All cars sold in the US after 1995 use the same on board diagnotics called OBD-II. The codes are the same. Search OBM-II error codes and you'll get a listing.
P1150 Air/Fuel Sensor Circuit Range/Performance. (cylinder bank 1 Sensor 2)
P1150 may mean that one or more of the following has happened:
water or corrosion in the O2 sensor connector, loose terminals in the connector, wiring burnt on exhaust components, open or short in the wiring due to rubbing on engine components, holes in exhaust allowing unmetered oxygen into exhaust system, unmetered vacuum leak at the engine, bad O2 sensor or bad PCM.
P1155 Air/Fuel Sensor Heater Circuit. (cylinder bank 1 Sensor 2)
P1155 may mean that one or more of the following has happened: O2 Heater element resistance is high, Internal short or open in the heater element or O2 heater circuit wiring high resistance
Solution :Replace oxygen sensor and see if the problem goes away.

SOURCE: check engine sign appeared on
Appears it is an Oxygen sensor error, they are located in the exhaust system, in the v6, that code indicates the second bank (but unsure which bank that is) Ideally you need to take the car in for service, or at least inspect the Oxygen sensors, the code indicates that teh heater element has failed.
