank-no start, lack of power, loss of idle RPM or hesitation concerns with DTC P0106 and/or P0236. These conditions may be caused by a wiring concern in signal return splices.


Follow the Service Procedure Steps to correct the condition.


Using Integrated Diagnostic System (IDS), check for DTCs.
Does the vehicle exhibit a drivability concern with DTC P0106 or P0236?
Yes – proceed to Step 3.
No – this article does not apply. Refer to the Powertrain Control/Emissions Diagnosis (PC/ED) Manual for normal diagnosis.

Replace signal return splice with 0.75 mm (18 AWG) wire using the crimp method. Affected splice numbers are S132 and S133. Refer to Wiring Diagram, Section 5-1.
Remove the engine appearance cover.
Remove the air cleaner tube from the housing.
Disconnect the tube for the engine sound symposer at the intake manifold.
Position and secure the upper radiator hose aside using mechanics wire or equivalent.
To increase access to the wire harness release the support clip from harness to coolant inlet valve hose.
Remove enough harness wrap to locate and replace splices.
Backfill the crimp with solder before sealing repair with heat shrink tube.
After wire repair, reverse the removal procedure.

The car is still a work in progress. My next agenda is aesthetics It is currently my daily driver, so some of the mods are dialed towards the everyday driver aspect. I partake in autocross on the weekends, though Capital Driving Club (see our events page for a list of their events).
