I recently purchased a 2000 CLK 430 with 65,000 miles on it. This is the first time I am posting a question but I can tell you I have gotten some great repair tips and I thank you all. Currently I have a question about sensors. My check engine light was on when I purchased the car and my scanner showed a PO141 and PO161 so I changed Bank 1 (sensor 2) and bank 2 (sensor 2). Check engine light went out for about 1500 miles. It popped on yesterday showing both the sensors I changes are faulty. Any suggestions?

Welcome! Please post a photo of the CLK. There is a section of the site specific to your model. If you post the question there, helpful owners will see it.

Thanks for your response Chassis. I am better with mechanical than computers so pardon the dumb questions.
I posted two photos in my album. Does that post them where you suggest they should be? Do I rewrite the thread in the CLK forum?
