Important tips for maximising your oxygen sensor’s service life.


Here we have important tips to increase the service life of your oxygen sensor, including positioning, coordination and air calibration.

With the Innovate Broadband Oxygen Sensor, you can carefully monitor the engine’s air/fuel ratio. Especially with tuned engines, it is very important to keep an eye on the oxygen sensor value, as this acts as useful life insurance, boosting your engine’s service life. Many vehicles have a fixed, specified value under full load so that you don’t notice whether the engine is running too lean or too rich in serial condition. In addition, the display has a wide measuring range of approx. 0.5 to 1.5. In order to optimise accuracy, positioning and calibration are very important.

Attaching the oxygen sensor:

Ideally, the sensor should be approx. 60 cm downstream from the cylinder head outlets when the exhaust gases flow through the exhaust pipe. Condensation formation can destroy a sensor very quickly. Preferably, the sensor should be installed at between the 9 o’clock and 3 o’clock position. This protects it from water on the underside of the exhaust pipe. The ideal installation is in the 12 o’clock position.

This ensures correct measurement.


The stainless-steel welding ring must be welded in cleanly so that no fresh air can enter the air flow.


To calibrate the oxygen sensor, it must be connected and enveloped by fresh air (not installed). Only this way can a broadband oxygen sensor’s accuracy be ensured. The display shows CAL during calibration.


After about 3 months, the oxygen sensor should be re-calibrated in order to maintain its accuracy. Excessively rich air/fuel mixtures as well as incorrect sensor placement or oil consumption can shorten the sensor’s service life.
