  • 1.6L OR 2.0L GTDI - DRIVABILITY CONCERNS WITH DTCS P0106/P0236/P06A7 - OR ENGINE FAULT SERVICE ENGINE NOW MESSAGE WITHOUT DTCS
Publication Date: July 11, 2013

FORD:
2013 Escape

ISSUE:

Some 2013 Escape vehicles equipped with 1.6L or 2.0L Gasoline Turbocharged Direct Injection (GTDI) engines may exhibit difficult to start, runs rough at start up, crank no start, lack of power, loss of RPM or hesitation concerns with diagnostic trouble codes (DTCs) P0106, P0236, or P06A7. These conditions may be caused by corrosion in connector terminals of the Turbocharger Boost Sensor/Charge Air Cooler Sensor (TCBP/CACT/MAPT), or a wiring concern in signal return splices for TCBP/CACT/MAPT and MAP sensors. Some vehicles may also exhibit a drivability concern along with an Engine Fault Service Engine Now message in the Instrument Panel Cluster (IPC) message center, without any DTCs in self test.

ACTION:

Follow the Service Procedure Steps to correct the condition.

SERVICE PROCEDURE

  1. Using Integrated Diagnostic System (IDS), check for DTCs.
  2. Does the vehicle exhibit a drivability concern with DTC P06A7 stored?
    1. Yes - replace TCBP/CACT/MAPT sensor and connector pigtail. Refer to Workshop Manual (WSM), section 303-14, and Wiring Diagram, Section 5-1. (Figures 1 and 2)
      1. Other DTCs may be present along with P06A7, which share the VREF circuit.
      2. 1.6L GTDI engine TCBP/CACT (MAPT) sensor location. (Figure 1)


        Figure 1 - Article 13-7-5

      3. 2.0L GTDI engine TCBP/CACT (MAPT) sensor location. (Figure 2)


        Figure 2 - Article 13-7-5

    2. No - proceed to Step 3.
  3. Does the vehicle exhibit a drivability concern with only DTC P0106 or P0236 stored?
    1. Yes - replace the signal return splice for MAP sensor (DTC P0106) or for TCBP/CACT/MAPT sensor DTC P0236. Refer to Workshop Manual (WSM), section 303-14, and Wiring Diagram, Section 5-1. (Figures 3-5).
      1. 1.6L GTDI engine MAP sensor signal return splice location (S123). (Figure 3)


        Figure 3 - Article 13-7-5

      2. 1.6L GTDI engine TCBP/CACT signal return splice location (S178). (Figure 4)


        Figure 4 - Article 13-7-5

      3. 2.0L GTDI engine MAP (S108) and TCBP/CACT (S182) signal return splice locations. (Figure 5)


        Figure 5 - Article 13-7-5

    2. No - proceed to Step 4.
  4. If the vehicle exhibits a drivability concern along with an Engine Fault Service Engine Now message in the Instrument Panel Cluster (IPC) message center without any DTCs stored in PCM memory, perform wiggle test on Powertrain Control Module engine harness (12A581) while monitoring MAP, TCBP and BARO Sensors PSI with IDS. If signal noise or VREF pull down is confirmed during harness wiggle test, replace the Signal Return splice for MAP or TCBP/CACT/MAPT sensors. Refer to Workshop Manual (WSM), section 303-14, and Wiring Diagram, Section 5-1. (Figures 3-7)
    1. Some of the splices have more than just MAP or TCBP/CACT signal return circuits; replace all signal return circuits in these splices.
    2. 1.6L or 2.0L GTDI engine wiggle test here by pushing and pulling on the harness lightly while monitoring MAP, BARO, TIP_PRS-BOOST at key on engine off (KOEO). (Figure 6)


      Figure 6 - Article 13-7-5

    3. 2.0L GTDI engine wiggle test here by pushing and pulling on the harness lightly while monitoring MAP, BARO, TIP_PRS-BOOST pressure in PSI units at KOEO. (Figure 7)
