need some help with error codes

Mustangless · Aug 15, 2004

My car is getting really bad gas mileage so I ran these codes.

175 - Heated oxygen sensor unable to switch, left side
176 - Heated oxygen sensor indicates lean condition, left side
632 - transmission control switch circuit did not change states during KOER
116 - coolant temperatre sensor out of self test range

I think I need a new o2 sensor on the left side and a ect sensor... does this sound good?

also what about the 632 code. Could this be my shift kit?

If it were my car i would probably just get a new o2 sensor or both..just depends on you since it does sound like one of them could be bad..if you want you can check all of your sensors with a voltmeter just to be sure before you purchase..i would also just get a new ECT(engine coolant temperature) sensor since there only like 18 bucks anyways...The 632 is prob nothing you probably didnt press your overdrive button during the KOER test..your also supposed to turn the wheel a 1/4 turn and press the brake pedal also..Anymore questions just PM me.
