5.1 O2 Sensor Installation
The sensor must be inserted in the exhaust system with its tip exposed to
the exhaust gas flow. It must stay in an angle between 10 to 80 degrees to
horizontal position, that is, with its end downward, in such a way that steam
droplets cannot be accumulated between the body of the sensor and its ceramic
part, which could cause damage when the sensor is used. The sensor must
not be placed vertically, as it becomes subject to excessive heat.
It is recommended that the sensor is installed at least one (1) meter away
from the exhaust manifold to avoid excessive heat, and at least one (1) meter
away from the exhaust external output to avoid incorrect readings caused by
oxygen in the air outside the exhaust system.
Notice that such recommendations are not obligatory, as vehicles with a smaller
exhaust system will need to have the sensor placed closer to the engine.
The sensor must stay away from the cylinder head and from areas where one
cylinder might affect the exhaust air more than the others must. Avoid placing
the sensor close to the exhaust manifold joints, as some allow the inflow of
air, resulting in incorrect readings.
