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.
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.
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.
