Just recently I have had a couple of members experiencing a CEL engine light triggered by the exhaust sensors. In both cases this has been diagnosesd as failing catalysts, but the same can be triggered by a faulty MAF or oxygen sensor failure. Both were on 2006 cars.
In one case the catalysts and associated components were replaced at a substantial cost. It still took some time and hunting around to eliminate the CEL.
In the second case, since the emissions tested within limits, a work around was found to stop the CEL coming on
The point of this thread is to ask if others have had this problem and, if so, could you let me know the diagnosis and solution.
Many thanks, John
