Guide To P242D OBD Error Code Solutions

<<See All OBD Codes

The trouble code P242D can be explicated as Exhaust Gas Temperature Sensor Circuit High Bank 1 Sensor 3. 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 P242D 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 High Bank 1 Sensor 3?

• Dripping in the exhaust
• Unacceptable electrical connection in the sensor 3 bank 1 EGT circuit
• Issue of unbolted sensor 3 bank 1 EGT harness
• Imperfect bank 1 sensor 3 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 P242D 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!
6. Fuel Injection – This system is responsible for supplying fuel with certain pressure, thus assisting the fuel delivery system and engine combustion process. Replace faulty/damaged injectors now!
7. Engine Wiring Harness – Damaged, broken or corroded wiring can cause the fuel delivery system to fail and the components to not work properly. These are easier to check and replace. Purchase new wiring harness and replace the faulty one.

Well, if you are looking to know about the common symptoms related to this error code P242D, we are have worked out a small list to help you discover this error code with your vehicle.

Common Symptoms

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

Fixing problems with your car is not as easy as it might seem. You need to be extremely careful and follow certain steps.

• 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 1 sensor 3
• Carefully mend the leakage in the exhaust
• Adjust the flawed wiring

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

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 1 sensor 3 exhaust gas temperature readings and then it should be compared to the bank 2. Then, use a multimeter to inspect the EGT bank 1 sensor 3 resistance. If nothing else is seen, then it is essential to use a temperature gauge to assess the EGT sensor readings accuracy.

Common Mistakes When Diagnosing The P242D 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.
