1998 Mitsubishi Eclipse Question: Bank 1, Sensor 1
Answer #1Bret Bodas from RepairPal Test Shop, May 27, 2010, 12:56Master
Sensor 1 refers to the O2 sensor in front of the catalytic converter. And bank 1 is not relevant, this only has one bank. (V6 and V8 engines have a bank 1 and 2, not 4 cylinder engines)
