Question

2010 Nissan Rogue 2.5L. Replaced converter, service light still on. Told by the mechanic need to replace a 2nd converter?

Answer 1

Hi there,

The converter that causes this code is the converter right off the exhaust manifold. If this wasn't the converter that was replaced, then yes, you need to replace it. If it was, then it's likely there is a problem with the rear O2 sensor
