Hello guys Can anyone help me with P0133, P0156 and P0411

Ford Taurus GL 1997, Engine 3.0 EFI

I have these three codes in my car. how can i solve these problems.

P0133 - O2 Sensor Circuit Slow Response (Bank 1 Sensor 1)
P0156 - O2 Sensor Circuit Slow Response (Bank 2 Sensor 2)
P0411 - Secondary Air Injection System Incorrect Flow Detected

Thanks for your help.

Well, the air injection problem could conceivably cause the two o2 sensor codes, but I wouldn't think that's very likely. Usually the air injection pump problem is a check valve blockage, which wouldn't cause a slow o2 response. However, if the check valve was damaged, allow air injection with no restriction, it could be the cause.
If the codes all came at once, suspect the airpump, however unlikely.
If the o2 codes have been there for some time, check and replace o2s as necessary.(check for any holes in exhaust system first, making sure it is intact)

thanks for your answer.

i check exhaust system and it is intact

mi car have four o2 sensor, can you tell me where are located these parts:

o2 bank 1 sensor 1
o2 bank 2 sensor 2
Secondary Air Injection System

get a service manual or a http://www.alldata subscription. If you don't know where an 02 sensor is located and you don't seem to have a clue what a secondary air injection system is you're probably already in over your head!

Bank 1 sensor 1 is the front sensor on the side of the engine with #1 cylinder. Bank 2, 2 is the rear(post catalytic converter sensor) on the side of the engine with cylinder 2.
The secondary air pump is a pump driven by the serpentine belt and will have air hoses going from it.

thanks for your help

no prob
