Has anybody had this codes before? Engine light has been coming on and off for the past few weeks, i was able to go down and get it scanned.

What would cause these codes? I have a K&N intake, LSJ downpipe and a muffler.

2007 cobalt ss 2.4

P0010 "A" Camshaft Position Actuator Circuit (Bank 1)
P0011 "A" Camshaft Position - Timing Over-Advanced or System Performance (Bank 1)
P0520 Engine Oil Pressure Sensor/Switch Circuit Malfunction

 

Possibly a short in the intake cam phaser circuitry. Or maybe a stuck solenoid or a stuck cam phaser. Best to take it in. Wost possible case is that your timing chain may have jumped time. That's not very likely considering the intake cam seems to be the only one affected.

 

dunno never had those before, i would take it in and get them to look at it. and if its been raining half as bad in bc as it has in alberta that don't help either

 

ugh, i hope this **** aint expensive

Do you think these sensors would be covered under warranty?

 

They should be. My guess is if you take a closer look you'll find water has made its way into the solenoid. Friend had something similar on his 2.4 cept he threw P0013 and P0014; he had to replace the solenoids but what out of warranty.

 

yaa probaly what he said

 

Where do i find the solenoid on the engine? I will try and take a look

 

They're on top of the head between the #1 coil and the timing chain cover. Two cylinders, one with a black connector and one with a white connector. The one closest to the front of the car is for the intake.

Don't worry the solenoids are only $40 a piece. They'll be covered under powertrain warranty if you have it.

 

I have the engine cover off, you think they will deny it because the engine cover is off an exposing those?

what about the oil pressure sensor? where is that located? Throwing a code for that as well

 

No way in hell.
From what I've heard its screwed into or just below the oil filter housing.

 

alright, thank you, going to make an appointment this week with the dealership

 

How long have you had your K&N filter in? I recently put one in my ION and immediately began experiencing hard shifts, an illuminated engine light, and low and behold a P0011 code. After I spent hours on Saturn, HHR, and Cobalt sites seeing similar issues, I Googled "K&N code P0011". There seems to be more results with this combination than all of my other inquiries combined.

 

K&N has been on for 6 months. It end up being the engine oil pressure switch causing all the problems, which was one of the codes. But when that failed, it caused the other ones to act up since they work in relation with it.

 

Glad it was a simple fix.

 

well i take it back, started laggin betwen 3-4k again, piece of ****** ****

 

It probably needs that intake cam phaser solenoid. I ran into that on my 2.4 not long after I got it. There was a bog in certain RPM ranges.

The dealer likely went after the oil pressure sensor because it -can- affect everything.
