We participate in the Amazon, Advance Auto Parts, and eBayaffiliate programs. There is no fixed time limit for when they fail, but they typically last over 100,000 miles in Elantra. Thanks. This procedure assesses the condition of both oxygen sensors and catalytic converters by monitoring their reactions. Depending on the running condition, the voltage will range from 0.1 to 1 volt. To help you identify bank 1 sensor 2 on practically any vehicle, we share pictures of various makes and models and answer some of the most common questions. Bank 1 Sensor 2 is the second sensor on theexhaust pipe, located downstream behind the catalytic converter. False or implausible readings coming from any of the sensors may cause rough running or hesitation when speeding up. All you need is a wrench for this replacement job. As the exhaust gasses pass by it, the difference in oxygen levels between it and outside air creates a certain voltage. Being behind the catalytic converter, sensor 2 should give steadier readings. Even if your vehicle is not showing any signs of trouble, it is recommended to replace the upstream O2 sensor after 100,000 miles for optimal engine performance and fuel efficiency. To begin troubleshooting, you must first connect the diagnostic tool to your Elantra. With both engine and catalytic converter warmed up to running temperatures, downstream sensors should show values around 0,45 volts. Look under the hood of most cars today, and you will find that most engines come in two different configurations. Although most manufacturers use similar logic when naming the banks in their engines, there is no universal rule. The upstream O2 sensor helps in maintaining proper air to fuel ratio in the combustion chambers for maximum fuel efficiency and engine performance. The main purpose of downstream O2 sensor is to ensure that the catalytic converter is functioning properly. Screw in the new O2 sensor by hand and tighten it up with a wrench. Despite their different positions and tasks, all oxygen sensors operate on a similar and simple principle. ( ) , . The first one is between the engine and catalytic converter, and we call it upstream or sensor 1. If the oxygen in the exhaust gas increases, the air-fuel ratio becomes Lean. The most common sign of a bad Bank 1 Sensor 2 is the check engine light coming on. It measures raw exhaust fumes' composition, and the ECU uses this data to adjust the air-fuel mixture. Most auto repairs shops charge between $75 and $150 per hour. If you suspect a problem with O2 sensor in your Elantra, you should act immediately and get it checked by a professional mechanic. In-line engines have all cylinders in a row, with one cylinder head and intake and exhaust components. The downstream O2 sensor in Elantra 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. V6 andV8 engines havetwo banks and two catalytic converters, one for each bank. , : , . The HO2S generates a voltage between 0.1 and 0.9 V in response to oxygen in the exhaust gas. How popular is this code, among other codes? 2002 Hyundai Elantra Sensor Location, Need more information on how to fix the P0139 HYUNDAI code? The Heated Oxygen Sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. The engine runs too lean or too rich. Regardless of the bank, all oxygen sensors use the same naming pattern.

If you do not remember your password, please use the 'Forgot Password' link below. In such cases, the bank that contains cylinder number one is called "Bank 1.". The other one holds the 2nd cylinder, and we refer to it as bank 2. If you see any error code from P0130 to P0135 or from P0150 to P0155, it indicates a problem with the upstream oxygen sensor. Here, one side of the engine is a Bank 1, while the other is bank 2. Driving your Hyundai Elantra with a bad O2 sensor can cause sluggish and rough acceleration, along with high fuel consumption and emissions. Portions of the information contained in this table have been provided by wholecellerusa. Faulty oxygen sensors are the leading cause of premature catalytic converter failures. Note: The accuracy and accessibility of the resulting translation is not guaranteed. The core of each sensor is a probe that has a special sensing element inside it. In addition to the vehicle make, model, and engine type, you usually also have to type in the Vehicle Identification Number (VIN). All in-line engines have only one bank, although there are some exceptions when it comes to exhaust. The O2 sensor in Hyundai Elantra monitors the level of oxygen in the engines exhaust gases and reports the data to the control unit that continuously adjusts the air to fuel ratio in the engine to achieve maximum efficiency. The cylinder labeled as number 1 will always be on bank 1, while bank 2 will hold cylinder number 2. . Before getting to potential failure points, we must first make a brief explanation about how an oxygen sensor works. With the tool connected, turn on the ignition.
