U0600 Lost Communication With Engine Oil Pressure Sensor A

Newer engines often use a digital oil pressure sensor that sends its value over a SENT line (SAE J2716) instead of an analog voltage. SENT is a one-way link with a 5 V supply, a signal wire and ground; each frame carries a CRC and a status nibble. U0600 means the engine controller no longer receives valid frames from oil pressure sensor A. Ford's gasoline summaries for 2020 to 2023 and 2024 list it with P0520 under the SENT oil pressure check: continuous, battery above 11 V, 5 s to register. Ford's 2023 diesel summary uses it when the SENT sensor reports a communication error. CARB 1968.2 requires a separate code for lost communication on computer-coded inputs. Oil pressure control and the low-pressure warning lose their input.

Likely causes

Open, shorted or chafed SENT signal, supply or ground wire
Oil pressure sensor electronics failed
Oil or corrosion in the sensor connector

Symptoms

  • Check engine light on
  • Oil pressure warning or no oil pressure reading
