Upstream Oxygen Sensor replacement 1996 Pathy

[ardavis78]

I have a 1996 Pathy and it is coming up with a P0141(O2 Sensor B1S2 Heater Problem)...I am assuming this means a bad oxy sensor front/right side...I looked it over and there is a heat shield partially covering it...Has anyone else had to change one of these?...Do you just bend the shield back or does it require removal? Will an oxygen sensor socket work with this?....Any instructions would help greatly...Thanks...Feel free to email at ardavis78@live.com

P0141 is the passenger's side rear oxygen sensor. Replace it with http://shop.advanceautoparts.com/webapp/wcs/stores/servlet/product_premium-oxygen-sensor-bosch_18730020-p]this Bosch O2 sensor from Advance Auto Parts[/url]. You can obtain it for only $59.99 before tax if you order online using discount code RAF7JA1102 and pick-up in store.

The Driver side front is really the only pain in the rear sensor to change. You have to be super skinny to go under the brake booster or find another way. The others will just unscrew with a wrench or sensor socket.

I had a tough time with the front passenger one on mine because of a corroded heat shield that would not come off.
