please help  thanks.

Answer
P044 = Rear heated oxygen sensor is seeing a lean exhaust signal.

I032 = You have a loss of your AUTOMATIC BRAKING SYSTEM and your TRACTION CONTROL SYSTEM serial line data.

What you need to do is CLEAR (erase) ALL the codes by using the climate control panel and then see which codes return.


Without performing any test procedures I would say that you have an intermittent fault in the electric fuel pump in the gas tank.

However, You SHOULD perform the test procedures FIRST.

If you are mechanicaly inclined or know of someone who is, You will need a DIGITAL MULTIMETER, Simple electrical schematics, Test procedures and picture locations of the components within the system that is causing you problems of which can't be done on this website which only allows one picture. I do not have a website so you will have to e-mail: onlineautohelp@msn.com in order to obtain the information.
