What should the output voltage of a 1993 Subaru Imprezza oxygen sensor be?
Oxygen sensor voltages on a 1993 Subaru and most other vehicles should, with the sensor fully warmed (above 600 degrees F) vary rapidly above and below .45 volts. The range of fluctuations can be from .1volt to .9volts. A digital voltmeter will usually average these voltages to about .45 volt. Lower voltages indicate a lean mixture and higher voltages indicate a rich mixture. A scan tool or oscilloscope is necessary to see acurate live voltage changs on an oxygen sensor.
How do you know if an oxygen sensor needs changed?
If there is a high resistance across the heater circuit if the voltage fluctuations are lazy or not even ie. there should be one rich to lean voltage fluctuation for every 1.2 seconds and then sine wave should be nice and even
Should a knock sensor be replaced when an oxygen sensor is?
NO. there 2 different things / sensors.
Where is the heated oxygen sensor 1996 Ford Taurus?
The 1996 Ford Taurus heated oxygen sensor can be found behind the dashboard on the passenger side of the passenger compartment. The oxygen sensor should be labeled as such.
Where is oxygen sensor bank 1 sensor 2 on a 2000 Mazda MPV?
That should be the sensor after the catalytic converter.
How much voltage should a coolant temp sensor have?
2 to 3 volts.
How do you fix a P0107 code on a 1998 Jeep Wrangler 4.0?
That is a MAP sensor code, check to see if the sensor is returning at least .5 volts, if not check for 5 volt reference voltage on the connector. If you have voltage going in, and none or less coming back out replace the sensor, if no reference voltage check the connectors, wiggle them and monitor the voltage. If the wiggle test checks out, draw a vacuum on the MAP sensor vacuum port. As you add vacuum the voltage should decrease. With no vacuum, the MAP sensor should read around 4.5 volts. If there is no change in MAP sensor reading on the scan tool, replace MAP sensor.
How do you check a knock sensor?
remove the sensor, backprobe the plug with a multimeter set on voltage, tap the knock sensor lightly with a spanner, you should see voltage respond by increasing whenever you tap it, this means your knock sensor is working correctly. if it does not move however it means that the sensor is faulty.
What is the torque specification on a 2001 Toyota tundra front oxygen sensor?
The 2001 Toyota Tundra front oxygen sensor torque specification is 20 pounds. The oxygen sensor bolts should be torqued in 10 pound intervals.
What sensor is in the plastic intake manifold on a 1997 Buick le Sabre 3.8l?
That should be the Oxygen Sensor
Where is the oxygen sensor on a 2000 Saturn SC2?
There should be two Oxygen sensors; the one that wears out most frequently is installed in the exhaust manifold, close to where the exhaust pipe connects. The second Oxygen sensor should be behind the catalytic converter.
How many oxygen sensor does a 98 chevy SUV have?
Should be 2 of them.
