My daughter's 2004 Mitsubishi Endeavor's (3.8 V6) MIL came on and I scanned it. It's a O2 sensor heater code on Bank 1 Sensor 2. Now I know Bank 1 refers to the bank that has #1 cylinder on it and of course Sensor 2 is the one downstream from the convertor. My question is: Is Bank 1 the front or rear bank? I have heard both sides and I know each manufacturer can be different.
Thanks in advance...
