CEL Part 2

Thanks for the help, I found the OBD II socket... So, I threw in a code reader and it read P0155 - O2 Sensor Heater Circuit Malf (Bank 2 Sensor 1). Also found a Denso O2 Sensor in eBay for $55. Questions are: 1) Where exactly is the bank 2 sensor 1 located? 2) Is it the only sensor located on bank 2? 3) Is the job (replacing it) way too difficult for a weekend warrior - hey I can change the oil/filter... Any advice/tips.. Thank you.

The 100 series has four oxygen sensors, a pair on the driver's side exhaust pipe and a pair on the passenger side exhaust pipe, before and after the cat converter. As I understand it, Bank 2 - Sensor 1 is the passenger side, before the cat.

I've got the same code (in addition to the P0135), but I haven't changed the sensors yet. I don't think it'll be too difficult.

Search the forum and you will find a post dealing with this issue i.e. the installation and removal of the o2 sensors.

That's the thread that seems to be the most useful. I've been riding around with that code on for a LONG time now. Hope to get it taken care of before the real heat gets here.
