my car is 2001 Diamante LS, 6 cylinder. Failed on SMOG check, it's the O2 sensor, ( Bank 1 Sensor 2 ), can someone help me locate that part that i can buy it online, the quote from dealer is $240.00 which is too much.The error code is "PO141 O2 sensor heater fault(bank 1 sensor 2)" and "PO 401 EGR " .[:@]
