Not sure, my book only covers the LSJ. Im sure the wording for the code is the same since its OBDII but the corrective action is proabably didffrent.

P0140 - 02 Sensor Circuit No Activity Detected (Bank 1 Sensor 2)

This would happen if your o2 sensor was not connected.

Check the wire on the exhaust after the cat con, you will need to get under your car, see if the o2 sensor wire is not disconnected from the sensor, it could be as simple as a unplugged sensor.
