Where's O2 Sensor Bank 1 Sensor 1 for 1997 318is?
OBD scanner shows P0130 (O2 sensor Bank 1 Sensor 1) and P0135 (O2
heated circuit for sensor Bank1 Sensor 1). Autozone says 1997 318is has 4 sensors. 3 before catalytic converter, and one behind. Crawling under the car, I only see 2. One before and one after catalytic converter. Questions: 1. How many O2 sensors/monitors does '97 318is really have? 2. Where is Bank 1 Sensor 1? Thanks in advance. |

To my knowledge, it should have 2, one before and one after the CAT.

Bank 1 Sensor 1 is upsteam of the catalyst.
Your car has 2 sensors, one upstream of the catalyst and one downstream as you have observed and Jeff pointed out and as shwon below. http://www.realoem.com/bmw/showparts...& hg=18&fg=10 liem00 wrote: > OBD scanner shows P0130 (O2 sensor Bank 1 Sensor 1) and P0135 (O2 > heated circuit > for sensor Bank1 Sensor 1). > Autozone says 1997 318is has 4 sensors. 3 before catalytic converter, > and one behind. > Crawling under the car, I only see 2.

A follow-up question.
I ended up buying two universal O2 sensors (#USOS-4000) to replace the existing ones at this place; see the last one on the list: http://replacement.autopartswarehous...nsor&d p=true The old sensors have 4 wires, 2 whites, 1 black, 1 grey. New sensors have the same number of wires and colors. I made wire-by-wire connection, but I still get engine faults: P0130 & P0136. Any idea?
