Good afternooon!

I purchased a 2007 Sonata with the 3.3L about six months ago. I really like the car, it has a lot of good features and lots of power; however, I am starting to have problems with the car. On accelerating from a stopped position the car almost quits (hesitates severly) and then picks up and goes on normally. Also, between 40 and 50 mph the car starts to jerk pretty hard for a few seconds and then it straightens out and runs normally again; it will do this repeatedly if it is kept between 40 and 50 mph. When this first started happening the CEL would come on randomly and stay on for a day or two and then go off. While the CEL was on I took it to Autozone and had them pull the code, they said it was the crankshaft position sensor. Well based on the symptoms the diagnosis made sense. I replaced the sensor and the car seemed to be running normally on the 30 minute test drive. The next day my wife drove to work and she said the same symptoms had come back. It has been several weeks since I replaced the sensor and the CEL has not come back on. I have seen several postings about the spark plugs and wires and that is my next step. Just in case this doesn't work, has anyone else had this problem or know a fix for it? BTW the car has 94k miles.

Thanks,

C

3.3 Lambda does not have spark plug wires.

Most common issue with accell is when you step on pedal and there is no response.. or limited power,, and typically the MIL, ABS/ESC lights illuminate.

Scan will usualy bring a 2135, 2106, 1295 as a 3 code set, that leads to a 35107-3C100-FFF TPS replacement and PCM upgrade to latest version of sooftware.

Ok, so on my way home yesterday the CEL finally came on. I stopped by autozone to pull the codes and this is what I got:

P0430, P0012, P0011

According to the Haynes manual I have for this car, P0430 is related to the emissions control, P0012 and P0011 are related to the cam timing. The Autozone tech said that it was probably the cam position sensor and O2 sensors. So, if what he said is correct then the cam being out of time or misfiring is causing fuel to be burned incorrectly which is what's causing the emissions error, maybe? The cam position sensor for this car is about $100 and from what I can tell there are about 4 O2 sensors. Is there anyway to positively identify the cam position sensor as the problem, and if the O2 sensor is bad how do I know which one it is? Any opinions, expertise, or experience with these codes would be greatly appreciated. I would like to have a little more reassurance before I start replacing parts.

Thanks!

I was just told there are two cam position sensors on this model Sonata. Is that correct? If so is there anyway to tell which one is bad?

Based on the information you have provided, I would replace the intake cam sensor (front cam) and see if that resolves the cam position and Catalytic converter issues. With a bad cam sensor there are bound to inefficiency issues as a result and those will probably be resolved with the cam sensor replacement.

Nope, oil control valve for bank 1 cam timing.. 1 of them is easy,, the other requires full removal of upper and lower intake manifold.

0430 should be a cat efficiency code, have to double check though..

I can't find anything on the oil control valve. What does it look like and where is it located?

Not look in right place -- Valve #1 is the item you interested in.. see picture :



NOTE - picture reflects that needed to access/replace the #2 valve.. #1 can be done with intake still attached to engine.

I did some more research concerning this problem and found this TSB from Hyundai.

http://pages.suddenlink.net/daydreamer/Cou...0INSPECTION.pdf

I guess I will take the OCV out tonight and follow what the TSB says.

One more question. I have searched and searched and cannot find an OCV replacement anywhere, any suggestions?
