Oxygen Sensors
When your O2 sensor starts acting up, it’s usually your fuel economy and your DPF that pay the price. These sensors monitor the oxygen levels in your exhaust to help the ECU manage the air-fuel ratio—if they’re sending back 'lazy' or inaccurate data, your engine might run rich, plugging your DPF with soot much faster than usual.
We carry a range of exact-fit oxygen sensors for heavy-duty engines like Cummins and Detroit Diesel, as well as light-duty platforms. Whether you're chasing an efficiency code or a dedicated sensor heater fault, we have the OEM and premium aftermarket options to get your system back in balance.
At DPF Super Store, we focus on keeping Canadian fleets out of the repair bay. Since a bad O2 sensor can eventually trigger a derate or lead to expensive downstream damage, we keep our most popular sensors in stock and ready to ship from our warehouses in Vancouver and Toronto.
You get the same reliability as a dealer part without the massive markup or the long wait times. If you've got a sensor seized in the pipe, don't forget to grab a replacement weld bung to make the install as smooth as possible.
Not sure which sensor fits your VIN? Reach out to our team, and we'll help you find the right match.
