Why do I have a faulty O2 sensor?
This is why when why people complain of below-average fuel economy, weaker than normal engine responsiveness, and overall performance, all of which point to a faulty front O2 sensor. The signal from the second bank of oxygen sensors is used primarily to detect any problems with the vehicle’s catalyst and to tune the fuel trim.
What’s the O2 sensor on a Harley Davidson?
P0132 o2 high, p0152 o2 high rear, p0134 o2 inactive front, p0154 o2 inactive rear, I have noticed my fuel economy has gone to heck, an average of 27mph.
Can a faulty sensor cause a catalyst to melt down?
As a result, the faulty sensor can cause, a too rich or too lean condition. Too rich and the catalyst can melt down. While, too lean and the converter is unable to convert the hydrocarbons into safe elements; and may not pass a state inspection.
Which is more expensive an O2 sensor or a wide band sensor?
Because of this, however, these wide-band O2 sensors are much more expensive than the traditional O2 sensors.
Can a bad oxygen sensor cause rough engine idle?
Rough Engine Idle. Vehicle engines that have a bad oxygen sensor often run irregularly or roughly. Oxygen sensors can control or contribute to many different engine functions, including fuel/air mixture, engine timing and engine combustion intervals. A faulty oxygen sensor can disrupt any of these things and cause a rough engine idle.
What happens if the OBDII sensor is not working?
If a failing or dead sensor is the issue, there are several OBDII codes in particular that will be set off (more on this in the following section). In turn, the vehicle itself will often display physical symptoms due to a sensor that is not functioning properly.
What happens if you have a bad O2 sensor?
If the fuel mixture has too much oxygen, the engine is burning lean. If the fuel mixture has too little oxygen, the engine is burning rich. In either case, the ECU needs this information in order to adjust the fuel/oxygen ratio. If your car has a defective o2 sensor, it will not run efficiently.
What do you do with O2 sensors on a Harley Davidson?
If you do not utilize your stock O2 sensors, you will need to use O2 eliminators. They snap onto your your harness where the O2 sensors were, previously, plugged in. Depending on what type of tuner you have; you may need to communicate to a tuner that the sensors are absent.
