I have retrieved engine code 28. i bought a bosch universal o2 sensor but i dont see where it would fit on my car. if any one could help out i would gratefully appreciate it! its driving me nuts and i cant find anything online

 

Tommy, O2 sensors are located before and after the catalytic converters, in the exhaust system.
I'm new to SC's but I imagine they are like other cars.
The above means there will be 2 on a SC300 and 4 (2 on each bank) of the SC400.
Good luck and happy hunting.

 

The reason why I was soo confused was that advance auto parts has the o2 sensors all mixed up in their computers so I had the wrong type of o2 sensor and the weird part is That thenonly 2 o2 sensors I have seen are both in the exaust manifold. When I get home ill post a picture

 

Denso # 234-1054 - Factory replacement
Denso # 234-1057 - Universal o2, same sensor all you need to do is splice into your old one with the plug

 

Yeah i returned the one the sold me and i picked up the Denso # 234-1054. Thanks to both of you replying!
