Shop Volvo S40 Replacement Oxygen Sensor

Luxurious sedans such as the nicely made Volvo S40 were intended to be handled gently and then given needed maintenance. To keep the luxury and comfort you chose with your Volvo S40, it's key to install only the best names in OEM and upgrade car parts. Would it be smart to budget a large sum for a nice comfortable luxury vehicle, only to skimp on new parts and accessories? Volvo boasts a reputation for striking looks that consistently turns heads, and the look is matched by fuel-efficient power. For drivers who give necessary emphasis on long lasting service life and quality engineering, Volvo is the vehicle of choice. That Volvo in the garage was manufactured with care and craftsmanship; it needs new OEM components with the same top level of value. Superb engine power and engine performance are derived from outstanding components and accessories. People who thrill over performance vehicles recognize that there's nothing more vital than installing the most outstanding replacement parts and accessories. A properly installed Volvo S40 Oxygen Sensor monitors how much oxygen that is funneled into your vehicle's engine cylinders. When your vehicle's ratio of fuel to air is inadequate, poor engine function will be observed; at the same time, a too-rich ratio leads to damage to your engine and unwanted pollution from your car's tail pipe. Located near the exhaust manifold, your car's Volvo S40 Oxygen Sensor reports oxygen levels measured in the car or truck's fuel to the engine computer. You no longer have to choose between your bankroll and value when you get aftermarket parts. Each Volvo already makes a statement ... make it an unforgettable one with our selection of quality accessories. Whether you drive a sporty coupe or a hard working truck, we have all the aftermarket parts you want here at www.partsgeek.com.

Research on Oxygen Sensor for Volvo S40

The oxygen sensor is a particular electronic device whose function is to measure the proportion of oxygen present in a liquid or gas. The original oxygen sensors were very expensive, so a modernized and cheaper version was developed in 1990 by a company called NTK. This oxygen sensor was used in Honda Civic and Honda Accord. The cars manufactured after 1980 feature this oxygen sensor. This measuring instrument is located in the emissions control system of any car. The oxygen sensor monitors the car emissions and sends emission data to the computer control system in the engine. Whenever the emission is excessive, this gadget alerts the computer control. This can be handy in states where vehicles are routinely inspected for emission checks.

The Volvo S40 oxygen sensor location monitors and measures the amount of oxygen funneled into the engine cylinders. When the fuel to air ratio is too high, that will cause damage to the car's engine. As a Volvo S40 owner, if you are concerned about preserving the long service life that this auto maker stands for, then you will ensure you always have a top performing oxygen sensor installed in your car.

Identified Volvo S40 Oxygen Sensor Problems

A malfunctioning oxygen sensor will lead to a failed emissions test. Oxygen sensors installed in Volvo S40 usually malfunction when they are contaminated with oil, coolant, or silicone. So a common oxygen sensor symptom may be a fuel leakage in the air intake or exhaust manifold, causing the senor to give erroneous alerts. So in case there is an observed fuel leak in your car, identify the source of the leak first before replacing the oxygen sensor. In such cases, repairing the leak will resolve the problem. The part replacement may not be necessary in such a condition. If there is any fluid leakage in the emission control system, then even after a parts replacement, the oxygen sensor will continue to fail. In cars manufactured in or after 1996, a cheap oxygen sensor will create problems in the emission system. In those cars, a quality oxygen sensor is required, even if that means paying extra.

The Usual Replacement Cost of Volvo S40 Oxygen Sensor

As per the nation-wide cost estimates, the average cost for replacing an Oxygen Sensor is estimated to be between $242 and $329. This cost estimate includes labor charges, which can be anywhere between $44 and $56, and parts price ranging from $198 to $273. This cost estimate does not include applicable taxes.

Exact match to OEM part. Replaced original oxygen sensor with the Bosch replacement. Cleared the P0402 code and have driven for a few days without the code reappearing. Much cheaper than any other auto part store. - 2005 Volvo S40 Oxygen Sensor - Upstream
