The 2007 Honda CRV has two oxygen sensors. One is located before the catalytic converter, known as the upstream or pre-cat sensor, and the other is located after the catalytic converter, known as the downstream or post-cat sensor.

How do I know how many O2 sensors I have?
How Many Oxygen Sensors Are There in My Car? Most cars will have several oxygen sensors. There will be one in front of the catalytic converter and one in every exhaust manifold. Modern vehicles usually have at least four oxygen sensors placed at key points in the exhaust system.
Should I replace both O2 sensors?
In this case, it is best to replace both corresponding sensors on each bank if you have a V6 or V8. For instance, if your bank 1 upstream sensor has gone bad, you should probably also replace your bank 2 upstream sensor. If you don’t, then it is likely that the bank 2 upstream sensor is going to go bad soon.
How many O2 sensors does a 2006 CRV have?
Well it depends on a crv if you look under your car from the drivers side to the area of the second row of seats you will see the catalytic converter. Connected in the cat you will see 2 sensors. They are about the size of spark plugs with wires coming out the back.
What symptoms does a bad O2 sensor cause?
Signs a Vehicle has a Bad O2 Sensor
- 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.
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.
How much does it cost to replace an O2 sensor on a Honda CRV?
The average cost for a Honda CR-V Oxygen Sensor Replacement is between $502 and $561. Labor costs are estimated between $35 and $45 while parts are priced between $467 and $516.
How do I know if it’s my catalytic converter or O2 sensor?
To check if it’s a clogged cat versus a bad oxygen sensor (when you don’t have a check engine light), grab a vacuum gauge. Connect the gauge to an intake manifold vacuum line. Start the engine, let it idle, and check the reading on the gauge. This is your baseline vacuum.
Do you need to replace both upstream and downstream 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 do I know which O2 sensor is bad?
What Are the Symptoms of Bad Oxygen Sensors?
- Oxygen Sensor: How it Works. Most oxygen sensors generate an electrical signal that tells your car’s Powertrain Control Module how much to alter the air-fuel mixture.
- Illuminated Check Engine Light.
- Poor Gas Mileage (Plus Bad Smells & Black Smoke)
- Poor Engine Performance.
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.
