How many o2 sensors does a 2011 chevy equinox have?

The 2.4L four-cylinder and 3.4L V6 engines have two oxygen sensors, one in the rear exhaust manifold and one in the exhaust pipe after the catalytic converter. The 3.0L and 3.6L V6 have four oxygen sensors, one in each exhaust manifold, and one just after each catalytic converter.

How many 02 sensors does a 2011 Chevy Equinox?

You have 2 oxygen sensors in your Chevrolet Equinox. One located before the catalyst and one after. If you’re having any issues with these components, feel free to contact YourMechanic, as a certified technician can help you diagnose and replace these oxygen sensors if necessary.

What causes code P0138?

What the P0138 code means. P0138 is the OBD-II generic code indicating the O2 sensor for bank 1 sensor 2 fails to have a lower voltage output below 1.2 volts for more than 10 seconds indicating a lack of oxygen in the exhaust stream.

Is it best to replace O2 sensors in pairs?

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. However, on most vehicles produced since 1996, replacing one sensor (especially the front engine monitoring sensor) will cause the ECU to set a code for the other sensors.

How do I know if my upstream or downstream O2 sensor is bad?

Here are some of the most common signs that your oxygen sensor is bad.

  1. A Glowing Check Engine Light. The bright orange Check Engine light in your dashboard will usually glow if you have a bad oxygen sensor. …
  2. Bad Gas Mileage. …
  3. An Engine That Sounds Rough. …
  4. An Emissions Test Failure. …
  5. An Older Vehicle.

Should I replace upstream and downstream O2 sensors at the same time?

Buying all four is a waste of money since the two downstream sensors rarely fail and pretty much never wear out. Those two are only used to monitor the converters and don’t have any bearing on the engine’s operation. Worst case, replace the two upstream sensors if you wish.

How many O2 sensors does a V6 have?

Therefore, while most vehicles have two oxygen sensors, those V6 and V8 engines equipped with dual exhaust have four oxygen sensors — one upstream and downstream of the catalytic converter on each bank of the engine.

Can you clean an O2 sensor?

There are no true oxygen sensor cleaners that are safe to put through your engine. While some people choose to remove them and use a wire brush or an aerosol cleaner to remove deposits, we do not recommend trying to clean O2 sensors.

Are bank 1 and bank 2 O2 sensors the same?

Bank 2 Sensor 1 is the first sensor closest to the engine. On Bank 2 means it is at the engine side with cylinders 2, 4, 6, 8, etc. Bank 2 Sensor 2 is the second sensor on the engine’s exhaust pipe, usually behind the catalytic converter.

Are both oxygen sensors the same?

Physically, there’s no difference between front and back O2 sensors. They function in the same way, but the vehicle’s computer uses the measurements that they take for different purposes.

Can I use any oxygen sensor?

Unless the actual part number on the sensor is a direct and listed (published) catalog interchange for your year, make and model, the sensor will not work as intended. The other issue is unless the sensor is really old, it should be tested prior to condemning it.
