Diagnostic test codes show more short to ground errors, can most of these code be related to it?

Hi and thanks for using 2CarPros.com.

I looked through as many of the picture that would open. For some reason I cannot open four of them. The two that I saw both indicate an open circuit. Based on that, yes a bad ground can cause the issue because the circuit is not closed via the ground.

Here are basic directions for using a test light and checking wiring. I am adding this in case you want to check things yourself.

If you could, let me know what symptoms you are experiencing.

Thanks,
Joe

Good day Joe. Thanks for getting back to me. I am very new to the car things. I really do not know where to start. Every mechanic tells me a different thing that is why I joined you guys. I will try and resend you the faults.

Hi again. I am so sorry. I have replied three times and it will not send things to you. I am doing this as a test before I do it a fourth time. I have a ton of information for you and cannot get it to you.

Testing again:

Joe

Why can you not just send it here. Your messages are getting through to me so clearly you can send it here but it is cool if you cannot. Thanks anyway.

I have the site owner checking into it. Every time I attach the pictures and all the directions, it does not send. Honestly, I have tried five times. It takes about forty minutes each time I do it. I will get in touch with the owner again. This is the only link that it is doing it. I have an idea, repost your question and ask that only I answer it so nobody else jumps in. Maybe with a new post, it will work. Again, I am sorry for the problems.

If you repost it, let me know and I will watch for it.

Yes, we are having issues and trying to work it out. Joe please send me the images and I will upload them for you.

I would clear all codes and then just turn the key to the on position without starting the engine to see the hard codes. It looks like the PCM is having an issue. Has the car had any water damage?

The first group of pictures I sent are general and indicate grounding locations. I attached them if you want to check. The next pictures I sent correlate with the following directions. One of the codes you have deals with the throttle pedal position sensor. I need you to try this test and let me know what you find. That way I can determine if there is a voltage problem or the switch itself is bad.

Good day. I finally got your pictures. I will print them and try an follow these steps. I think the battery I had might be weak. I need to upgrade to a 652 battery cause the voltage is very low. The car keep switching off. Meaning I have to jump start it all the time. I did a test on the alternator the alternator seem to work. I am very new to cars so I will have to ask someone to assist me with the ground test as you explained.
