Here are the codes any info would help

I would start with checking the battery and alternator. That many codes almost always starts with electrical issues.

I check the battery and it has 12.4 volts and the alternator has 14.3 volts I don't know if the connectors on the alternator and corroded I will have to check in the morning

Check grounds as well. I would also check to make sure you don't have sunroof drains leaking on to the electricals under the dash. 90% of issues I have round in Rovers is due to power issues.

So I know there was a leak under the passenger side dash but there hasnt been a leak in a While the grounds look fine and I didnt see any corrosion I have been looking around and would a hard reset work also I noticed it will unlock and lock about twice before dying or the low batter light comes on

 

[joey]

I know corrosion can get into the wiring harness on the passenger side footwell that will cause some very fun electrical issues. A hard reset isn't going to correct it if it is corrosion or a bad connection.

That’s quite a variety of codes - transmission, engine temp, alternator - all over the place. Can you see from your scanner when the codes were set?

You might start by taking a screen shot/picture of the codes for your records, then clearing all the codes and driving around some. See what codes come back. If you haven’t scanned for codes in a while, some of those codes might be old and no longer active.

Once you see what codes are returning, you’ll hopefully have a better idea of how to locate the problem.

Also, what kind of symptoms are you having that has caused you to look for codes in the first place?

So I was able to clear the code and replaced the brake light switch and had that cleared about 9 codes but her is what came back I did checkt he passenger side fuse box because I was told it did leak but has not for a while no I do have after market wheels with no tpms Ithem idk if that could be causing it but idk I'm lost on this one

A bunch of the codes are definitely the TPMS. Other codes are not, but they seem to all be ”U” codes (communication codes). If you are not having any issues, like the instrument panel blanking out, or the radio not working, etc., you can probably just let it be for a while. I’d clear them, drive for a while, check it again in a week, maybe clear them again (assuming your not having any issues). See if they correct themselves or if any symptoms or new codes show up.

Yea I'm was going to do that I found out 4bulbs where wrong and one headlight Ignitor had corrosion. But thereis these two code that keep coming back do u think that the fuel temperature gauge has anything to do with the coolant sensor I do know there is a coolant leak I did have the water pump replaced about a year ago idk if u are fimillur with any other issues idk if the thermostat housing leaks
