The Acura MDX has multiple oxygen sensors, but the exact number depends on the vehicle configuration and model year. The most important one is the upstream oxygen sensor, which is usually located in the exhaust manifold and helps maintain the proper air-to-fuel ratio in the combustion chambers for maximum fuel efficiency.

What symptoms does a bad O2 sensor cause?
First, what are the signs an O2 sensor may have gone bad?
- Check Engine Light Comes On.
- Noticeable Loss of Fuel Efficiency.
- Sulfur or ‘Rotten Egg’ smell from Exhaust.
- Black smoke from exhaust.
- Emission levels reach high levels.
- Your engine hesitates, skips, begins bucking or has power surges.
How much does it cost to replace all 4 O2 sensors?
The average cost for an Oxygen Sensor Replacement is between $362 and $412. Labor costs are estimated between $63 and $79 while parts are priced between $300 and $333. This range does not include taxes and fees, and does not factor in your unique location. Related repairs may also be needed.
How many O2 sensors does a v6 have?
Two of the four oxygen sensors are usually located in the exhaust manifold or upstream of the exhaust pipe. These two sensors monitor the exhaust at the front of the cylinder bank. The other two sensors are located downstream of the exhaust pipe, close to the three-way catalytic converter.
What would cause all 4 O2 sensors to go bad?
Why do O2 sensors fail? Since the oxygen sensor is in the exhaust stream, it can become contaminated. Common sources of contamination include an excessively rich fuel mixture condition or oil blow-by in an older engine and engine coolant being burnt in the combustion chamber as a result of an engine gasket leak.
How many O2 sensors do I have?
Modern vehicles with V-6 or V-8 engines could have as many as four O2 sensors — one located in each cylinder bank and one after each catalytic converter. If either the oxygen sensor in the cylinder block or the one for the catalytic converter fails, your vehicle could experience serious engine problems.
How much does it cost to replace the oxygen sensor on a 2016 Acura MDX?
The average cost for an Acura MDX Oxygen Sensor Replacement is between $579 and $615. Labor costs are estimated between $50 and $64 while parts are priced between $529 and $552. This range does not include taxes and fees, and does not factor in your unique location.
Where is the O2 sensor Acura MDX?
We’re going to use an offset 22 millimeter or 7 8 oxygen sensor put that into position. We’re also going to use is a swivel on a few extensions and a breaker. Bar. All right now that it’s broke free.
Can I drive with a failing O2 sensor?
Can I Drive My Car With A Bad Oxygen Sensor? We recommend against driving with a bad O2 sensor as the powertrain is not running on the correct fuel mixture. While it may perform fine in the beginning, if your engine is running rich and using too much fuel it might begin to clog the catalytic converter.
Do you have to replace both O2 sensors at the same time?
Manufacturers recommend replacing O2 sensors in pairs (both Upstream or both Downstream). An older, slower sensor can cause an imbalance in the engine management system, leading to poor fuel economy and possible damage to the catalytic converter.
Should I replace all 4 O2 sensors at once?
Do I need to replace all of the sensors at once? It is best to replace O2 sensors in pairs. For example, if you replace the downstream left sensor, you should also replace the downstream right.
