DTC P0238 Set After Sensors Disconnected During Repairs

Some 2019 XT4 models equipped with the 2.0L 4-cylinder engine (RPO LSY) may have DTC P0238 (Turbocharger Boost Sensor Circuit High Voltage) set after service repairs were performed that required the Air Conditioning Refrigerant Pressure Sensor and Turbocharger Air Pressure Sensor to be disconnected.

The B1 Air Conditioning Refrigerant Pressure Sensor (Fig. 13) and B111 Turbocharger Air Pressure Sensor (Boost Sensor) (Fig. 14) are in close proximity to one another behind the front fascia and it’s possible that, with some force, the two sensor connectors could be accidentally crossed during service repairs.

Refer to the wiring schematics and connector end views in the appropriate Service Information to ensure the sensor connectors are not swapped with each other.
