2002 Don't know who to trust

I got the fluid changed yesterday. He said the 2 codes went away but there was another subcode having to do with fuel/air ratio. I did not remember at the time to get the number from him. Probably won't be able to dig into that more until I get my own scanner. Would that be because I topped it off twice before I knew not to, or is it unrelated?

When he looked at it the first time, the check engine light went off because he probably reset the codes. It didn't come back until this morning, which really freaked me out. All of the other lights have stayed on throughout this whole process.

 

Were you able to find a correlation of module voltages and degree of corrosion? I've long suspected that corrosion, the evidence of KOH leakage, should eventually cause a mismatch of module voltages.

I very much appreciate the photos and somehow had not noticed the 'pot metal' on the buss bar plastic housing. So I had been thinking the resistance path was from the terminals to the base. But now I'm starting to think the pot-metal liner around the buss bar plastic might pay a larger role. A funny thing about photos, they often reveal details not found in an initial inspection, thanks!

The mechanic who looked at my battery said there was corrosion, but said he could not see any leakage/corrosion. Is leakage just worse corrosion or where the fluid has actually "exploded" from the cell?

 

Hello. First of all, I want to just thank everyone so much for their generous input and attention to questions I have had over time. It has really meant so much to me and calmed my nerves to know I am not alone.

An update:
I did have the ATF fluid exchange as mentioned. The warning lights are still on in my car. However, I have decided not to take any more action at this time since the car is running well. I will modify my approach as needed.

Take care!

 

Thank you again!

 

Sure, thanks again for all of your help!! Surely I will recruit your wisdom again.

 

Avi, I need your help. I feel like a complete whackadoo with this one, since it is surely past accident related. Those always make me feel like an idiot. But I really need to fix it, low cost, since it is just plain annoying.
My car is leaking!!!
I thought it was a bad seal on the rear windshield. Someone who works for a collision-glass company inspected it and told me it wasn't. He ran a hose on the roof and told me it was the sunroof. I closed it as best as I could and propped it up on the low corner. Today there was a really hard rain, as there usually is at least once a day in FL summertime, and the seeping happened again. That which I used to prop up that corner was not saturated! Do you think it is just in general the whole weather seal needing to replaced since it is old? Can I just do that myself?
Location of the internal leak: right above the rear-passenger window, to the bottom right of the handle right there. It seems that water pools right inside the headliner, which causes it to drop down onto the back seat a bit as well as run along the panel between the seat and the door for a nice puddle on the rear passenger floor. Also, there are some little pokey things right inside the headliner there. Do you think one of the sunroof drains is possibly plugged or that there could be a hole rusted out in there due to lack of attention on the matter before I owned it?
Thank you soooo much.

 

Yes I know. The sunroof was put in aftermarket in '02, per a sticker in my glovebox. Plus, I have no desire to overpay for the repair. That's why I'm hoping I can replace the weather stripping myself and prop it up. After all, mechanical takes priority!! And we all know where I'm at on that.
I just need to foster it to prevent leaking at this point. There is a lot of water coming in.

 

Will do, tomorrow. I figured that might be helpful.

 

All is true in my case. Toyota has already said they don't want to mess with it.

 

Thank you for the ideas. I spoke with the company today who installed it 10 years ago. They sent me to a website that has service techs and installers they recommend. Since they were closed when I got off work, I have to try them tomorrow morning. He said if the sunroof has never been serviced, and I'm assuming it hasn't, that it probably is leaking and described what is visibly happening. He said to service it if no parts are needed will be about $200. That sounds reasonable to me and I should find out more when I speak with the local tech in the morning. Thank you for the advice and if I can't get their help at a decent rate I will start working at it myself.

Will keep posting...
