Having problems with your 1997 Pontiac Grand Am ?

Code P0141. O2 Sensor heater circuit fault (Bank1, Sensor 2). Is this a bad O2 sensor at the CAT?

Answers :

It is probably the sensor before the cat. if it has a heater. The heater circuit going bad is a common problem, it does not affect the way the car runs after it warms up, it is an emission device to heat the O2 sensor up quicker than the hot exhaust gas would. It should be replaced because it will keep your check engine light on and you would not be able to pass an emission test.
Ive replaced my crank shaft position sensor, changed out all my spark plugs and my car still boggs down some. It wont start in the mornings either but it usually kicks on in the evenings. Please help
