The Service Engine Light on my 1998 Land Rover Discovery II came on at around 82,000 miles. I was told that is comes on around this time automatically for the oxygen sensor. I replaced the oxygen sensor, but do not know how to turn off the light. Does anyone know how I can turn off the light without having to take it to a Dealer and spend $90?

 

Some of the larger auto parts store chains (Like Autozone, Pep Boys, etc.) have a service for free, or for a nominal charge, where they will hook up a scanner for engine related codes, and then can clear it for you. But this is only for engine management related codes. Their scanners cannot read suspension or body electric component codes.


Please read my tech info pages at www.eurotekapg.com for tips and things to be aware of regarding your Land Rover

When the check engine light comes on it is for a fault code. If yourO2's needed to be changed, and at your mileage they are just about ready, you replace all 4 of them, not just one. The replacing of one is usually is one fails with low mileage on it, other wise you will have an imbalance of performance between engine banks. As has been mentioned some stores will clear codes for customers, some store however will not have a scanner that can do that function.

Out of Curiousity, how much do they run for? B/c I need to get them done as well..

 

The best prices right now that I am aware of are at Atlantic British where they are on sale or Rover Connection.
