P2298 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2298 can be defined as O2 Sensor out of Range during Deceleration Bank 2 Sensor 1. It is a generic code for a voltage issue with the oxygen sensor in that the signal being sent from the sensor to the engine computer is not as per the manufacturer’s parameters.

1. Engine Control Module - There can be some engine performance issues due to faulty engine control module. If the ECM fails or has any problems it can lead to performance issues with the vehicle like misfires, hesitation, loss of power, and sometimes even decreased fuel economy.
2. Fuel Delivery System Parts - If you want your car engine to run perfectly, then you will need an efficient fuel system for that. The parts of fuel system are fuel tank, filter, pump, tank and injector or carburetor. If there is a failure in any of these components, then it would lead to faults in the entire fuel system. We have top notch fuel delivery system parts for our dear customers.
3. Powertrain Control Module - PCM stands for powertrain control module. It is a car part, a control unit which is utilized on motor vehicles. It is generally a combined control unit, consisting of the engine control unit (ECU) and the transmission control unit (TCU).
4. Oxygen Sensor - If the fuel to air ratio is not correct, the engine may work in lean or rich conditions. This not only hampers the performance output, but also affects the fuel economy, exhaust emissions and acceleration. Thus, a faulty oxygen sensor must be replaced as if it important for keeping in checks the oxygen levels entering/exiting the engine.
5. Electronic Control Unit - If your automobile's check engine light remains on constantly, and never goes off, there's a good chance that your vehicle has a damaged electronic control unit. There are a lot of reasons why a car's check engine light will remain on. The most common reason is a defective ECU.
6. Diagnostic Tools - It is always advisable to use correct tools and equipment while resolving any OBD code issue as even small mistakes can lead to wrong diagnosis. Thus, always take help from a professional who has the knowledge and experience to such tools in efficient manner. Buy new quality diagnostic tools from us today!

Our main motive is to achieve customer satisfaction as for us our customers are everything and that’s why we will help you to diagnose P2298 code by mentioning some major symptoms below:

Common Symptoms

• The service engine soon light can start lighting up
• Inferior engine performance
• Decrease in the fuel mileage
• Black smoke might start coming out from the tailpipe

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P2298:

• Rehabilitate the defaults in the oxygen sensor and its wiring
• Carefully adjust the faults in the upstream bank 2 oxygen sensor
• Recondition the non-functioning exhaust and engine vacuum system parts
• It is necessary to perform proper service of the unsound PCM/ECM
• Adjust the flawed ECU

However, if you face any issue then we have stocked a wide range of best priced pcm, ecm, oxygen sensor, car engine parts, ecm module, ecu, pcm module and more to help you out in fixing your car.

Here are some steps which you should follow in order to diagnose this fault code:

• This is a general type of error code which is diagnosed with the help of a scanner.
• The mechanic will insert a scanner to diagnostic port of the vehicle and recover the codes and freeze frame data.
• If he happens to find any additional error codes, he has to address them as well.
• Once it is done, he has to reset the vehicle, and then test drive to see if the error code appears.
• If the error code does not return, then there can be an erratic condition.
• Then the mechanic has to check the wires, connectors and other electrical components and quickly replace them if he finds them to be damaged or defective.
• Check for the voltage from the oxygen sensor as well as the air/fuel mixture for error. It the mechanic finds the fault in the oxygen sensor, replace it immediately.
• There are some manufactures which utilize heated sensors so an engine can enter closed loop operation faster.
• The ground for these can go bad, so that’s why the technician utilizes a professional-grade multi-meter to decide resistance.
• After that the mechanic should clear up the codes and then the vehicle should be driven with the scanner connected so that it can examine the poor voltage reading from the oxygen sensor.
• Parts or components should not be replaced with reference to only a P2298 DTC. The vehicle service manual should be consulted for more information on possible causes of the fault, along with required testing.
• If all the components seems to work perfectly, inspect the PCM for faults and replacement along with reprogramming.

Common Mistakes When Diagnosing The P2298 Code

• A lot of mechanics simply replace the oxygen sensor thinking that it might cause this error code, but that might not be true in reality.
• If there is a lean/rich condition caused by a leakage in the exhaust or vacuum, or a faulty wiring, a new oxygen sensor won’t help the problem at hand.
