Most modern oxygen sensors have a heating element inside them, which helps achieve running conditions faster. () . Replacing the Rear Heated Oxygen Sensor Bank 1 usually takes care of the problem. There is no fixed time limit for when they fail, but they typically last over 100,000 miles in Elantra. The same will happen if the sensor fails to react during the rich or lean testing period. Something went wrong. You can diagnose the problem by connecting an OBD2 scanner to your vehicle. The O2 sensor, which is installed after the catalytic converter, is called downstream or sensor 2. The situation is quite simple with most in-line variants, as the whole engine is one bank. However, most modern engines incorporate a specific testing interval during which they run rich or lean for a short time. 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. To avoid mistakes and unnecessary repairs, make sure you have the correct information for your car. [ , . 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. Copyright 1995-2022 eBay Inc. All Rights Reserved.

The first one is located between the engine and catalytic converter, and we call it sensor 1 or an upstream sensor. It measures raw exhaust fumes' composition, and the ECU uses this data to adjust the air-fuel mixture. Just like its upstream counterpart, it measures the composition of exhaust gases. Knowing the right designation is much more important when dealing with engines in a V-configuration. Leave a comment below or tell us if the information above helps you fix the code. In such cases, the bank that contains cylinder number one is called "Bank 1.". If you see any error code from P0130 to P0135 or from P0150 to P0155, it indicates a problem with the upstream oxygen sensor. Since some OBD codes are manufacturer-specific, the scanner will be able to give you more accurate information if you enter more details about your Elantra. 2002 Hyundai Elantra Sensor Location, Need more information on how to fix the P0139 HYUNDAI code? Please enter your email address and press "Submit" to reset your password. The Engine Control Module (ECM) adjusts the fuel injection time so that the air-fuel ratio is nearly stoichiometric. One that is between the engine and the catalytic converter is upstream or sensor 1. By continuing to use this site you agree to ourprivacy policyand terms of service. What are the symptoms on your vehicle for the p0139 hyundai code? In-line engines have all cylinders in a row, with one cylinder head and intake and exhaust components. It is important that you enter this 100% correctly, otherwise the result of the search may be inaccurate. It is important to keep in mind thatYOUCANICwebsite services, content, and products are for informational purposes only. Faulty oxygen sensors are the leading cause of premature catalytic converter failures. Cleaning them off with a special solution is a stop-gap measure, and replacing the sensor is the only reliable solution. If there is any fault in the oxygen sensor, it usually illuminates the engine check light in the instrument cluster of Hyundai Elantra. The HO2S generates a voltage between 0.1 and 0.9 V in response to oxygen in the exhaust gas. Depending on the running condition, the voltage will range from 0.1 to 1 volt. Search p0139 hyundai Questions and Answers , 5 Most Common Reasons for Check Engine Light, Rear Heated Oxygen Sensor Bank 1 harness is open or shorted, Rear Heated Oxygen Sensor Bank 1 circuit poor electrical connection, Engine Light ON (or Service Engine Soon Warning Light). Do not confuse bank 1 sensor 2 with bank 1 sensor 1, which you can see when you open the hood. Since a rich or lean condition robs a vehicle of power, a bad oxygen sensor can cause poor acceleration. California Emissions; Bank 1 Sensor 2, Bank 1 Sensor 1; Upstream; ELANTRA GT Base Model, Upstream; Exc. The P0139 code is set when the Engine Control Module (ECM) detects that the rear O2 sensor takes more time to respond between rich and lean than the specified time. One of the most common causes of oxygen sensor failure is dirt and soot build-up on the probe itself. Every bank has an exhaust with two oxygen sensors. You can also look for marking on the valve covers or ignition cables to determine the cylinder pattern. The most common signs of bad O2 sensor in Hyundai Elantra are slow acceleration, loss of power, irregular idling, engine hesitation or jerking when accelerating, high fuel consumption, higher tailpipe emissions, foul odor from exhaust, check engine light illuminates, and sometimes stalling. The main purpose of downstream O2 sensor is to ensure that the catalytic converter is functioning properly. Seller assumes all responsibility for this listing. , , , , , , , !

Please try again later. Is Bank 1 Sensor 2 before or after the catalytic converter? If there is no voltage coming from the downstream oxygen sensor, the ECU will assume there is an issue. , *** - , : , . While this makes them more compact, the added complexity can make maintenance more difficult and expensive. As the exhaust gasses pass by it, the difference in oxygen levels between it and outside air creates a certain voltage. ( ) , . Typical fault codes that come up are: All oxygen sensors operate on the same principle. . The other one holds the 2nd cylinder, and we refer to it as bank 2. Driving your Elantra with a bad oxygen sensor can damage the engine or the catalytic converter, so you must act urgently to avoid more expensive repairs. These have two cylinder heads, one on each side of the engine, with separate intakes and exhausts. Always seek the advice of an automotive professional if you have a question regarding the operation and safety of your vehicle. So if your Elantra 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. The Heated Oxygen Sensor 2 (HO2S), after three way catalyst (manifold), monitors the oxygen level in the exhaust gas on each bank. A professional mechanic can swiftly diagnose the problem for you. This translation tool is for your convenience only. In theory, there should be no noticeable impact on engine performance if this sensor fails. Most auto repairs shops charge between $75 and $150 per hour. Although most manufacturers use similar logic when naming the banks in their engines, there is no universal rule. Note: The accuracy and accessibility of the resulting translation is not guaranteed. Youwill need to access and replace thebank 1 sensor 2 oxygen sensor from under the vehicle in most cars. If the oxygen sensor goes bad in Elantra, it does not send correct measured values to the engine control unit. RockAuto name, logo and, If you do not have an account but would like to check the status of an order, request a change, or report a problem with an order or shipment, please go to our, Downstream; w/ California Emissions; Bank 1 Sensor 2, Downstream; Exc. You can also perform a continuity test on the connector of the sensor with a multimeter to check if the heater circuit is broken. V-shaped engines have two banks, and one with cylinder 1 is what we refer to as bank 1. The major difference is that data that helps ECU determine if the catalytic converter is working properly. With both engine and catalytic converter warmed up to running temperatures, downstream sensors should show values around 0,45 volts.
