2001 Maxima SE Oxygen Sensor locations?

I can see three sensors - two are under the car and next to the catalytic converter. I also see one on the front part of the motor near the belts, but cannot find the other one?

Can someone help?

In the exhaust pipes before the catalytic converters. the sensors after the cats are cat monitors, they are not O2 sensors.

2004 Acura TL O2 sensor block 1 sensor 1 location


Proper terminology is Air/Fuel Ratio (A/F) Sensor Bank 1, Sensor 1. It's not an Oxygen sensor, per se. It is a wide range oxygen sensor. It is located in the top of the Bank one Catalytic converter which is at the firewall or windshield bank of the engine. There is no exhaust manifold. The cat converter bolts directly to the head. The A/F sensors screw into tops of the converters.

See a visual diagram of heat oxygen sensor bank 1 sensor 2 for ford taurus 2001


bank 1 exhaust is the rear manifold towards the windshield side. Follow the exhaust down. There should be one oxygen sensor before the catalytic converter and a monitor after the catalytic converter. Be Careful.. they look the same.

2001 Nissan Sentra. Car starts with no power, but after a few restarts, gain power again. Code is PO420.


Hi, P0420 code means a catalytic converter fault.
The catalytic converter has an oxygen sensor in front and behind it. When the vehicle is warm and running in closed loop mode, the upstream oxygen sensor waveform reading should fluctuate. The downstream O2 sensor reading should be fairly steady. Typically the P0420 code triggers the Check Engine Light if the readings of the two sensors are similar. This is indicative of (among other things) a converter that is not working as efficiently as it should be (according to specs). It is part of the vehicle emissions system.
  • Check for exhaust leaks at the manifold, pipes, catalytic converter. Repair as required.
  • Use a scope to diagnose the oxygen sensor operation (Tip: The oxygen sensor in front of the catalytic converter normally has a fluctuating waveform. The waveform of the sensor behind the converter should be more steady).
  • Inspect the downstream heated oxygen sensor (HO2), replace if necessary
  • Replace the catalytic converter

Where is the oxygen sensor locate


Which ones?

ALL O2 Sensors are in the exhaust converters or
in the pipe before, on an older vehicle

Some vehicles have them in the manifold

You have 2 for each pipe with a converter

The front ones,closest to the engine get replaced

WHERE IS THE OXYGEN CENSOR ON A 1997 GRAND MARQUIS


O2 sensors are located in the exhaust manifold near the Catalytic converter.
Some cars have the 02 sensor before the catalytic converter, some behind, and some before and after.

Simply locate the "bung" that contains the O2 sensor, and you will see the sensor connected to wires.
This is the best way to locate them.

I am trying to find where the co2 sensor is on my 2001 town&country van


Find the exhaust pipe under the rear bumper. Follow its progress towards the front of the car. The first big bulbous thing you will find is the muffler, keep going. The next bulbous thing you may find is a resonator, keep going. Eventually you will come to a little thingy screwed into the side of the exhaust pipe which has some wires coming from it. That is your downstream O2 sensor. Next will be the catalytic converter, next thing will be the upstream O2 sensor, then the exhaust manifold, the the head of the engine.

Po420 code monte carlo ls 2001


PO420 code is for catalyst system efficiency below threshold (bank 1) Usually it means that it is time for a new catalytic converter on bank number 1. Cylinder bank number 1 is always the bank with the number 1 spark plug in it.
