I just got my Crossfire today and within 5 hours of having it the check engine light came on?
Is there any way to diagnose it?

It is a 06 manual with 30,000.

Thx for the help in advance because im flipping out!

 

If you have an Auto Zone store near your house they will check it for free.

 

Drop by Autozone or Advance Auto and they will read the code for you.

 

Just got back from Autozone and the code is P0131

 

The PO131 code is Front Heated Oxygen Sensor Low Voltage. Nothing to "freak out" about. Easy fix. There is a 99.9% chance that the seller knew this and turned the light out prior to selling it to you. I sell cars on the side and dealers do this to each other all the time at the auction. O2's are a common code.

 

What should I do to try to fix this first?

 

Not a big deal really. The hardest problem I have with O2 sensors is locating the one giving the trouble if you have no diagrams.

The low voltage signal usually means the "heater" in the sensor is defective or open. The heater allows the sensor to warm up faster, to allow the ECM to control the fuel mixture quicker and more accurate. Also it keeps the sensor heated to the proper temperature when idling a period of time when the exhaust runs to cool for an accurate reading.

Until the sensor warms up, the system runs on defaults (open loop). I would think the Crossfire is the same...

Good luck, James

 

If you are good with a wrench and have some simple tools you can fix it. If not just about any tech can put on an O2. This is not a big deal. You will not pass an emissions test right now, but no damage is being done to the car---you are okay. What is happening is the O2 is not sending the correct voltage (approx 5 volts) back to the ECM (car's main computer) so the ECM is going to the rich side just to be safe. Rich waste fuel, but lean will burn valves and then some---so rich is best when the ECM does not get the data it needs. Do get it fix though because if you leave the light on and have another problem you will not know.

I believe it's the front passenger side...?

James1549 is dead on, and so is billangiep. Go with the direct fit. It's more money, but better in the long run. It's the only kind that I would use in my repair shop. The universal ones requires splicing and as I posted we are working with a low voltage and a tight range as well. If the connection is not done correctly, the resistance will be too high thus the voltage too low and you can have the same problem again. Plus, you must insulate them, and if an error is made here, another problem can occur. It's just not worth the small savings. If you have it done at a shop, demand direct fit and ask to see the box.
