four
The 5.0 liter V8 has ( 4 ) oxygen sensors The 4.0 liter EFI ( which is an over head valve / pushrod design ) has ( 3 ) oxygen sensors Note: The 2 upstream oxygen sensors are used for adjusting the air / fuel ratio of the engine , the other oxygen sensor (s) are called catalyst monitors and monitor the performance of the catalytic converter(s)

In 2004, the Dodge Cummins Diesel was not equipped with an oxygen sensor. The 2007.5 and newer Cummins 6.7 liter Bluetec diesels have an O2 sensor in the downpipe. Typically, only particulate filter equipped diesels have O2 sensors.
