To all you savvy DIY Toyota Lexus Tech's please give me a PM or leave a comment

 

Check your battery first. You can have it tested at your local auto parts. How old is your battery? The 2IS will throw some wierd codes when having battery, or alternator issues.

This morning's look underneath the hood
okay I check the voltage system on my diagnostic screen and I was getting 15.6 of 15.7 as you can see I highlighted something in particular from the link you sent me what are your thoughts
New battery about a good two months of use had to recharge it last week because I left my trunk light on for several days when I changed out my lower ball joint inner outer tie rods. Afamily mechanic changed out my alternator Last Summer.

upon the end of my search underneath the hood I ran into this craziest thing and couldn't believe my eyes here take a look Right there in the highlighted area there is a small pocket that's difficult to get to but look what I found I couldn't believe my eyes

If that wiring gets fixed and reconnected what my code errors be fixed I'm very surprised to find that

I also found this underneath the driver's wheel

The black connector is that supposed to be connected to something

 

I think your voltage should be around 13.8. Those numbers seem high to me. I can't see your photos really good on mobile. It looks like something chewed the wiring?

 

Those voltages would cook a battery. My first thought was that if the battery is open internally, the voltage will soar as the alternator has no load.

So you have some chewed and burned wires. Not good. You'll a shop manual and determine which connectors those are and what they do.

Some history? You buy it this way?
