Pontiac Repair: bank one sensor, pontiac grand prix, pontiac grand prix gt

Question
Could you explain how to replace the bank bank one oxygen sensor in a 2001 pontiac grand prix gt?

Answer
Hi Angie:

Bank 1 sensor is in the exhaust manifold on the back side of the engine by the fire wall. you will need a special socket to remove it from the manifold. most parts stores sell that tool you need to replace it and some parts stores have tool rentals so you don't have to buy it for a 1 time only repair. Good luck :}
