Codes P0128, P0171, P0324, P2076, Trac light on and idles rough

Hi,

The codes you provided are all over the place. One is for a knock sensor, one is a coolant temperature sensor, one is the intake manifold runner, and one is a lean fuel mixture.

By chance, do you have access to a live data scan tool? If you do, could you let me know what the short-term fuel trims are?

Next, if you have a basic scan tool, clear the codes, and see which one comes back first. Also, I need you to pay attention to the temperature gauge to make sure it is working properly, and I need you to check for engine vacuum leaks.

Here is a link that explains how to check for vacuum leaks:

Let me know.

Hi,

The P0700 is a game-changer. I still want you to check for the leaks, but a P0700 is a generic code indicating the transmission control module has requested the powertrain control module to turn on. That sounds confusing, but what it means is there is a diagnostic trouble code stored in the transmission control module. We need to see what that is. It requires a scan tool that can read can-bus codes.

CAN stands for controller area network. Basically, all the different computers/modules are tied together via a few wires so they can communicate back and forth. This is what is required to retrieve all codes. Here is a link showing how it's done:

After looking at all the codes you have and how they are all different circuits, I'm starting to question if the powertrain control module is failing. These many different things don't all happen at the same time. Well, I guess it's possible but extremely unlikely.

Let me know. Also, the two codes (P0717 and P2076) can be related. One is a runner control which is part of the intake, and the other is a lean fuel mixture. So, it is important to check for vacuum leaks.

Let me know what is found.

Great. Repair the leak, clear the codes, and see what returns (if anything).

Let me know what you find or if I can help. This leak explains at least part of the codes.

Take care,

Joe
