blytha replied to blytha's topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Hi, I've checked with the retailer and it's the correct sensor. I've also monitored the voltages on the sensor, (well a friend did :wrench: ) and the sensor is definitely failing. Looks as though I will need to get the pre cat sensor as well :cursing: . Thanks for all the help
blytha posted a topic in 996 Series (Carrera, Carrera 4, Carrera 4S, Targa)Just a quick question. I've replaced my post cat Lambda sensor with one of these, due to a P0160 code (bank 2 post cat issue), now the car is giving P0050 and P0154 errors (bank 2 pre cat issue). I’m in a quandary now, as I have just gone on there to check for a Pre cat O2 sensor and noticed that the date for the part I fitted was 09/01 – 07/04 and was wondering whether the part I fitted was wrong? No errors on post cat sensor! My car is a 2005 C4S with and M96.03 engine. Also is it usual for one sensor to be replaced just for one that is not replaced to throw an error Any help appreciated.
