Each sensor is a four-wire, screw-in type with a stainless steel housing and a black four-pin plug. Reference numbers include 234-4029 and 234-4030. Easy Life Markets sells the four sensors together, for owners who want to renew every sensor in one go.\u003c\/p\u003e\n\n\u003cp\u003eMost Wranglers in this range run four oxygen sensors: two ahead of the catalytic converters, which the engine computer uses to control fuelling, and two behind them, which watch how well the converters are working. They all age at about the same rate. When one sets a fault code, the others are usually not far behind, which is why many owners change the full set.
