I've been getting all three faults simultaneously: check engine, cruise cuise control (doesn't work, the light keeps blinking on and off), and traction control light comes on and will not work.
The diagnostic machine reads the check engine fault as O2 sensor bank 1, sensor 1.
My battery died last week so I replaced it. This cleared all the codes for about 300 miles and all three faults returned.
I tested the battery and it said it needed to be charged. This is a one week old battery. I removed the battery from the car and tested it and it was 100% good. The alternator is also 100% good.
I'm guessing there may be an issue with the terminals. I do have a problem with one of the terminals; the terminal is too small for the clasp that goes around the terminal. Meaning when I tighten the clasp down it is still loose and can be pulled right off the terminal with ease. I temporarily have a small screw between the terminal and the clasp so the clasp can tighten and not come off so easy.
I do have the replacement bank 1 sensor 1 oxygen sensor and plan on getting that installed. Any suggestions on the battery issue?
Thanks in advance.
