I got a CEL on '99 SE-L (Cali spec) and used a scan tool in the shop to see what's wrong. It came up with O2 sensor bank 1 sensor 1. Now, does that mean front sensor driver's side or passenger's side (or something else)?

Please help me out, I need to know which sensor to buy since I'm going to be installing Warpspeed Y-pipe tomorrow and want to replace this O2 sensor as well.

Thanks,
Mike

 

go to www.oxygensensors.com - good prices, and free shipping over $50 or so. Bank 1 is the one on the left (front) side of the engine, closest to the exhaust manifold.

 

You mean front sensor driver's side (LH)...that's what I thought but just wanted to make sure, thanks.

I know about that site but can't wait for the shipping since I want to install the Y-pipe tomorrow.
