New Dodge vehicles are powerful, a lot of them
equipped with large engines that can produce large amount of torque and
horsepower. But despite this, new Dodge vehicles are very fuel
efficient. They are also safe for the environment as they do not emit a
lot of harmful combustion byproducts. These characteristics, however,
are expected to change as the vehicle grows older. When the Dodge
oxygen sensors start to deteriorate, you can expect the vehicle’s fuel
consumption and emission levels to start rising.
But what is an oxygen sensor and how can it help control the emission
levels and fuel consumption of Dodge vehicles? An oxygen sensor is a
small electronic sensor inserted in the exhaust system of your Dodge to
measure the amount of oxygen remaining in the exhaust gas. There are
many types of oxygen sensors. Among the more popular varieties is the
heated thimble, unheated thimble, planar, wide-band, and titania. All
except the titania oxygen sensor makes use of a zirconia ceramic
element for the sensor element.
Dodge oxygen sensors help control the emission levels and fuel
consumption of vehicles by providing the engine management computer
with the data it needs to control the fuel injection system. The sensor
element in O2 sensors create voltage signals or change its resistance
when the air to fuel mixture is rich (less than 14.7:1). This voltage
signal or change in resistance is constantly being monitored by the
engine management computer, which in turn would adjust the mixture of
air and fuel being fed to the engine so as to achieve the best possible
fuel economy and the lowest possible exhaust emissions.
Dodge oxygen sensors are designed to do their functions well.
Unluckily, oxygen sensors are not meant to last for a long time.
Contamination with phosphorus from excessive oil consumption, silicone
from internal coolant leaks, silicon sealants that are used in the
engine and some over-the-counter fuel additives may cause the oxygen
sensor to fail prematurely. And even if your Dodge oxygen sensor is
well protected or designed to outlast these hazards, automotive
maintenance experts would still recommend that the sensors be replaced
periodically as indicated in your vehicle manual.
