Lambda and level sensor

The VOLTREK lambda sensor measures exhaust oxygen for an optimal mixture; level sensors monitor oil and fluid levels.

VOLTREK lambda sensor with cable and connector

The lambda (oxygen) sensor measures the oxygen left in the exhaust gas. The control unit uses it to hold the air-fuel mixture at the right ratio so the catalytic converter works efficiently and consumption stays low. Level sensors measure engine oil or other fluid levels and warn when they drop.

VOLTREK designs these sensors for short response time, stable signal, resistance to high temperature and vibration, and connector and cable length to the original part.

Frequently asked questions

How many lambda sensors does a vehicle have?
Usually two per exhaust line: one upstream of the catalytic converter that controls the mixture and one downstream that monitors catalyst efficiency.
