The job of an oxygen sensor in a vehicle is to compare the oxygen content coming out of the exhaust to the oxygen content in the exhaust stream. This helps the vehicle computer determine whether to enrich or lean the fuel mixture, allowing the catalytic converter to operate more efficiently and reduce emissions into the environment. Exhaust byproducts can often block the sensor’s element over time causing poor fuel economy and increased emissions.

Drivers of certain newer model Dodge Ram trucks and SUVs have been experiencing problems related to their vehicles emissions system. Owners complaints include pinging engine noises when the vehicle is under load, increased smoke from the tailpipe, intermittent check engine light, engine power loss, and increased fuel consumption. All these problems seem to point to O2 sensors according to diagnostics run on the vehicles. (Diagnostics Codes Include: Crankcase Ventilation System Disconnected, Diesel Particulate Filter Regeneration Frequency, Diesel Particulate Filter Restriction Ash Accumulation, Oxides of Nitrogen Exceeded.)

Complaints of repeated repair attempts on these Doge Ram truck emission systems are causing consumers to question the integrity of the system. This O2 sensor problem has been experienced with older and newer model Dodge vehicles in which a regular maintenance schedule has been closely followed, as well as with vehicles newly driven off the lot.
