Why hello there! :)
Buying lambda sensors can be a little tricky! Even with a vehicle registration plate the data will only show us the variants of lambda sensor available and in a lot of cases there is more than one possible lambda sensor fitted to a car, so it is a case of having to do some research and digging around to ensure you get the correct unit for your car.
So, what should you check?
The part number – Part numbers are king! You will usually find your part number either across the lead or on the plug itself. We include original part numbers in every listing in our description and item specifics and it’s really important that this is checked. If you are unable to check this manually then we strongly recommend you give the main dealers a call to try and get it from them.
Do I need pre or post cat? What is pre or post cat? What’s a Bank 1 or 2?A Pre cat (before the cat) sensor is positioned in/near the exhaust manifold, before the catalytic converter. A Post Cat (after the cat) sensor is positioned in the exhaust system after the catalytic converter. We list whether a sensor is pre or post cat in the item specifics so please check this :)
You will find however some vehicles have the same sensor for pre and post.
If your vehicle has had a diagnostic test you may for example have a code displayed “sensor B1 S1 faulty”. So what does this mean, what is B1 or S1? Well what this is suggesting is that Bank 1 Sensor 1 is faulty for example. Here’s an image below to help you identify what this translates too, because let’s face it, pictures are so much easier!
Lead length – Please check the overall lead length of your lambda sensor and check our listing as we include lead lengths in all of our listings to help you make an informed decision
Plug type – Some lambda sensors differ by the shape and colour, so please do check this if you can :)
