I have a 2006 Tucson Limited 2.7. I keep getting the P0133 code. Started happening when I 1st bought the truck a few months back. the 1st mechanic that worked on the car, while changing out the sensor, shorted out every other 02 sensor and the ECU module. The dope had to replace everything, but the ECU was replaced with a used one and reset. The car was ok for about 2 months, and the light(P0133) is back on now, and won't go away. I've been to several mechanics since, changed out bank 1 sensor 1 three times in about a month. It has the hyundai oem sensor, the other 2 prior were aftermarket. Last week, a mechanic had my truck for 3 days, found some bad wires(so he say's), and reset the ECU again. It was fine for a wk, but the light(P0133)came back on yesterday. It's been a brutal($$$)journey, can someone help?. I've changed the gas cap as well. I don't know if they should be focused on the exhaust manifold, MAF sensor, hoses, or should the ECU be the source of my issues?, because after it was reset a wk ago, everything was fine for a week. Usually, the light has come back on minutes after the B1 S1 sensor has been replaced.

sounds like a problem child my thing is why havent any of these shops honored a warranty i think they need to focus on the data from the vehicle and not the code itself

[@arnoldbaerga6908]

ugly HP Exactly!, I took it back yesterday, and he sort of dismissed it as a non issue, I told him I'll be back today because it was a little late when i brought it in.

I also deal with P0133 for a longtime. My solution is just ignore it.

@@shawnfu9292 but if we ignore our problems. they get bigger 😨

Did it ever get fixed

[@qway-p4x]

Thanks, you are a life saver.

My Tucson gave code 1071 often. I could not not tell what's the problem is. But this mass airflow sensor could be one of the reasons. So I replaced one. Hope this can solve it. Whenever worked on the Tucson, I hated their design. For this simple work, they used that kind of clamps. Once the bot was off, it's hard to put it back. You have to be familiar with this kind clamps. It's simply a stupid kind.

point to the arrow for install. Arrow goes to TB

[@abrahamjw7]

why dont not you just clean the maf sensor before to change a new?

[@kevinjohnson8008]

Got the new maf... Still shuts off at lights ?

[@BruceLyeg]

Is there a reason it can't be cleaned instead of being replaced? Also, I'm pretty jealous of your little Milwaukee Impact.

[@uglyhp8225]

the reason is because it was no good

[@BruceLyeg]

Alrighty then.

[@uglyhp8225]

lol i always try cleaning them before selling one but only like 1 out of 5 does the cleaning work

[@kevinjohnson8008]

Question my lady just got one. I discovered this issue.. But the whole square plug with the sensor lead was hanging out

[@uglyhp8225]

do you have a picture

[@kevinjohnson8008]

ugly HP i can take one

[@IBeThirstin]

Hey so I have codes 0507 and 0505 and 0170 I my car was idling high but I cleaned the maf and seems to be running better I haven't checked the codes again but could a bad maf cause all three of those codes?

[@uglyhp8225]

or a vacuum leak

[@lisandraotero6845]

i just changed my maf. the next day, check engine light comes back on and the code is reading the same. what went wrong

[@uglyhp8225]

either you got a bad maf or somewhere between the maf and the ecm theirs a broken wire also possible vaccum leak what code are you getting exactly
