If the oxygen sensor isn't working properly, the exhaust gasses can't be properly regulated. When the exhaust emissions measured by the emission analyzer are too high, the 2010 Honda CR-V fails the emissions test. One of the prime reasons for this could be a faulty oxygen sensor.
Oct 29, 2022 · I have a faulty O2 sensor, but i'm not sure also, if previously ordered the good one for upstream and downstream. Is there a difference between them? There was a simular thread but could not figure it out at the end if both are the same.
Apr 26, 2022 · The O2 sensor lets the computer know if the fuel mix is burning rich (not enough oxygen) or lean (too much oxygen). Knowing the ratio of fuel to air allows your vehicle’s engine to make any...

Upstream O2 sensors are important for engine performance
There are multiple O2 sensors in Honda CR-V, how many depends on vehicle configuration and model year. But the most important one is the upstream O2 sensor, the one that is closest to the engine, usually in the exhaust manifold. The upstream O2 sensor helps in maintaining proper air to fuel ratio in the combustion chambers for maximum fuel efficiency and engine performance. Any fault in this sensor can cause all sorts of performance issues in your CR-V.
Downstream O2 sensors do not affect engine performance
The downstream O2 sensor in CR-V is located further down the exhaust system, after the catalytic converter, and is responsible for measuring the level of pollutants passing through the catalytic converter. The main purpose of downstream O2 sensor is to ensure that the catalytic converter is functioning properly. If this sensor goes bad, it does not have any affect on the engine performance, but the check engine light may illuminate and you may see error codes related to catalyst efficiency.
Faulty oxygen sensors are the leading cause of premature catalytic converter failures. If you suspect a problem with O2 sensor in your CR-V, you should act immediately and get it checked by a professional mechanic. Because O2 sensors are relatively cheap compared to the price of catalytic converters, which can easily cost you over a thousand dollar...
If there is any fault in the oxygen sensor, it usually illuminates the engine check light in the instrument cluster of Honda CR-V. You can diagnose the problem by connecting an OBD2 scanner to your vehicle. If you see any error code from P0130 to P0135 or from P0150 to P0155, it indicates a problem with the upstream oxygen sensor. You can also perf...
You don’t necessarily have to visit a workshop to replace oxygen sensor in your Honda CR-V. All you need is a wrench for this replacement job. Make sure the engine is cold before replacing the sensor to prevent burn injury. 1. Locate the O2 sensor to be changed. 2. Unplug the connector of the sensor. 3. Unscrew the O2 sensor with a wrench. 4. Apply...
All O2 sensors fail over time since it is a wearing part. There is no fixed time limit for when they fail, but they typically last over 100,000 miles in CR-V. However, they can fail much sooner due to contamination. For example, due to silicates entering the exhaust system after coolant burns in the engine due to a leaky head gasket, or phosphorus ...
Driving your Honda CR-V with a bad O2 sensor can cause sluggish and rough acceleration, along with high fuel consumption and emissions. And if you continue driving for several months, it may lead to engine damage or catalytic converter failure which can cost thousands of dollars to fix or replace.
If the oxygen sensor goes bad in CR-V, it does not send correct measured values to the engine control unit. The optimal amount of fuel can no longer be calculated which results in either too little or too much fuel injected into the combustion chambers. The engine runs too “lean” or too “rich”. Since a rich or lean condition robs a vehicle of pow...
A faulty O2 sensor can certainly cause shaking or vibrations in Honda CR-V when driving. When the O2 sensor goes bad, it causes improper air-to-fuel mixture in the combustion chambers which can cause the engine to shake, these vibrations can be felt in the cabin of the vehicle when driving.
According to EPA, replacing a bad oxygen sensor can improve fuel economy by as much as 40 percent. So if your CR-V develops a greater thirst for gas, you should definitely consider checking or replacing O2 sensor, especially if the vehicle has racked up more than 100,000 miles.
Since Honda CR-V is equipped with on-board diagnostics (OBD), a fault diagnosis can provide initial indications of where the malfunction is located. To begin troubleshooting, you must first connect the diagnostic tool to your CR-V. The OBDII connector is usually located under the dashboard. With the tool connected, turn on the ignition. Most diagno...
May 31, 2019 · If you spot any of these issues, it’s a strong indication that your Honda CR-V’s oxygen sensor is faulty or failing and should be replaced. However, if the sensor appears to be in good condition, you may want to seek professional help for further diagnosis.
Nov 26, 2018 · The pre-O2 sensor different than the post-O2, or at at least the ECU is looking for different readings to make sure the cat is doing it's job. When it's not, it sets the P0420 code for Catalyst Efficiency below Threshold.
