Oxygen Sensor follies

[Courtney V. Bearse]

The front O2 sensor is a the "real" O2 sensor. By real this is the senor
used by the ECU to monitor lean/rich conditions. BOSCH makes the OE
model, part number #13039.

The rear O2 sensor is used to monitor emissions after the cat. NGK/NTK
makes the catalytic sensor, part number# 24075.
