Oxygen sensors assume a key job in motor execution and monitoring discharges. Their motivation is to quantify the measure of oxygen in the fumes, furnishing your vehicle’s PC with data whether the air/fuel blend is consuming rich (less oxygen) or lean (more oxygen). On the off chance that an oxygen sensor turns sour, it can harm the exhaust system (an over the top expensive fix!), lessen eco-friendliness, and considerably increment the measure of hurtful poisons in the fumes.
Utilizing OBDLink’s logging highlight, you can diagram the advances of every oxygen sensors’ voltage (typically there are 2 sensors yet a few vehicles have up to 4), and know when one ends up flawed.
A decent oxygen sensor should create a swaying waveform out of gear, making voltage changes from close least (0.1v) to close most extreme (0.9v) inside 100 milliseconds. Continuously counsel the producer benefit data before making any fixes.
On the off chance that the sensor BEFORE the exhaust system diagrams a straight line, there might be an issue with that sensor
On the off chance that the sensor AFTER the exhaust system diagrams a straight line, you could have an awful converter
Pursue these means utilizing the OBDLink application:
Tap the ‘Logs’ symbol from the Home screen
Tap ‘Menu’ in the upper right
Set ‘Diagram Item 1’ to ‘O2 voltage (Bank 1, Sensor 1)’* – this is the oxygen sensor BEFORE the exhaust system and the upstream stream
Set ‘Diagram Item 2’ to ‘O2 voltage (Bank 1, Sensor 2)’* – this is the oxygen sensor AFTER the exhaust system and the downstream stream
Rehash stages 2 and 3 on the off chance that you have 3 or 4 oxygen sensors in your vehicle
*Terminology might be distinctive for some vehicle’s relying upon year, make, and model.
