Error codes

I attached the testing for the o2 sensor code. I suspect the evap codes are something obvious because you have a gross leak. More then likely a gas cap left off or leaking or you have a cracked line. Have they done any work to the vehicle recently? A lot of times this code is set when a line is left off.

Here is a guide that will help with this:

Let us know what you find. Thanks

I doubt the o2 sensor code was but I would start with one thing and clear the codes to make sure it comes back. In other words you want to fix one thing and then see if that fixes the rest. That means we need to drive it and see if the code comes back.

So you tightened the gas cap and all the same codes came back?

If so, we nee do to go through the large leak diag and find the issue. Then do the same thing of clearing the codes and retest. I suspect the leak is caused by the purge valve with those codes but we need to run through it and go from there.

Sounds great. We will wait to hear back the positive news.

Just a general question. Are you located in the USA? The reason I ask, is the EPA authorized gas stations to use winter blend fuel until it is gone. Winter blend fuel during hot weather can cause catalyst issues.

What was the actual code that you are getting now? Is it a P0420?

Okay, so that rules out that issue. However, if this code is active it is either the sensor, or 3 way converter. The fact that you only have the bank 2 code shows it is not air/fuel related. Basically it is something just on that side of the exhaust.

I would swap the o2 sensors side to side and retest. If the issue moves to the other side then you know it is a sensor issue. I attached the process for this if you need it.
