Error Code: Crank Position Sensor

[Paddy1337]

Hey guys, I don't frequent the forum much.

Recently, I had a CEL pop, i think code 82, but not positive. Anyway, looked it up and it's crank position sensor. Car still actually runs though...

Anyway, i bitched when the car was new that it had a slight misfire at idle, just a little rough. Others said they have the same issue. Recently my idle would randomly get really, really, bad. Shortly thereafter i got the CEL.

So, i thought, awesome news! a CEL means the dealer will have to do something, unlike their typical fashion of saying they can't find an issue you are describing. This was 2 days before deployment, so I had to move fast. Brought it in with the code on the dash. Next day they say car is ready for pickup. There was no active code, nor a history of a code stored in the ECU. I want to call BS, but don't care too much as I'm deploying the next day.

I have to leave the car there to pick it up after hours (when I friend can drop me off there), because i drove myself to the dealer in my other car. So i get there, start the car, and just as normal, the code is right there on the dash.

So, i feel i'll get it sorted out in the long run when I get home. But I'm really here to ask, have any of you had this same issue? Since others had an idle similar to mine (before it got randomly real bad) i figure maybe this crank position sensor going bad is common for our motors?

Really hoping I don't get the run around on this...

1.4T or 1.8?

I'm guessing 1.8 -because timing belt.
I wouldn't worry if it was a single random crank position error, but if it's recurring, or a 1.4T, immediate attention is warranted.

once a CEL is thrown, the car will run like crap while it's protecting itself in Limp Mode. They probably just cleared the code.

1.4T. i thought i posted in the 1.4 section, i'll double check.

Yeah, i'm surrised it's running, though like i said, the idle randomly goes real bad. But then it goes back to driving like normal. pretty weird. I'm still happy with the car overall, little build quality thigns here and there that I hoped GM had sorted out this day and age...

Definitely reoccuring. And I'm definitely pissed with that dealer.

On a side note, a friend told me that there's soemthing where it has 3 total sensors. Maybe 1 for each cam and then the crank. and if it has 2/3 it can still run. which would be my case. I'm not gunna lie though, this is just my DD, so I can't remember if it's even DOHC or what...

Both 1.4 and 1.8 are dohc
( I think 1.8 for sure)

Wasn't paying attention about the 1.4T section when I clicked.

Yes it's DOHC, and yes it sounds like a faulty position sensor. Take it to a different dealer and play them against each other. Tell the new dealer how you were dissatisfied with the other dealer and that you've been telling anyone who will listen how crooked they are.

The new dealer will probably feed you and then bend over backwards to please you.

Per page 10-12 of the Sonic Owner Manual, Code 82 (Change Oil Soon) message comes up on the DIC when an oil change is needed.

thanks. i'll have to reverify the code when i'm home, or have a friend back home check. it's certainly possible they didn't reset it when i got my oil change (which they almost refused to do because "it was way too early").

i hope that's NOT the case, because then i have to deal with them saying the idle is fine.

I have had oil changes at the dealership and then had to do the reset myself.
