Lambda sensor testing and troubleshooting | HELLA

The broadband lambda sensor offers the option to measure a precise air ratio in both the lean (λ > 1) and rich (λ 1) ranges. It delivers an exact electrical signal and can therefore control any reference values – for diesel engines, gasoline engines with lean concepts, gas engines, and gas heaters. Like a conventional probe, the broadband lambda sensor is built up with reference air ...

Oxygen Sensors: What Happens When O2 Sensors Age or Die ...

· An O2 sensor can be tested with a probe by attaching one lead to the signal wire and the other to ground to check for voltage. These sensors read an increase in oxygen as a lean condition and should produce close to 200 mV ( V). The sensor is bad if it doesn’t respond or is slow to respond. In that case, a vacuum leak or some other component could be the culprit. Be sure the voltage is ...
