2014 Hyundai Sonata 2.4 MIL Flashing, Loss Of Power Code P1326 

Nice video please keep it up

The check engine light flashing due to knock sensor and constant knocking might be due to several reasons. I own a hyundai sonata and I had this problem. But It was nothing to worry about the engine because it was a factory recall to UPDATE the Sensor Software. Initially the local autoshop told me to use the engine warranty and get a new engine while the engine was totally fine. So, I gave the car to Service center and they Fixed it for absolutely NO COST!!!

Does it do it when it rains or carwash

Sounds like this is what's going on with ours, thanks for the upload

Do you know if changing the oil filter kept it up and running to this day?

Why do you prefer the Hyundai oem oil filters? Do they have better filtration than say, M1?

My car lost power on the freeway when I was accelerating, and the check engine light started flashing. I took it to the the auto part store to scan for codes, but no codes came up. I bought spark plugs and replaced right away. It was running fine but the next day it did the same thing, loss of power, and check engine light blinking. What can it be?

Not the oil filter.

A friend just had the same situation. Loss of power, blinking CEL, but the difference was that a noise started after he got out of the highway. The noise got worse and worse and vehicle stop running. I check the code was the knock sensor one yet once I heard the noise it did sound like connecting rod bearing noise. I could update after the dealer checks it.

Shaking was limp home mode, cuts power at 2000rpm

Hope that is the fix. Had a freind who's 2014 Dart started to run funny after a oil change at one of those fast oil change places. Dealer wanted to change cam phasers etc. She traded it, but it may have been related to oil or filter. These vehicles are so sensitive.

I have a 2017 Hyundai Santa Fe sport and it’s been making a rattling noise when I accelerate and my engine light recently came on and gave me the same code. Had my intake runner motor changed but it’s still making that same noise. And it’s also running through oil very quickly but no oil leaks and no oil lights came on. When it was check it needed 4 quarts of oil. Do you know what it could be?

2014 hyundai sante fe check engine light came on today and was flashing, the code p1326 popped up and was told the whole engine needs to be replaced. no noise but when your start to go it hesitates then goes hoping its nothing serious or expensive.

Mine does this only going thought car wash reset light and it fine only car wash sets it off

👍👍

what if it had a misfire code as well?

Good morning please no update on the p1326 code again

I got the engine light reset and it ran fine

After replacing the cylinder head b/c of a broken valve and driving great for a week, I got the p1326. Lucky the update was done. I wonder how long the new engines last. I have hear some people go thru several engines. It’s almost paid off and I’d like to keep it for another 100k miles.

just had a sonata…. same code same complaint found it to be low on oil…. but recently had oil changed wonder if oil consumption or lube tech didnt add enough oil…. topped oil up cleared codes and been running fine..

Did you ever hear any knock in the engine at all when they brought it in?

My 2012 Sonata have 205,000 kms. on it. Recently, I noticed a flashing engine light was on, I pulled the codes and it was a P1326. I started the engine and it only have less than 1/2 the power. Tried to step on the gas and it doesn't want to rev passed 2000 rpm. I listened to the engine and I don't hear any Rod Knock, so, I cleared the codes and my engine runs normal. It's been 2 days, the code did not came back. I am speculating that there was a glitch in my cars computer or the knock sensor is starting to fail. I have yet to observe my sonata if the CEL comes back, nevertheless, before I turn off my engine, I rev the engine a bit and listen to the engine noise if there is a Rod Knock. All the TSB's and Rod Knock testing was already performed by my dealer in 2019. Hyundai Canada have extended the warranty of my engine to 200k kms. after the last testing. Too bad, I am passed passed the 200k kms. mark.

Any updates?

Please what is EMI

Most likely that engine is done for.

Did not know they did that with the knock sensor but I knew those engine were garbage. I guess been away from the industry to long. 😂

What game is this?
