Possible causes of this fault code include:

A damaged EGR differential pressure sensor.4903035 is the sensor part number

High resistance in the wiring harness on the signal or return wire.

Plugged or restricted EGR differential pressure sensor flow ports. Small pipe plugs must be removed from the intake connection to clean the ports.

CodesReasonEffect

Fault Code: 1866
PID(P): P411
SPN: 411
FMI: 2/2
Lamp: Amber
SRT:

Exhaust Gas Recirculation Valve Delta Pressure - Data Erratic, Intermittent, or Incorrect. An error in the EGR delta pressure signal was detected at initial key ON or the sensor failed the autozero test.

Possible reduced engine performance.

The EGR differential pressure sensor is mounted on the intake side of the engine on the air intake connection.

The sensor is connected to the engine harness through a short pigtail harness. The pigtail harness is permanently affixed to the sensor. Do not try to remove the connector that is attached to the sensor body, or damage to the sensor will result.
