I just went for inspection and failed once again due to OBD Codes : P0150 and P0325

Can anyone give me some advice on what these problems are, what it takes to fix them, and how much it should ideally cost.

Thanks

 

Did you read the stickies?

Code: P0150 | Description: Closed Loop Control

Code: P0150 | Description: O2 sensor fault


Code: P0325 | Description: Knock Sensor


Did you search those error codes? Do any diagnostics yet?

 

1-Your knock sensor is gone
2-Your oxygen sensor is gone (the most front one,left front bank)

costs depend on how do you manage the case
Steelers----------> may be 300-400 $$ bill !! (labor only)
youself -----------> costs of new oxygen sensor +knock sensor + 2 to 3 hours+right tools and approach

 

P0325 - my favorite code
buy the parts and change them yourself. not very hard and you can find instructions on here
