Good morning,

What model is your chevy?

Are you getting any other symptoms or just the check engine light?

I'm sorry, did a phone call thing pop-up? That's not me. It's automated.

I need to know the model of the vehicle. Is it a silverado, a malibu, an impala....

2006 HHR

Chevy Mechanic: Jared D, ASE Certified Technician replied 9 months ago

So on the HHR this code pulls up when there is an imbalance between the air and fuel ratio. This doesn't have a specific cause because a number of items can affect the air and fuel ratio. The first thing to do is to check for air leaks. Hre are a couple of things to check.

  • Check the vacuum hoses for splits, kinks, and improper connections.
  • Check for vacuum leaks in intake manifold, throttle body and injector O-rings
  • Check for air leaks in the PCV system and in its related hoses and/or valve

If no leaks can be found the next thing to check for is a fuel condition problem.

Have you recently filled up on gas (like right before the code triggered)?

Also, how many miles do you have on you vehicle?

Fuel injectors are known to clog on this model, but usually only after a certain mileage. If you have high enough mileage then a fuel injector and upper engine cleaning might clear up the codes you are seeing.
