P2034 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P2034 can be explicated as Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 2. This trouble code is generic, which would mean that it can apply to all the vehicles which are equipped with the OBD-II or the vehicles which are made since 1996 up to the present. The specifications on the definition, the troubleshooting steps as well as repairs can always vary from one vehicle make to another. This can happen because of a lot of reasons and the mechanic should diagnose the specific cause for this code. This error code refers to a malfunction in the exhaust gas temperature circuit. This code might be seen with some other EGR codes as well.

The brighter you are, the more you have to learn! That’s why we are here to provide you more knowledge about the P2034 trouble code. It is the engine control module which would examine the exhaust gas temperature sensor circuit. This trouble code would be set by the ECM when the exhaust gas temperature sensor circuit voltage would not be as per the parameters set by the manufacturer.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 2?

• Dripping in the exhaust
• Unacceptable electrical connection in the sensor 2 bank 2 EGT circuit
• Issue of unbolted sensor 2 bank 2 EGT harness
• Imperfect bank 2 sensor 2 EGT sensor

1. Engine Control Module - The solenoid might cause a short in the engine control module because of corrosion in the solenoid or the wire running from the solenoid to the ECM harness.
2. Electronic Control Unit – The ECU power management control module keeps in check the hybrid battery charging functions. If the ECU is faulty, the battery pack will not be able to properly get charged and thus, the ECU might need replacement.
3. Exhaust Gas Recirculation Valve - Did you just see check engine light flashing on your dashboard? If the computer would detect some fault with the automobile’s EGR valve circuit, then it would set up the check engine light so that the driver is notified about the fault. Don’t waste time and get them replaced or else P2034 code can turn up.
4. Powertrain Control Module - A trouble with the PCM would mean that it is unable to determine the right fuel mixture and would send the car engine either more or less fuel than it requires. Now when the engine gets more, the carbon emission would increase and fuel economy would drop. In case of the opposite, the engine will choke, stutter, and might start stalling sometimes.
5. Diagnostic Tool – Usually any OBD code problem requires deep insight into the problem and high grade tools in order to fix it properly. Thus, buy quality diagnostic tools form us!

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P2034 here:

Common Symptoms

• Illumination in the service engine soon light
• There might be no other symptoms

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 P2034:

• You must fix the inferior quality electrical connection
• It is essential to restore the flawed PCM
• Rehabilitate the defaults in the exhaust gas temperature sensor bank 2 sensor 2
• Carefully mend the leakage in the exhaust
• Adjust the flawed wiring

If you want to easily diagnose this trouble code, then you must follow the steps which are mentioned here as below:

The first and the foremost step is to use a scan tool to inspect for any codes in the automobile’s engine control module. Just keep in mind that there might be some current, pending, or history codes, so it is very important to note all of them. Carefully look at the freeze frame data for each code. After that the codes should be cleared up. Now once you have cleared all the stored codes, the vehicle should be taken out on a test drive to confirm if the check engine light comes back on or not. If you find out that the code is still appearing, then the mechanic must inspect what codes are stored this time. After that a visual inspection of defective or broken components should be performed. Use a scan tool to inspect the bank 2 sensor 2 exhaust gas temperature readings and then it should be compared to the bank 1. Then, use a multimeter to inspect the EGT bank 2 sensor 2 resistance. If nothing else is seen, the it is essential to use a temperature gauge to assess the EGT sensor readings accuracy.

Common Mistakes When Diagnosing The P2034 Code

• Common mistakes while diagnosing this trouble code are unnecessary and expensive replacements which usually happen when one don’t follow all the steps carefully.
• The most common mistake while diagnosing this code is missing out on diagnosing steps which further leads to the expensive and unnecessary replacements. It is always recommended to seek help of experienced diagnostician to avoid any mistakes.
