Exclamation codes P1055 and p1647
we first got code p1647, so we replaced both O2 Sensors, now we keep getting code p1055...we checked the wires, we checked for vaccuum leaks and everything seems OK...any idea what the problem could be....maybe we need a new ECM ???

Jag doesn't use P1055.

If it is P0155, then it is a problem with the O2 heater circuit Bank 2, Sensor 1. As you look at the engine from the front of the car , Bank 2 is on your right. Sensor 1 is the first O2 sensor.

We need more info please.
