Summary
Some 2018-2020 F-150 vehicles equipped with a 2.7L EcoBoost engine may exhibit an illuminated malfunction indicator lamp (MIL) and/or Engine Coolant Over Temperature warning with diagnostic trouble codes (DTCs) P0116, P0117, P0118, P0119, P0128, P0217, P0330, P1026, and/or P1299. This condition may be caused by an intermittent drop in the engine coolant temperature (ECT) voltage. To correct this condition, replace the heater hose with the new relocated ECT and install a jumper harness.

Issue: Some 2018-2020 F-150 vehicles equipped with a 2.7L EcoBoost engine may exhibit an illuminated malfunction indicator lamp (MIL) and/or Engine Coolant Over Temperature warning with diagnostic trouble codes (DTCs) P0116, P0117, P0118, P0119, P0128, P0217, P0330, P1026 and/or P1299. This condition may be caused by an intermittent drop in the engine coolant temperature (ECT) voltage. To correct the condition, replace the heater hose with the new relocated ECT and install a jumper harness.
Action: Follow the Service Procedure steps to correct the condition on vehicles that meet all of the following criteria:
- 2018-2020 F-150
- 2.7L EcoBoost
- Illuminated malfunction indicator lamp (MIL) and/or Engine Coolant Over Temperature warning with DTCs P0116, P0117, P0118, P0119, P0128, P0217, P0330, P1026 and/or P1299

Service Procedure
1. Drain the cooling system. Refer to Workshop Manual (WSM), Section 303-03A.
2. Replace the heater hose with the new part containing the ECT sensor. (Figure 1)
Figure 1
3. Disconnect connector C1047 and connect the jumper harness to the connectors.
4. Secure the connectors with retainers. (Figure 2)
Figure 2
5. Route the harness under the positive crankcase ventilation (PCV) and evaporative emissions (EVAP) lines, then across the engine and connect to the ECT sensor. (Figure 3)
Figure 3
6. Clip the harness to the heater hose. (Figure 4)
Figure 4
7. Using retainers, secure the jumper harness to the engine harness in the 3 locations shown in Figure 5.
Figure 5
8. Fill the cooling system. Refer to WSM, Section 303-03A.
9. Reprogram the PCM using the latest software level of the appropriate Ford diagnostic scan tool. If the Ford diagnostic scan tool screen displays a question that includes “P552_27L_Overheat$Q”, this is an indication that the Ford diagnostic scan tool is not at the latest software level and needs to be updated to the latest software level.
NOTE: Advise the customer this vehicle is equipped with an adaptive transmission shift strategy which allows the vehicle’s computer to learn the transmission’s unique parameters and improve shift quality. When the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may result in firmer than normal upshifts and downshifts for several days.
