Strange Issues. Please help a brotha out.

so dont replace Camshaft Positioning Sensor. Replace Front Hub Bearings instead?

Two separate issues.

I’d change the (edit: Crankshaft) position sensor and then see what happens. Sometimes a rough running motor will trip your Stabilitrak and Traction Control due to vibration. Mine has set off those codes on rough washboard gravel roads.

Definitely the sensor first. Stabilitrak is just a nuisance for the most part.

Do check your identification of the code. I have a subscription to Mitchell for my 2008 and for mine P0335 is the Crankshaft Position Sensor.


@soulsea maybe you can help this guy out by moving this to the correct generation forum?

ok, funny thing is it doesn't show any messages regarding Stabiilitrak until after it runs for 10mins.

You may still need the cam sensor and likely do because of the engine dying and the code but I would go ahead and get a good quality one and have it in case and get plugs if the inspection shows are needed and wires at the same time but the other concerns about stabilitrak and such are likely related to the hub/bearing/connectors/wiring area. You very likely have at least 2 problems. I am now assuming there was not much inspection done before you bought it. Any old paperwork and/or info supplied about maintenance and repairs? Did you get a CarFax? You would not have known about the cam sensor unless there was a code for you to retrieve with your scanner. The hubs may have been seen on a close inspection with tires on and off. Lots of unknowns at this time and like has been said, basics first instead of throwing parts at it. Hopefully you have another vehicle while you get thru this.

Welcome to the forum from Oregon

@Fless he said in first post was a 2007 GMC XL Denali but was in the wrong section. Like has been said by @wjburken and @Bill 1960 said, complete codes are needed.

Also been said, the front likely has a bad hub bearing or two and when replace, for the love of God, don't go cheap. get Timken or AC Delco. May also just have some wires/connectors causing the problems at those wheel speed connections. If you have no idea on the age of the plugs and wires you again can get some good quality AC Delco parts for that but the plugs may look great. Pull one or two on each side and post pics here for recommendations. You will get there eventually with the fix on these problems.


May end up with one of these too. https://www.rockauto.com/en/moreinfo.php?pk=993793&cc=1433459&jsn=2045

Isn't P0335 a CRANKSHAFT position sensor code? Not camshaft?

 

[OR VietVet]

Yes, I was responding to his description instead of verifying. P0335 is all about the crankshaft position sensor. Hopefully he reads this but if it was me, I would replace both of them.

I am guilty of not verifying the P0355 code as well.

Hey, stuff happens.

Yes, my bad. Crankshaft position sensor.

Yes, my bad. Crankshaft position sensor.

replace it and have a relearn done, you may have to have the relearn done as soon as it is changed if it won't start and make it to a shop
after that is done if your stabiltrac light is still on then you need a better scan as those codes can be bcm codes and require a scanner that can read them like a tech2 or snap-on, etc
