Some Wiring Required

Some 2012-2014 Ford Explorer vehicles equipped with a 2.0L GTDI (gasoline turbocharged direct injection) engine may exhibit a difficult-to-start, rough running, crank-no-start, lack of power, loss of idle rpm or hesitation concerns, along with DTCs P0106, P0236 or a repeat P0128. These conditions may be caused by a wiring concern in the signal return splice.

1. Using IDS (integrated diagnostic system), check for DTCs.

2. Does the vehicle have only P0128 stored? If no, proceed to Step 4. If yes, proceed to Step 3.

3. Is the coolant level full? If no, fill the cooling system using the vacuum cooling system filler procedure (refer to the workshop manual), then proceed to Step 4. If coolant is already full, proceed to Step 4.

4. Replace the signal return splice with 0.75 mm (18 AWG) wire using the crimp method. Backfill the crimp with solder before sealing the repair with heat shrink tubing. Ford suggests using terminal kit P/N 3U2Z-14A088-BA.
