According to the search results, the 2005 Acura TL has two oxygen (O2) sensors. One is located upstream, before the catalytic converter, and the other is located downstream, after the catalytic converter.

Should I replace both O2 sensors?
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.
How much does it cost to replace the oxygen sensor on a Acura TL?
between $356 and $431
The average cost for an Acura TL Oxygen Sensor Replacement is between $356 and $431. Labor costs are estimated between $52 and $66 while parts are priced between $304 and $365. This range does not include taxes and fees, and does not factor in your unique location.
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.
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.
How many O2 sensors does a v6 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.
Will an O2 sensor work without a catalytic converter?
an O2 sensor does not need a cat to function properly. There are aftermarket fuel injection systems that use an O2sensors to keep fuel mixture anywhere you want, usually way richer then is safe with a cat. The sensor just reports free oxygen, the software it reports to does whatever it’s written to do.
How many O2 sensors do you have?
Most cars have at least two oxygen sensors located throughout the exhaust system; at least one in front of the catalytic converter and one or more downstream from the catalytic converter. The “pre-cat sensor” regulates fuel supply, while the downstream sensor measures the efficiency of the catalytic converter.
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.
Are oxygen sensor 1 and 2 the same?
What is Sensor 1 & 2? The sensor number is telling us where on the exhaust system the O2 sensor or Exhaust temperature sensor is mounted. The 1st sensor is located closest to the engine and the last is located at the rear of the exhaust system.
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.
