i found out a while back that my o2 sensor near my cat needs to be replaced. do you know what bank that is? 1 or 2? because i need to pick the part up tommorow. I also got a ode for my EGR valve, do you think the o2 sensor had anyhting to do with it?

Thanks
john

 

Bank 1 is near the firewall and bank 2 is near the radiator. Sensor 1 is closest to the manifold and sensor 2 is closest to the cat.

 

What code did you get for the O2 sensor, and what code did you get for the EGR system?

We can't help you with the codes.
