Suzuki Grand Vitara Oxygen Sensor

Culprits behind Suzuki Grand Vitara Oxygen Sensor Problems

The oxygen sensor on your Suzuki Grand Vitara detects if the engine's air to fuel mixture is running too rich, too lean, or just right. It may be ignored by most drivers, but this device can impact your engine's performance. In fact, failing to take care of the oxygen sensor can lead to poor gas mileage and increased vehicle emissions. So, if you suspect your auto to have a broken oxygen sensor, then better perform some troubleshooting. Listed here are just some of the common problems encountered with Suzuki Grand Vitara oxygen sensors and the reasons behind them.

Sudden decrease in gas mileage

An easy way to tell if the oxygen sensor equipped on your vehicle is defective is by checking for poor gas mileage. Poor gas mileage is caused by a miscalculation of the oxygen sensor. You see, a damaged oxygen sensor may lead to too much fuel addition to the air to fuel ratio. This imbalance will, in turn, result to poor gas mileage.

Increase in vehicle emissions

A faulty oxygen sensor may lead to an increase in your auto's fuel emissions. This is because the part will fail to adjust the engine's air to fuel mixture, which will likely cause inefficient engine combustion. When this happens, you may have to deal not only with mechanical problems but also legal problems.

Engine hesitation

Defective oxygen sensors may manifest through engine hesitation, which can be noticed when accelerating. For diagnosis, simply observe your Suzuki Grand Vitara if it stumbles or hesitates. This defect is also caused by a misinterpretation of the air to fuel mixture.

Engine misfiring

A damaged oxygen sensor can also lead to engine misfiring, which is easier to diagnose when the engine is idling.

Grease in oxygen sensor wire

Another reason for the oxygen sensor to malfunction is a greasy connection. A defective oxygen sensor may exhibit signs of bare wirings and damaged connections. In fact, these defective wires may even cause fire if the sensor is near the exhaust pipe. You can help prevent unnecessary accidents by replacing the oxygen sensor right after you diagnose a defect.

  • Tips to Keep Your Suzuki Grand Vitara Oxygen Sensor in Optimum Condition 27 February 2013

    Keeping your Suzuki Grand Vitara's oxygen sensor in its best condition is crucial if you want your car to retain an efficient gas mileage, and prevent an increase in vehicle emissions. Sometimes, even if the oxygen sensor is built to withstand wear and tear, you might soon find defects that can lead to detrimental changes in your exhaust system. If you have no idea how to take care of your Suzuki Grand Vitara oxygen sensor, then you are in luck. Listed below are just some of the maintenance procedures you may perform on an aging oxygen sensor:


    Check for signs of visual damage.


    Some defects on an oxygen sensor cannot be addressed by cleaning the part. Sometimes, replacement is your only option. So, if you find if that there are visual damages on the oxygen sensor, then you might have to spend some bucks and buy a new one. In this case, repair will not be able to restore the part's original functionality.


    Replace your oxygen sensor at a specific mileage point.


    To keep your engine performance in its best condition, it is advised that you replace the oxygen sensors at a specific mileage point. In general, oxygen sensors with one or two wires should be replaced every 50,000 to 60,000 miles. Oxygen sensors with three wires can be replaced for a longer time. They are ideally replaced after about 100,000 miles.


    Clean the oxygen sensor in a container full of gasoline.


    Preventing excess fuel consumption is easy if you perform constant cleaning on your car's oxygen sensors. In fact, performing this procedure can greatly aid in maintaining a top-notch engine performance. To perform cleaning, detach the oxygen sensor first by removing the connecting screws. Once this is done, place the oxygen sensor in a container full of gasoline and wait overnight. For optimum gains, shake the container at least a few times after an hour has passed. After a night of soaking the oxygen sensor, remove it and allow it to dry thoroughly. You can help dry the part by wiping with a paper towel. This should help improve fuel mileage.
