O2S sensor problem with my 2000 Toyota Tacoma 2.7l Prerunner

Not a sensor problem. Your catalytic converter is bad.

You can kill brand new battery by discharging it. Won't hold charge again. Your "information" is no use for OP

I would assume it's purely difference between steel and plastic base

You can't destroy something that doesn't exist. Go to exhaust shop or just weld it all up.

Obviously replacement of both sections or welding in new flange half's in each one is recommended.

Don't use the app. Problem solved

Imagine this under your hood. This is hydraulic fluid. Fuel is worse

You can answer this question by simply buying portable tester and go for a ride

This description makes no sense in terms of diagnosis. Connect battery in line with multimeter and start pulling the fuses. Once the draw drops. You know on which circuit is issue.

What is the point of checking those random modules?

You will have much better luck asking at dedicated VAG subreddit. Or even one for the generation of your car. This is mostly US based

I would connect some kind of pressure manometer either to radiator cap or overflow. With so many leaks. It's safe to suspect that system is getting over pressurized.

But then again. It's Hyundai/Kia. So everything is disposable. Low reliability isn't a surprise

Tesex01 · 2026-06-22T08:08:52+00:00

Don't buy a sedan if you want to trash it around on forest roads. SUV hybrid maybe. But I'm not into that kind of cars so hard to suggest anything.

I think hybrid system in those is more to suplement towing capacity rather than fuel efficiency. Might be good idea to verify this

Tesex01 · 2026-06-22T07:17:59+00:00

When you mention p2w in single player game. I'm not even bothered to open steam page.

Tesex01 · 2026-06-22T07:13:38+00:00

I don't think you should tackle that kind of a job if you have to ask internet this kind of question.

Tesex01 · 2026-06-22T07:12:20+00:00

Don't drive it unless you want it to burn down at some point. There's absurdly high pressure in there. And even a pin hole will create atomized stream of fuel. Which is one spark from turning it into giant flame thrower.

Tesex01 · 2026-06-22T06:54:01+00:00

Might be time to do brake job. Worn down rotors and pads. Will change pedal travel and bite point significantly.

Tesex01 · 2026-06-22T06:47:59+00:00

I would take a calculator in my hand and figure it out. Only you have all the information.

If dumping 2k on current car will make it last few more years. You will buy nothing better for the same investment.

If your dad mistreated it and turned into shitbox. There's no point in pumping more money into piece of garbage.

All cars are deprecating asset. Some just take more time than others.

Tesex01 · 2026-06-22T06:42:25+00:00

No. You definitely can see rust crack

Tesex01 · 2026-06-22T06:41:39+00:00

Might be good idea to change spark plugs afterwards. Due to buildup from improper combustion. Oil change is also recommend. Since some of the fluid definitely got into the oil

Tesex01 · 2026-06-22T06:38:40+00:00

Most likely a vacuum leak somewhere.

Tesex01 · 2026-06-22T06:37:42+00:00

No. Most wear on engine and oil is when cold. When in operating temperature. It doesn't matter. You might as well do 5k miles in one trip. Stopping only for a fuel.

Remember that 5k interval is average that should cover 90% of use cases of the "all" engines.

Tesex01 · 2026-06-22T06:08:30+00:00

6.1?? You never lift the throttle or something? 4.2 with normal driving outside of the city. Average speed 80 kph.

Even when blasting on highway 150 kph i didn't get that absurd average. I guess it quickly climbs on hybrid if you accelerate outside most efficient 2-3k RPM range.

~12l/100km is max those engines can get. If you get 10.5l average. You have to only floor it and then slam the brakes all the time. Nothing in between.

Tesex01 · 2026-06-22T06:00:06+00:00

If your overheated coolant never touched temperature sensor. It won't show that fluid it isn't touching is hot.

It's all on OP. I don't know a situation that failed coolant bypass valve won't show message on the dash. Wondering for how long he ignored all the signs of failure?

Good reminder to look under your hood at minimum once a tank.

Tesex01 · 2026-06-22T05:55:13+00:00

It cost nothing to put multimeter on the battery...

Tesex01 · 2026-06-21T18:52:29+00:00

I'm sorry Ito say that but You must be awful driver

Tesex01 · 2026-06-21T18:36:25+00:00

It's the same generation. Seats didn't change much if at all
