On my way to calgary my car threw the intake camshaft sensor code, my vvt was acting funny. got it cleared at the dealership, came back as soon as I got threw edmonton tonight. cleared it again about 2 hours ago. has not came back, any one else have this issue?

car was factory when it did it. no mods to the engine at all.

code p0011

and threw code u2105 for some reason on the security system. thats not to big of a worry.

 

P0011- Camshaft Position Timing - Over Advanced (Bank 1)

Don’t know how that could of happen, unless the mechanism for the VVT solenoid is not working right.

 

ok cruisn as i promised here is the description for the P0011 code.

Circuit/System Description
The camshaft position (CMP) actuator is attached to each camshaft and is hydraulically operated in order to change the angle of the camshaft relative to crankshaft position (CKP). The CMP actuator solenoid is controlled by the control module. The control module sends a pulse width modulated 12-volt signal to a CMP actuator solenoid. The solenoid controls the amount of engine oil flow to a CMP actuator. The CMP actuator can change the camshaft angle a maximum of 25 degrees. The control module increases the pulse width to accomplish the desired camshaft operation.

and this is everything that they have to test for this one code.

Circuit/System Verification
Ensure the vehicle has the proper oil viscosity.
Observe the engine oil level. The engine oil level should be within the operating range.
Allow the engine to reach operating temperature.
Increase the engine speed to 1,500 RPM.
Command each CMP actuator to 25 percent. The CMP actuator angle desired parameter should match the CMP actuator actual parameter.
Circuit/System Testing
With the ignition ON, measure for battery voltage between the CMP actuator solenoid control of the affected actuator and a ground.
⇒ If less than battery voltage, test the CMP actuator control circuit for an open, short to ground. If the circuit tests normal, replace the control module.

Connect a test lamp between the CMP actuator solenoid control of the affected actuator and a good ground. The test lamp should not illuminate.
⇒ If the test lamp illuminates, test the CMP actuator control circuit for a short to voltage. If the circuit tests normal, replace the control module.

Command each CMP actuator solenoid between 0-50 percent. The test lamp should turn ON and OFF.
⇒ If the test lamp does not turn ON and OFF, test the CMP actuator control circuit for high resistance. If the circuit tests normal, replace the control module.

Connect a test lamp between the low reference circuit of the CMP actuator solenoid of the affected actuator and battery voltage. The test lamp should illuminate.
⇒ If the test lamp does not illuminate, test the low reference circuit for an open, high resistance. If the circuit tests normal, replace the control module.

Determine that the vehicle has the correct engine oil. Refer to Service and Appearance Care in the owner's manual.
⇒ If the engine oil life system monitor displays the Change Oil Soon message, the engine oil is more than one year old, contains additives, or is not the correct viscosity, change the oil.

Test the engine oil pressure. Refer to Oil Pressure Diagnosis and Testing .
⇒ If the oil pressure is low, correct the low pressure first.

Inspect each CMP actuator solenoid valve assembly for the following:
• Torn screens

• Debris on the screens

• Debris clogging the oil ports

• Missing screens

• Oil seepage at the solenoid connector pins

Inspect for the following conditions:
• Excessive timing chain play

• Proper installation of the CMP actuator assembly

Component Testing
Measure the resistance of each CMP actuator solenoid valve assembly. Resistance should be between 8-12 ohms.
Connect a jumper wire between the CMP actuator low reference circuit at the solenoid and a good ground. Connect a fused jumper wire to the CMP actuator high control circuit at the solenoid. Momentarily touch the fused jumper to B+. Observe the spool valve inside the CMP actuator. The spool valve should move from fully closed to fully opened position.

 

thank ya thank ya. lol. well off to the dealer I am. this sucks.... that would be why the vvt isnt kicking like it should.

 

probably and from most of the testing steps it looks like the control module will be replaced. because 4 out of the 5 steps say to replace the control module lol. the other one just says to change engine oil

 

the oil was jsut done last week. and its all topped up.

 

ya i know thats why i find it funny so i would tell the dealer you take it to that you just did your oil change.

 

5-30 castrol syntec. nothin but.

there gonna harass me anyways, always do doesnt matter where I go. you lowering springs caused this malfunction, most likely they will try to blame my exhaust setup which wasnt on when it threw the code. lol

 

curious to find out what they say. update us when you find out.

 

ya well tell them to shove it. cuz exhaust systems don't void warranty you heard that from my shop foreman. and don't feel left out anymore my car just threw a code tonight and wouldn't ya know i can't get it scanned till monday damn it.

 

will do.

and sorry to hear outta, lol. it sucks having that light on.

 

ya it came on last night while i was driving on deerfoot. around the same turn it happened last time. i was just driving casually. put the cruise on as i was feeling a little lazy and no one was on the road last night. and then next thing i know i look down and the lights on. well looks like its gonna be booked into the shop.

 

so i got my code scanned it was P1174 - Fuel Trim Cylinder Balance. so basically my injectors are getting clogged and now to prevent any damage im throwing an injector cleaner into the fuel and running strictly 91 octane in her. my P0300 - Misfire code is related to this as well.

 

that crap doesnt help. if anything it might have caused a misfire i just had recently lol

 

actually thats what the technicians use to clean your injectors. its the gm stuff which is alot better quality then what you buy at canadian tire or any of the other stores.

 

Yeah I used Lucas Oil injector cleaner or some **** from Autozone. Waste of 4 bucks.

 

ya i spent 13 and that was my cost the stuff regularly costs like $26 and thats what all my shop foremans and our top driveability tech is recommending so i'm gonna trust them but either way even if this stuff only gets most of the injectors clean running 91 octane will help with the rest of it.

 

yeah but ive been running 93 for a year now

 

ya are you s/c or n/a hard to tell from alot of people changing wings and such.

 

N/a 2.4

 

ya thats what i am. i ran 87 octane for the last year and not a problem and it ran fine but now i've been getting misfire codes and then the fuel trim balance code and those together have the potential to really screw up my motor so i figure its not worth running 87 anymore.
