Expert:  Joshua Haynes replied 6 months ago.

It's ok, I don't need a phone call, sometimes the system will automatically ask for one

Customer: replied 6 months ago.
ok thats fine any ideas on the code ? its a co561
Expert:  Joshua Haynes replied 6 months ago.

Is this the only code you have? usually this code will come up as an indicator that there is a code in either the engine or transmission control module that is preventing it from performing its traction control duties

Customer: replied 6 months ago.
only other code i have are lean codes bank 1 and bank 2 i dont belive that either of those will caused this with the traction control
Expert:  Joshua Haynes replied 6 months ago.

Actually, those codes would be very likely to cause the traction control code c0561. The traction control system relies on having control over engine torque reduction and if there are mitigating factors such as a lean condition, it cannot do this reliably and will therefore shut off the trac system and set this code. Is your "trac off" light also illuminated?

Customer: replied 6 months ago.
currently no its not but i do believe it is when the code sets should i check o2 senors and monitior those while driving or bay test
Expert:  Joshua Haynes replied 6 months ago.

Ok, that all adds up then. Yes, you should monitor oxygen sensors and I suggest doing that while you are spraying a flammable liquid such as brake cleaner near the intake and vacuum lines as the most likely cause of a lean condition is a vacuum leak. I also suggest checking fuel pressure and volume with a gauge as this is another possible cause of those codes, especially if you notice a reduction in pick-up. Good luck and don't forget to take a moment and leave a positive rating!
