How is P0137 diagnosed?

What Are the Symptoms of Code P0137?

1. Check Engine Light.
2. Possible exhaust leaks.
3. Exhaust odor.
4. Vehicle running rough.
5. Lack of power.

What does Bank 2 oxygen sensor do?

The Downstream Oxygen Sensor (Oxygen Sensor 2) Oxygen sensor 2 is the downstream oxygen sensor in relationship to the catalytic converter. It measures the air-fuel ratio coming out of the catalytic converter to ensure the catalytic converter is functioning properly.

Where is heated oxygen sensor located?

Heated Oxygen Sensors In closed-loop, the ECM relies on input from the O2 sensors and other sensors to calculate the air-fuel ratio. Oxygen sensors are located in the exhaust manifold or exhaust pipe of the engine’s exhaust system.

How many O2 sensors does a 2006 Acura MDX have?

Two sensors are located immediately upstream of both of the warm up three way catalytic converters, which are attached to the exhaust manifold on each bank of the engine. The remaining two 02 sensors are located in the exhaust stream immediately downstream of these two warm up three way catalytic converters.

How do I change the O2 sensor on my Acura MDX?

Procedure

1. Park your ACURA and open the hood.
2. Disconnect Negative Terminal.
3. Locate O2 Sensor.
4. Disconnect Sensor Press the connector and pull it away to unplug the oxygen sensor.
5. Place the oxygen sensor socket on the sensor and break it loose.
6. Install the new oxygen sensor.

Can you drive a car with a bad O2 sensor?

Can You Drive With A Bad Oxygen Sensor? Yes, you can drive with a bad oxygen sensor if you can still start your engine and feel little difficulty driving. But don’t leave it alone for over a couple of days, as it might cause safety problems and lead to the malfunction of other parts of your vehicle.

How much does it cost to replace O2 sensors?

A brand new replacement oxygen sensor can cost you from $20 to $100, depending on the make and year of your car. Taking your car to a mechanic to fix the issue can cost up to $200.

What causes the P0158 OBD-II trouble code?

What causes the P0158 code? 1 Failed rear oxygen sensor 2 Failed rear oxygen sensor heater circuit 3 Engine coolant temperature sensor bad 4 Shorts, breaks, or exposed oxygen sensor wiring 5 Excessive fuel pressure 6 Necessary power control module (PCM) update 7 Failure of the power control module (PCM)

How do you remove the oxygen sensor from an Acura?

Disconnect Sensor Press the connector and pull it away to unplug the oxygen sensor. Place the oxygen sensor socket on the sensor and break it loose. Removing the oxygen sensor on an old ACURA may be difficult at first due to rust. If the sensor doesn’t come off, spray penetrating oil near the threads and wait at least 15 minutes.

Where are the O2 sensors on an Acura MDX?

The upstream sensor is before the catalytic converter, and downstream is after the catalytic converter. Acuras that are equipped with the 3.5L engine have two catalytic converters and four O2 sensors.

How to check for an OBD-II trouble code?

A mechanic will use an OBD-II scanner to pull all present trouble codes that have been stored by the power control module (PCM). The live data for the oxygen sensor on the scanner is reviewed. They will check the voltage reading to see if the oxygen sensor switches from low voltage to high voltage every few seconds.

What causes a P0158 code on an O2 sensor?

Potential causes of an P0158 code include: Bad o2 sensor (Bank 2 Sensor 2) Wiring in contact with exhaust components Engine running rich (If other codes are present) Holes in exhaust causing PCM to over-rich engine resulting in an abnormally high Bank 2, sensor 2 reading Short to voltage on signal circuit Bad PCM

Where are the O2 sensors located on an Acura MDX?

The remaining two 02 sensors are located in the exhaust stream immediately downstream of these two warm up three way catalytic converters. The third remaining three way catalytic converter is located under the vehicle, upstream of the muffler, and has no 02 sensors monitoring its performance.

Disconnect Sensor Press the connector and pull it away to unplug the oxygen sensor. Place the oxygen sensor socket on the sensor and break it loose. Removing the oxygen sensor on an old ACURA may be difficult at first due to rust. If the sensor doesn’t come off, spray penetrating oil near the threads and wait at least 15 minutes.

What are the symptoms of a P0158 DTC?

Symptoms of a P0158 DTC may include: MIL (Malfunction Indicator Lamp) on Engine loses power and misses intermittently May exhibit loss of fuel efficiency Potential causes of an P0158 code include: Wiring in contact with exhaust components Engine running rich (If other codes are present)
