P2466 - OBD Trouble Code

<<See All OBD Codes

The trouble code P2466 can be explained as Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 3. This diagnostic fault code is a generic powertrain code, which means that it would apply to the OBD-II equipped vehicles. The specific repair steps can vary as it depends upon the vehicle make and model. The engine control module, powertrain control module or the transmission control module monitors this circuit depending upon the particular automobile.

Do you want to know more about the P2466 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 P2466 error code. This would also give rise to the illumination of the check engine light.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Bank 2 Sensor 3?

• 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 P2466 error with the help of experienced mechanic. Visit us today!
7. Fuel Injector - Faulty fuel injector, it will cause rough idles and difficulty in starting. Also, it will affect the fuel economy and engine performance. Fuel injector can also crack or break leading to leakages and should be replaced immediately.
8. Diesel Exhaust Fluid Pump - The diesel exhaust fluid pump needs to work properly if the transmission system has to perform. If it is not functioning, the transmission may slip and cause harsh shifts too. Thus replace faulty pump now and buy a new one from us!
9. Manifold Absolute Pressure Sensor - The MAP sensor would fail by getting clogged, contaminated, or sometimes damaged. There can be times when the engine heat would “overcook” the electronics of the MAP sensor and can cause cracks vacuum lines. So it is very important to take proper care of the MAP sensor and in case you need a new one, then Parts Avatar is here at your service.

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 P2466 here:

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

After you know the symptoms of your vehicle’s problem, it becomes easy to detect it and get started with solving it. So, next on our list is few common steps to correct this issue with your vehicle.

• 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

Apart from the fuel injector, you might need to undergo few more replacements. You might need PCM, Diesel particulate filter, turbocharger, catalytic converter, Exhaust Gas Temperature, Exhaust System, ECU, Connectors, Temperature Sensor, EGR Valve, Fuel Injector and many other parts. Where to get them from? Well, if you want quality parts, then we can prove to be your dream destination.

• 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 3 for bank 2 and then it should be compared to the EGT sensor 2 for bank 2.
• 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 P2466 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.
