Throwing some trouble codes

[2000Z28]

DTC P0161 and DTC P1416?
anybody know what these mean or if i should be worried about them???

P0161 Heated Oxygen Sensor (HO2S) heater circuit Bank 2 Sensor 2
This one usually means the heater went out on the O2 sensor. I would replace both if you have the cash.

P1416 Secondary Air Injection (AIR) system Bank 2
Check the check valve on the manifold. It could be clogged or your air pump could be going out.

I think they are like 60 bucks a peace for the bosch....and like 75 a peace for the AC delcos.

[Tony]

Yes. Don't get Bosch.

how do i look up what these codes on my own and know what they mean...just for the future?

[Tony]

The easiest (and cheapest) way is to just take it to Autozone. They do it for free. But, you can drop $40 and get a scanner for your car. I have one and I love it.

so does the scanner just tell you what the problem is and what you need? and where can i get one of these scanners?

[Tony]

The cheap ones will tell you what the code is and you will have to look it up in the book they give you. You can get them at Autozone as well.

i have something to read the codes but i need the book that tells me what they mean lol

If you just need to know what all the codes mean, then just go Here. On the bottome of the page, you can switch from obd1 to obd2 and trans codes.
