How low does the voltage go? about 0.2 V
Average Voltage: 0.5 V
How many cross counts? 12
Q. If the signal is not cycling normally, describe what the signal does?
A. Cycling normally
Q. How high does the Oxygen sensor voltage go?
A. About 1.15 V
Q. If this signal is not going high normally, describe what the signal does?
A. It went high at once at the time of high acceleration of the engine and the but that when we let it free, the signal stayed average about 0.7 V for two seconds.
Q. How high does the Oxygen sensor voltage go?
A. About 1.0 V
Q. If this signal is not going high normally, describe what the signal does?
A. It was normal when the engine was Idle. Once we accelerate the engine, the voltage dramatically dropped down close to zero volt or we can say close to 0.1 V and stayed there for few second, about two seconds, before jumping up to.
Q. How long the sensor took to go from lean to rich?
A. About 0.1s
Discuss how a normal Zirconium Oxygen sensor works: draw a picture below to help show how it works?
Q. Discuss how good or bad this Oxygen sensor is. what about it functions well or is faulty? Use detail and specific voltage in your discussion. Can it accutely tell the ECU how rich or lean the exhaust is?
A. This is a good oxygen sensor. Oxygen sensor works well. It shows normal signal on oscilloscope . The voltage goes from about 0.15 V to 0.95 V in a cycle.
Yes it accurately tells the ECU about the rich and lean condition of exhaust gas.
