I have searched high and low and not found a list of diagnostic trouble codes for 2007 Corvette. I found plenty for C5 Corvettes but not C6.At 6,400 miles I recently encountered the following code: P2A01 Could anyone help me with this particular code or a list of codes for 2007 Corvette?

 

DigitalCorvettes.com has a list.

From the list:

P2A01
HO2S Performance Bank 1 Sensor 2
ECM
DTC P0133, P0134, P0140, P1133, P2270, P2271, P2A00, or P2A01

Thanks very much for the information and quick reply

 

Do you have any ideas regarding what would cause this code? I'm not sure what a 'performance bank' is. I have added Melrose headers, a VaraRam intake and a 160 deg thermostat to this point. No tune. Any help kindly appreciated.

 

No I don't. I suggest you start a new thread, probably in the Tech section, titled "P2A01 Trouble Code ?????". Put in the explanation that you have right now. You should get an answer fairly quickly. If not, then bring the same question back here to General.

You could also send a PM to GMautotech. He isn't logged on right now but he will be later. Here is the link to his profile:

Good luck.

 

Something to do with Heated Oxygen Sensor & low voltage.

 

I have also sent an inquiry to Ken Fichtner where I purchase the Corvette to see what they can tell me. Thanks for all help and replies. I will follow your advice on the new post.

 

It sounds like the headers might be causing the DTC's. With the headers you probably eliminated, disconnected or moved the location of the heated O2sensors. The delta between the hot and cold sensors is not what the vehicle is expectinng.

We need a techy to chime in here.

 

DTC P0133 or P0153
Circuit Description
Heated oxygen sensors (HO2S) are used for fuel control and post catalyst monitoring. Each HO2S compares the oxygen content of the surrounding air with the oxygen content in the exhaust stream. The HO2S must reach operating temperature to provide an accurate voltage signal. Heating elements inside the HO2S minimize the time required for the sensors to reach operating temperature. The engine control module (ECM) supplies the HO2S with a reference, or bias, voltage of about 450 mV. When the engine is first started the ECM operates in Open Loop, ignoring the HO2S voltage signal. Once the HO2S reaches operating temperature and Closed Loop is achieved, the HO2S generates a voltage within a range of 0-1,000 mV that fluctuates above and below bias voltage. High HO2S voltage indicates a rich exhaust stream. Low HO2S voltage indicates a lean exhaust stream. This diagnostic will only run once per ignition cycle. The ECM monitors the rich-to-lean and lean-to-rich transition time. A transition is defined as, the HO2S voltage changes from above 625 mV to below 250 mV or from below 250 mV to above 625 mV. If the ECM detects that the transition time is too long, DTC P0133 sets for HO2S bank 1 sensor 1, or DTC P0153 sets for HO2S bank 2 sensor 1.

Have you made any changes to the car? Did you have a tune? Have you added headers? Have you run over any debris that could have potentially damaged one of your O2 sensors?
