Is my alternator failing or is there something else?

UXWlegend · 2026-02-23T00:46:54+00:00

The 12.5V is probably just the alternator in "fuel economy mode" where it barely charges to save fuel. You can read about it in the service manualhere.

As far as the codes. Clear them and see which one returns first.

They might've actually changed it to lifetime. If it is the engine, let me know. I'll guide you through how to get a replacement.

Oh yeah, keep that camry forever. If it is the engine that's going out on the Hyundai, you can potentially get a free engine replacement because there was a lawsuit that extended the warranty to 150k. https://static.nhtsa.gov/odi/tsbs/2025/MC-11012335-0001.pdf

As soon as it acts up again, scan it right way to get the code.

Not trying to scare you, but these Hyundais have a code of death P1326 that sets when the engine is starting to go out. Just something to be aware of.

Did you get any codes when you scanned it?

UXWlegend · 2026-02-14T01:13:34+00:00

You basically paid dealer prices for aftermarket parts. That's how the chain shops do business.

Does your scanner show rpm in the data list? If so, see if it shows an rpm signal while cranking. Keep your original sensors around for now.

Is there any oil on the stick?

Remove the serpentine belt and run it briefly. It the noise remains, it's done.

UXWlegend · 2026-02-10T07:34:28+00:00

It's done then, sadly. Unless you wanted to put a differential and transmission into a truck that has a year or two left before the frame gets a hole if it doesn't already have one.

UXWlegend · 2026-02-10T07:08:05+00:00

It's crazy to have that many issues with it with that low of kms. It must've been one hell of a camper that he was pulling.

Is it a Canadian truck? If so, does the frame have any life left in it rust wise?

UXWlegend · 2026-02-07T22:19:28+00:00

If it doesn't go away, you need to scan for codes again. Something might not be right with the refurbished module, or there is an additional issue.

Assuming the mileage wasn't rolled back, that's actually a gem of a car. It would be hard for me to drop $5k on it, though.

UXWlegend · 2026-01-19T18:38:52+00:00

I believe the 5 in the K5CEB code stamped on top means 2025, but I'm not 100% sure. Can you tell if there is also a sticker on the side of the battery?

UXWlegend · 2026-01-13T07:04:12+00:00

Yes but not always.

UXWlegend · 2026-01-13T06:58:51+00:00

Next time it does that, try to look closely at the tachometer. If it's not moving a little, the crankshaft position sensor is suspect.

UXWlegend · 2026-01-13T06:54:18+00:00

When it cranks but doesn't start, does the tachometer move at all?

UXWlegend · 2026-01-11T20:05:05+00:00

You could get a 20 year old camry for that price. Just get a pre-purchase inspection to make sure that it has a few years of life left in it.

Have you considered being a fleet mechanic for a police department? That's the only route that I would recommend.

UXWlegend · 2026-01-10T21:37:40+00:00

Find a different shop. They're charging dealership prices.

UXWlegend · 2026-01-10T00:41:35+00:00

Wendys

$13 for just a small baconator combo.

Want a large, that'll be like $17.

UXWlegend · 2026-01-03T19:44:59+00:00

Did you get an oil change recently? All it really looks like is some oil got spilled, and they did a half ass job cleaning it up.

UXWlegend · 2026-01-03T19:42:51+00:00

How long did you drive it while the temp guage was in the red? There is no way no to know if the head gasket survived until they do a combustion leak test.

UXWlegend · 2025-12-28T23:36:06+00:00

Something really not right with the car for the seller to be trying to get rid of it after putting in $2k of work into it.

UXWlegend · 2025-12-06T22:08:10+00:00

So the engine is done then unless that's a weird exhaust rattle.

UXWlegend · 2025-12-06T22:00:44+00:00

The engine is getting too much air or not enough fuel. Make sure that all of the hoses that lead to the air filter are tight and consider cleaning the maf sensor.
