•
For the primary oxygen sensor, the sensor should be located in the engine exhaust outlet as close to the
merge of all cylinders as possible but prior to the catalytic converter (if equipped).
•
In some cases on multiple bank engines (V-block engines) it’s possible to obtain acceptable
performance using exhaust gas from only a single bank although the preference if possible is at the
merge of both banks.
•
For the post-catalytic oxygen level sensor ensure the selected mounting location is mounted near the
catalytic converter in order to provide accurate data.
•
In turbo-charged applications the sensor must be installed no closer than 18 in. [457 mm] away after the
turbocharger outlet.
•
The SOX 102 sensor heater circuit is 12-14V capable only.
•
The SOX 102 sensor is provided with a 1/4” barbed fender plug in order to secure the electrical
connection point
