Do you replace O2 sensors for the heck of it?
O2 sensors are not something you replace for the heck of it. Of course not, but for what the military calls high-rel, you will at a certain mileage. When I asked some time ago, those who understood the issue admitted that sensors start deteriorating at maybe 100,000 or 120,000. So, the first predictable failures will happen in that range.
How do you remove an oxygen sensor from a car?
Disconnect the electrical connection to the oxygen sensor. Follow the cable away from the end of the sensor plugged into the exhaust line. It will end in a plastic plug inserted into an outlet. To remove it, locate the small tab on the end of the plug. While pushing the tab down, pull the plug back by hand.
What does it mean to fake out an oxygen sensor?
“Faking out” an oxygen sensor refers to the process of bypassing the sensor so that the sensor does not relay the correct information to the system’s computer. This is especially useful if you are trying to manually override the air and fuel settings-also called “tuning” or if you are trying to run your vehicle without a catalytic converter.
Where are the O2 sensors on a V-6 engine?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
How do you replace the O2 sensor in a car?
Once you’ve replaced your vehicle’s O2 sensor, you’ll need to reset the ECU so it can properly gather information from the new O2 sensor. Open the fuse panel in the driver-side foot well, under the steering column, by pulling down on it with your fingers.
Where are the pins to replace the oxygen sensor?
Depending on your emissions rating which you will find under the hood on the label the pin configurations are different. On pins number three and four measure the resistance for the heater circuit. If it is not within spec replace the sensor.
When is it time to replace your oxygen sensor?
Oxygen sensors eventually need to be replaced in all vehicles. If your vehicle’s O2 sensor is faulty, chances are there will be signs! Check this list to see if it’s time to replace YOUR vehicle’s oxygen sensors: Sudden decrease in fuel mileage.
What kind of O2 sensor does pre99 have?
The pre99’s have the old 02 sensors which take much longer to kick in than the 99or newer trucks with the wideband or Air/Fuel ratio sensors, so your fine just look on the ODB reader to make sure the 02 sensor is properly swinging up and down but if you have no CEL Id look elsewhere.
O2 sensors are not something you replace for the heck of it. Of course not, but for what the military calls high-rel, you will at a certain mileage.

How long does it take for O2 sensor to warm up?
As said above, you shouldn’t note any difference in performance, old vs new, until the sensors warm up to operating temperature, which can take 5-10 minutes. If you do note some difference, post back. If the car simply won’t run well with the new sensors, it could still be , and indeed likely, that the new sensors are ok.
Why does my O2 sensor keep sputtering?
After a half hour of trying to get it working by doing this I decide to switch back to the old O2 sensors temporarily thinking I just got a bad new O2 sensor from the manufacturer. Only thing is after switch the old ones back on the car still sputtered like crazy for a while until it seemed to be running fine.
What’s the resistance of the Toyota O2 sensor?
I tested the new o2 sensors resistance as stated in the Toyota shop manual (it is supposed to read 11-16) and the front one read 16 and the rear read 21 so I think I may have gotten sent a bad rear O2 sensor. I have found buying cheap brand name stuff on Amazon to be a fool’s errand sometimes.
Why does my car not run with the new sensors?
If the car simply won’t run well with the new sensors, it could still be , and indeed likely, that the new sensors are ok. The cause would be that the ECM is now going into closed loop, and there’s something else wrong.
Why did Bank 1 sensor 1 open up?
I stopped at the first rest stop to put on the scanner, and found that Bank 1 Sensor 1 had an open heater. This makes sense, because any filament type device does most often open up the instant you turn on the power to it.
