P2031 OBD Error Code: Problem & Solutions

Do you want to know more about the P2031 fault code? Don’t worry! Parts Avatar Canada is here at your service. If the engine control module would detect a variation in the voltage coming from the exhaust gas temperature sensor that is outside the parameters set by the automobile manufacturer, then it would store the P2031 error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the Exhaust Gas Temperature EGT Sensor Circuit Bank 1 Sensor 2?

• The connectors or terminals might be sometimes loose or corroded
• Faulty wires or missing insulation might cause a short directly to ground
• Unusable sensor
• There might be a cat back exhaust system without EGT provisions installed
• Failure in the computer

1. Exhaust Gas Recirculation Valve - It is auto part commonly found on many road going automobiles. It is a part of the vehicle’s exhaust gas recirculation (EGR) system, an emissions system that is designed to recirculate exhaust gases back into the vehicle’s intake so that it can reduce cylinder temperatures and NOx emissions. Purchase top notch exhaust gas recirculation valve from us at economical prices.
2. Engine Control Module - If there is any corrosion or breaks in the internal wiring of the harness, then it can cause a short in the ECM or can also cause corrosion in the ECM through the wiring harness. You can always rely on us as we have best auto parts for our customers.
3. Oxygen Sensor - Inspect for faulty O2 sensor that can affect the engine combustion process and the exhaust emissions. Thus, it is important to understand its importance and replace faulty oxygen sensor now!
4. Powertrain Control Module - The onboard computer, or powertrain control module is the brain of the engine control system. Now if the brain is not working properly, then neither is the car engine. Get it replaced before the situation gets worse.
5. Electronic Control Unit - Is your car jump starting on reverse polarity? Or are you facing some intermittent starting issues? If yes, then it indicates that your electronic control unit is bad. So it is very important to replace the defective electronic control unit with us at equitable prices.
6. Diagnostic Tools - Buy quality diagnostic tools to check and diagnose OBD code P2031 error with the help of experienced mechanic. Visit us today!

There could be countless symptoms which that would accompany with this fault code. Willing to know some common symptoms of OBD Trouble Code P2031? Your wish is our demand. Have a look at them below:

Common Symptoms

• Check engine light might come into signal
• A code for a failure in the EGT sensor circuit would be set in the engine control module
• Car engine might start running too rich or lean
• Leakage of exhaust before the sensor 

Looking out for some ways with the help of which you can correct this fault code? Then you have arrived at the correct place. We are here to help you out, so you must check out the steps mentioned below as follows:

• You must remove and clean the excessive soot and ash off of the EGT sensor
• Carefully adjust the faults in the EGT sensor
• Recondition the non-functioning wiring
• It is necessary to perform proper service of the exhaust leak in the pipe connection above the sensor
• Adjust the flawed electronic control unit

We are sure that now all your issues would be resolved.

It is essential to diagnose this fault code. Here are some steps which a mechanic should follow for diagnosing the problem that triggered a P2031 code to be stored:

• The mechanic or the technician will use a diagnostic scanner or code reader like DVOM to visually scan for the error codes in the vehicle.
• After performing a careful inspection, every of the stored codes and freeze frame data are retrieved as it can help down the way for further diagnosis process.
• He should scan as well as document the codes in the engine control module and then the freeze frame data should be looked upon for some failures.
• Most often he has to inspect the EGT sensor and wiring itself to see if they are faulty or damaged.
• Examine the exhaust temperature of the EGT sensor 1 for bank 1 and then it should be compared to the EGT sensor 2 for bank 1.
• After that the sensor should be replaced if its reading are not as per the specifications set by the manufacturer.
• Every time a repair work is carried out, make sure that the mechanic test drives the vehicle after every repair so that the diagnosis is successful. This can eventually help him to know as to where the error occurred.

Common Mistakes When Diagnosing The P2031 Code

• Many a times the mechanic might not remove the EGT sensor and forget to inspect for excessive soot or ash on the sensor.
• Make sure that the EGT sensor is cleaned properly and it should be retested first before replacing it directly.
