Land Rover Sensor Is Mismatched
This bulletin applies to 2014 and later Land Rover Defender, Discovery, Evoque, Sport and Velar vehicles. The AJ20 D4 engine harness may have a mismatch with the exhaust gas pressure sensor LR127945.
The supplier of the exhaust gas pressure sensor discontinued the sensor that originally matched the sensor harness. The new sensor has a different connector and pin layout which will not connect to the original sensor harness. If the sensor is replaced with the new version, the sensor harness must be changed to P/N LR138602.
