I would try oxygen sensor but you need to put it on the machine which will tell you for sure. good luck

The only fix is to replace it. If you are mechanicly inclined, this is a doable deal. Before you replace the sensor you should check the wiring for resistance you can use a volt/ohms meter (vom) and test the continuity of the wiring to the sensor.

You can test the engine coolant sensor by using an ohmmeter. Attach the positive and negative probes to the terminals of the coolant sensor.

Check for exhaust leaks, test oxygen sensor operation, replace the catalytic converter.Check for exhaust leaks, test oxygen sensor operation, replace the catalytic converter.

There really isn't any way to test the oxygen sensor to see if it is good or bad. If your check engine light is on you can take it to Autozone and they will hook it up to computer and if the oxygen sensor is bad, the computer will detect it.

You need to pull the code. Don't take a chance.

o2 sensor My list shows P1167 Invalid Test,throttle not depressed

No. Check the battery first. Then test for spark, fuel pressure, and test your coils.

Yes, along with dozens of other things.

In hospital premises It may be ABG Analysis (arterial blood gas). Blood wil take from the superficial artery and does the test. Another way is by SPo2 sensor machines, that is saturation point of oxygen sensor machines.

Many auto parts retailers can test it for you if you remove it and take it in.

Do a compression test to determine condition of engine internals

obd2 means on board diagnostics failed not o2 sensor, 1st have to figure out why obd2 failed.

Reassure the resistor of the hot wire anenmeter to determine if it has failed. This can be done at the same time that you test the oxygen sensor.

oxygen sensor is basically a thermocouple. its voltage will vary with the oxygen content in the exhaust stream and must be heated to its operating temperature in order for it to work. most new sensors are of the heated variety so they will work sooner and at idle when the older versions won't. if your sensor is lazy, nothing you can do for it but replace it. sensors can be destroyed by leaded fuels, silica contamination and such or someone trying to test one without proper test equipment.

Bank 1 is the upper oxygen sensor(s) before the catalyst (catalytic converter) bank 2 is the oxygen sensor after the catalyst (catalytic converter)

I just ran a diagnostic test on my 1993 Towncar yesterday and got the codes 172 (oxygen sensor), 175 (oxygen sensor, 176 (oxygen sensor), 181 (rich), 189 (rich) and 332 ( gas resonator flow detected if that help you any.

theres no good test for this. but heres a few symtoms of a bad 02 sensor. engine will run real rough, engine pinging, bad fuel milage, and increased vehicle emissions. The defective oxygen sensor also shows up as a check engine light or malfunction indicator lamp illuminating in the vehicle's dash board.

My 94 Mazda v6 323f feels like its going to die if i press the accelerator fast, but if i build up the revs slowly, it is smooth. The idle is smooth too. Is this an O2 sensor problem or another? How do I test if the sensor is faulty or not?

most modern lambda sensors have a heating element and relay which can drain the battery. To test, disconnect the sensor ,if found to be the cause buy new lambda sensor and check wiring.

Codes 21- (A). Oxygen sensor stays at center neither rich or lean signal is detected from oxygen sensor input. OR (B). oxygen sensor shorted to voltage, oxygen sensor voltage maintained above normal range(1990 and later models. 32-(A). EGR solenoid circuit-an open or shorted condition detected in the EGR solenoid (some California models) Or (B) EGR system failure- Required change air/fuel ratio not dected during diagnostic test(some California models) And lastly 55-N/A Completionof fault code display on the CHECK ENGINE light

Have a qualified test the oxygen sensor on a lab scope the information from the signal should tell them whether the vehicle is in proper fuel control.this info should help them to correct your emmision failure.

Bad rings? Bad valve? Do a compression test Bad head gasker? Lazy oxygen sensor?

Check for exhaust leaks, test oxygen sensor operation, replace the catalytic converter.
