different engines, different systems...what is yours?

oxygen sensor location is very important

downstream? upstream? pre-cat? post-cat? what is it?

 

 

Upstream
  • The upstream oxygen sensor is located before the catalytic converter.  ( FRONT )
Downstream
  • The downstream oxygen sensor is located directly after the catalytic converter.  ( REAR )
 
 
Location: Oxygen sensors are always located along the exhaust path and before the tailpipe. In vehicles with only a pre-CAT O2 sensor the sensor will be located either directly before the catalytic converter or on the exhaust manifold.
 
 In vehicles with both a pre CAT and post CAT oxygen sensor, one sensor will be located directly before the CAT and the other directly after.
 
 Vehicles with dual exhaust systems can have up to four oxygen sensors monitoring exhaust streams on both sides of the engine. Dual bank and dual exhaust engines are typically V-6 or V-8 models.
