Q: How many Oxygen Sensors? 2002 Chrysler 300M

asked by on

How many O2 sensors does a 2002 Chrysler 300M have?

Hello - there are 4 oxygen sensors, one before, and one after each catalytic converter. Since you have a dual exhaust system, there are 2 catalytic converters in the exhaust system. Hence, 4 total sensors in total. For assistance with replacements, I recommend an oxygen sensor replacement performed by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.
