O2 Sensor Voltage Chart
O2 Sensor Voltage Chart - After driving on the highway, my downstream o2 sensor voltage was a steady 0.8v, which is high. There are numerous lambda calculators online. From what i’ve researched, downstream o2 sensors can still vary between 0 and 1 volts but will not oscillate rapidly. First graph is up stream o2 sensor voltage, second is down stream o2 sensor voltage, while the third is the up stream sensor short term fuel trim (stft). The following image clarifies my question. Instead the changes in voltage will be pretty smooth. Does this mean i have a bad catalytic converter, or is there another explanation?
To verify the wiring, i plugged the b1s2 harness into the b2s2 o2 sensor and it worked plugged into the other side of the car. The ecm detects a low voltage in the o2 bank 1 sensor 3 circuit. On the other hand, when idling before the drive, it was a steady 0.3v. Possible shorted or crossed wires.
To verify the wiring, i plugged the b1s2 harness into the b2s2 o2 sensor and it worked plugged into the other side of the car. Oxygen concentration is only one of the variables. After driving on the highway, my downstream o2 sensor voltage was a steady 0.8v, which is high. Does this mean i have a bad catalytic converter, or is there another explanation? The problem didn't move with the sensor. The following image clarifies my question.
Narrowband O2 Sensor Voltage Chart
I may be wrong, but i expect down stream sensor voltage to remain fairly steady, while the up stream should fluctuate instead. The following image clarifies my question. On the other hand, when idling before.

Does this mean i have a bad catalytic converter, or is there another explanation? No stft data is produced for down stream o2 sensor. The freeze frame data shows that the b1s2 oxygen sensor reads.
Bad O2 Sensor or Cat Problem? Maintenance/Repairs Car Talk Community
The problem didn't move with the sensor. Instead the changes in voltage will be pretty smooth. I still have the same problem. From what i’ve researched, downstream o2 sensors can still vary between 0 and.
DME Motronic O2 sensor questions Pelican Parts Forums
Oxygen sensors do not measure oxygen concentration, they work by switching from high to low voltage at the stoichiometric point. 2)every time there is a spike in the a/f voltage, the short term fuel trim.
P0430 Catalytic converter system, bank 2 efficiency below threshold
I may be wrong, but i expect down stream sensor voltage to remain fairly steady, while the up stream should fluctuate instead. The downstream o2 sensor voltage oscillates between 0.2 v and 0.8 v at.
Wideband O2 Sensor Voltage
This could cause the sensor voltage to be lower than expected. The o2 sensor bank 1 sensor 3 is downstream of the last catalyst in the exhaust system, so an exhaust leak before the sensor.
o2 sensor voltage LS1TECH
To verify the o2 sensor works, i switched the two downstream sensors. The o2 sensor for bank 2 sensor 2 is stuck in the lean voltage output when tested and stayed lean for a certain.
Wideband O2 Sensor Voltage Chart
So in my case, there is nothing to worry about and the downstream sensor is working correctly. To verify the wiring, i plugged the b1s2 harness into the b2s2 o2 sensor and it worked plugged.
The o2 sensor bank 1 sensor 3 is downstream of the last catalyst in the exhaust system, so an exhaust leak before the sensor can cause the code due to excessive oxygen getting into the exhaust stream. No stft data is produced for down stream o2 sensor. From what i’ve researched, downstream o2 sensors can still vary between 0 and 1 volts but will not oscillate rapidly. The problem didn't move with the sensor. So in my case, there is nothing to worry about and the downstream sensor is working correctly.
From what i’ve researched, downstream o2 sensors can still vary between 0 and 1 volts but will not oscillate rapidly. No stft data is produced for down stream o2 sensor. With the car stationary, engine warmed up, revving at about 1500 rpm i have captured this downstream o2 sensor voltage: The exhaust has a leak in front of the o2 sensor.
Oxygen Concentration Is Only One Of The Variables.
I still have the same problem. To verify the o2 sensor works, i switched the two downstream sensors. This could cause the sensor voltage to be lower than expected. The upstream o2 wideband sensor value (or rather its interpretation by the ecu) oscillates around 14.7.
Oxygen Sensors Do Not Measure Oxygen Concentration, They Work By Switching From High To Low Voltage At The Stoichiometric Point.
The o2 sensor for bank 2 sensor 2 is stuck in the lean voltage output when tested and stayed lean for a certain amount of time during ecm testing. The exhaust has a leak in front of the o2 sensor. On the other hand, when idling before the drive, it was a steady 0.3v. Does this mean i have a bad catalytic converter, or is there another explanation?
No Stft Data Is Produced For Down Stream O2 Sensor.
Possible shorted or crossed wires. The freeze frame data shows that the b1s2 oxygen sensor reads 0 volts. That is why it is not oscillating between 0 and 1 v. So in my case, there is nothing to worry about and the downstream sensor is working correctly.
Is It Normal For The Downstream O2 Sensor Voltage To Be So High After Driving?
It takes into account the mass balance of the constituents of the gasses in the exhaust from a combustion process. I may be wrong, but i expect down stream sensor voltage to remain fairly steady, while the up stream should fluctuate instead. From what i’ve researched, downstream o2 sensors can still vary between 0 and 1 volts but will not oscillate rapidly. First graph is up stream o2 sensor voltage, second is down stream o2 sensor voltage, while the third is the up stream sensor short term fuel trim (stft).
