P2484 OBD Error Code: Problem & Solutions

<<See All OBD Codes

The trouble code P2484 can be defined as Exhaust Gas Temperature Sensor Circuit Intermittent/Erratic Bank 1 Sensor 5. Now you might be thinking that what does “Bank 1 Sensor 5” means? Keep reading further. Bank 1 refers to the back of cylinders without the number one cylinder. The sensor 5 would be the fifth exhaust gas temperature sensor from the motor following the exhaust to the rear of the automobile. The exhaust gas temperature sensor is being monitored by the engine control module. This trouble code would be set by the ECM when the exhaust gas temperature sensor circuit would not be as per the specifications set by the manufacturer.

The exhaust gas recirculation (EGR) temperature sensor is an important component that monitors the EGR gas temperature and sends the desired information to the car’s onboard computer system. Any problem with the EGR temperature sensor can cause damage to the EGR system and as a result, your car may fail to pass the emission test along with drivability issues.

When the EGT sensor 5 for bank 1 is not performing as per expectations, OBD code P2484 gets stored in the system.

What causes this problem with the Exhaust Gas Temperature Sensor Circuit Intermittent/Erratic Bank 1 Sensor 5?

• EGT sensor might face rough operating conditions
• Malfunctioning EGT sensor
• Some issues related to the Catalytic converter
• There can be inoperative ECM
• An engine might not be working at the right operating temperature
• Catalytic converter might be very slow to heat up

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. 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.
4. Exhaust Gas Recirculation Valve - If the PCM detects any fault in the vehicle’s EGR valve circuit, it will set up the check engine light so that the driver is notified about the fault. Properly check for the EGR valve faults leading to this OBD code getting stored in the system. Get the faulty EGR valve replaced or else this fault code can turn up.
5. Diesel Exhaust Fluid Pump – Faulty DEF pump can lead to increased emission and affected vehicle performance. It can also hamper the fuel economy and the power output of the vehicle. Thus, replace faulty DEF pump now!
6. 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!
7. Fluid Pump Control Module - If the control module is faulty, the pump will not be able to work properly and will not be able to transfer fluid to the transmission and hydraulic system efficiently. Thus, replacements are in order.
8. Oxygen Sensor - The O2 sensor can also be at fault leading to lean or rich engine conditions and thus affecting the engine performance and improper fuel consumption. Buy new sensor and replace the faulty one now!
   
9. Exhaust Gas Temperature Sensor - Alarmed? Check engine light illuminated? Excessively heating engine? All this is happening due to your faulty exhaust gas temperature sensor. Don’t know where to get yours? Tune into Parts Avatar now!
10. Diesel Particulate Filter - Your dirty or defective diesel particulate filter can not only lead to the error code P2484 but also problems with the engine note change and an increased engine idle. Log into Parts Avatar if you want to get your diesel particulate filter changed or repaired.
11. Fuel System Parts - Weary and damaged fuel system parts can often be problematic. So to add some spark to your ride you definitely need the perfect quality fuel system parts offered at Parts Avatar. Isn’t that just the perfect deal?
12. Exhaust System Parts - The inferior quality exhaust system parts can always be hazardous for the system also it is one of the primal causes behind the occurring of the error code P2484. Apart from the error code, it also leads to problems like excessive smoke emission from the vehicle’ exhaust. Tune into Parts Avatar for supreme quality exhaust system parts at economical prices.

For us our customers are everything, and that’s why we will help you to diagnose P2484 code by mentioning some important symptoms below:

Common Symptoms

• Reduced/abnormal engine performance
• Affected fuel efficiency
• Lean or rich exhaust codes
• Increased emissions from the tailpipe

Have a look at some ways with which you can correct the P2484 code:

• It is essential to reprogram the ECM to adapt to unexpected situations
• Repair or replace the quirky EGT sensor
• The ECM should be instructed to perform diesel particulate filter regeneration
• Carefully adjust the faults in the wiring damage in the EGT sensor circuit
• Recondition the non-functioning ECM
• Adjust the flawed catalytic converter

If you want to easily diagnose this fault code, then all you have to do is to follow the steps which are mentioned below:

• A technician begins by hooking the vehicle to an OBD-II scanner to verify that the code is present, and check for other codes. The freeze frame data along with current data is recorded, and the codes are then cleared to see if they reoccur.
• The trouble shooting specifications of each and every manufacturer would differ and that’s why here is a list of some common procedures which should be followed:
• Carefully inspect if there is any stored code and make sure to first diagnose all other relevant codes.
• Then the freeze frame data should be inspected properly. After that the technician should check all the exhaust system parts.
• The sensor connector should be removed and then examine for issues related to voltage and resistance.
• You can always perform suitable voltage and resistance tests as per the specifications of the manufacturer.
• Observe the exhaust gas temperatures by performing a test drive of the vehicle.
• Carefully remove the EGT sensor from the exhaust and then check for signs of contamination.
• If all the components check out, inspect for the fault in the PCM as it can sometime store wrong OBD code and thus might need replacement or reprogramming.

Common Mistakes When Diagnosing The P2484 Code

• A big mistake which is made by a lot of people is that they do not diagnose the error code which is appearing first, and before that they would start diagnosing other relevant codes which can cause more problems.
• Sometimes, the mechanic might simply replace the sensor without even investigating why the code was set,
• Other issue can be confusion in the mind of the mechanic regarding the right location of the sensor.
• The technician might fail to examine the wiring harness and the entire exhaust system.
