OEM Mopar Oxygen Sensors

Ever looked at your vehicle's exhaust system? You may have noticed it has parts that look like spark plugs. They're oxygen sensors. They figure out whether the system's oxygen levels are right so your engine can determine how much fuel it should use. Unfortunately, though newer oxygen sensors can last as many as 100,000 miles, failure is common. It's usually the fault of sensors that've gotten dirty, often because of motor oil or fuel. When to replace an oxygen sensor, then, is straightforward: when problems with them appear.

What are the Signs of a Bad Oxygen Sensor?

Look for a lit Check Engine light and worsening fuel efficiency, mainly. The latter suggests your engine may be consuming too much gas, suggesting it isn't getting the feedback it needs from the sensor. If you're still having troubles with your oxygen sensors, take a look at your vacuum hose first. It may just require a reconnection. Otherwise, check all the sensors you've got. Your vehicle can have two to four. Some models have one on each exhaust manifold. Others may have one just after their catalytic converters. To be sure they're the problem, get an inspection or run one yourself: plug in a code reader. If any need changing, it's easy. Simply unscrew the old ones and screw in the new.
