DENSO Auto Parts Oxygen Sensor P/N:234-4840
DENSO Auto Parts 234-4635 oxygen sensor for the 1999-2000 Jeep Grand Cherokee V8 4.7L reads the oxygen in the exhaust so the engine computer can adjust fuel delivery. Built and tested to OE standards, it is made for an exact, first-time fit.
A worn oxygen sensor can show up as a check engine light, a rough idle or poorer fuel economy. These signs alone do not prove the sensor is the problem, since a vacuum leak can also upset the idle.
This is a direct-fit replacement for the 1999-2000 Jeep Grand Cherokee V8 4.7L, which takes one upstream sensor. This listing is one sensor.
