The DTC stands for Exhaust Gas Temp Too High Bank 2, which specifies the problem is coming from inside the engine bank that doesn’t house cylinder 1.

The Powertrain Control Module (PCM) inspects the Exhaust Gas Temperature (EGT) sensor for a false signal worth. This follows with a soaking for eight hours, and the PCM does a recording on the EGT sensor temperature worth at key ON and engine OFF. After running the vehicle for several minutes at speeds that largely exceed more than 40.2 km/h (25 mph) the PCM estimates a predicted key ON and engine OFF worth. The PCM finds out what the predicted EGT worth at key ON and engine OFF had to have been, which is grounded on inputs by other sensors. The test malfunctions as the variation between the predicted estimated worth and the exact recorded worth is even larger than 40°C (72°F).

What causes this problem with the Exhaust Gas Temperature Too High Bank 2?

• Defective Exhaust Gas Temperature (EGT)
• Open or shorted Exhaust Gas Temperature (EGT) harness
• Bad electrical connection to Exhaust Gas Temperature (EGT)
• Ultimate fluctuations in Ambient Temperature Soon after key ON when engine operates

1. Powertrain Control Module - Irregular engine behavior might detect a poor or failing PCM. A faltered computer may cause a vehicle to abruptly stall or fail in starting. If the PCM is dealing with any errors, it may resist the timing and fuel settings of the engine that might badly affect on the vehicle as it processes. A defective PCM may result in a vehicle that deals with a reduction in fuel efficiency, power, and acceleration. A defective PCM might cause a vehicle that struggles to start or faces challenges at restarting. If the PCM fails entirely, the vehicle stays dealing with a loss of engine power control, so it might fail to start or be facing challenges when running as an outcome. The engine could still be cranking, but have no crucial inputs sourced from the computer, so it will eventually be unable to start at all.
2. Exhaust Gas Temperature Sensor - A main symptom that is generically associated to a bad or failing EGR temperature sensor is engine ping or knock noises. If the EGR temperature sensor fails it will cause an error with the EGR system stream. This can result in rising temperatures within the cylinder, which is apt to causing engine ping or knock sounds. Engine ping or knock will make a noise like a metallic clanging sound that drives from the engine bay, and indicates that there is a problem with the burning process. Any problem that results in the engine ping or knock noises should be communicated immediately, as engine knock can result in crucial engine damage if it stays unchecked. Another main symptom of a bad or failing EGR temperature sensor is a Check Engine Light that illuminates. If the computer detects a problem with the sensor circuit or signal, it will trigger the Check Engine Light so this can notify the driver that there is an error. A wide variety of other errors can also activate the Check Engine Light, so scanning the vehicle for trouble codes is highly recommended. A failed emissions test is another main symptom of a problem with the EGR temperature sensor. There can be instances where the sensor will fail or send forward a false reading and cause a malfunction in the EGR system, without triggering the Check Engine Light. This will cause the vehicle to fail an emissions test, which can result in a widespread problem for settings within tense emission regulations.
3. Catalytic Converter – A major symptom that is generically related to a poor or failing catalytic converter is a decrease in engine performance. The catalytic converter is equipped into the vehicle’s exhaust system, and as an outcome, can greatly affect the engine’s performance if it builds on any errors. A plugged converter will limit exhaust stream, while a split converter will leak toxic emission. Any defect can badly affect the engine performance and result in a decrease in power and acceleration, including fuel economy. Sounds of ratting coming from under the vehicle are another major symptom of a poor or failing catalytic converter. If a catalytic converter becomes aged or damaged inside from too many rich fuel compounds, the catalyst coated honeycomb meshes found inside of the converter can fall down or break up, which causes a rattling sound. The rattling sound might be more evident when starting the vehicle and will get worse over duration of time. A poor or failing catalytic converter can also cause a Check Engine Light to illuminate. The oxygen sensor and air-fuel ratio sensor in updated vehicles inspect the catalytic converter efficiency by tracing the emission levels within the exhaust. If the computer finds that the catalytic converter is not running properly, or not catalyzing the exhaust emissions correctly, it will trigger the Check Engine Light to make the driver aware of the problem. A range of other problems can trigger the Check Engine Light, so it is considered to scan the vehicle for error codes to be assured of the problem.

Our customers are very important to us, and this is the reason we will assist you to correctly diagnose P2429 code by describing a few essential symptoms as follows:

Common Symptoms

• Fuel pressure has dropped excessively
• Exhaust is rich or lean
• Fuel efficiency is decreased
• If not clearing the DPF this will return the ECU to the Limp Home Mode until correcting the occurrence.

There might not be any indications of this defect, outside of just the supplied code and an illuminated Check Engine or Service Engine Soon light. Reduced fuel efficiency is also feasibility.

Once you have comprehended all the symptoms and some generic causes underlying the OBD trouble code, we are available to assist you to better comprehend the methods and standards to correct the problem. As a way to properly solve the error, you have to follow these specific points, and resolve OBD trouble code P2429, so you will need to undertake replacing the following components:

• When exhaust temperatures reduce, with the engine off, circuit resistance hikes up and the feedback voltage signal to the PCM reduces.
• If there is an open in either the reference voltage or ground circuits, make use of the digital volt/ohmmeter to detect for progression, when disengaging all associated control modules by the circuit prior to detecting circuit resistance or controller damage that might happen, as well as resistance in all circuits.
• A few programs also make use of the inlet door to control air flow going in past the intake tube by fixing the extent of the case until the door opens in regards to the throttle position.
• If the code fails to come back instantly, you might have an irregular setting.

In achieving all this, you will have to get some high-end vehicle components such as PCM, EGT, and Ambient temperature, Engine overheating, Engine soon light, Catalytic converter, Freeze frame and even more. Wondering where will you find these items? Wondering what local store to visit? Why go to any local store when you can easily order our quality components on our website while sitting comfortably in your own home. Simply browse around our website and order your desired components today.

Scan the vehicle’s computer with an OBD-II reader to detect for coinciding error codes and record all freeze frame data.

• Clear the computer for all DTCs, and then test-drive the vehicle to affirm if they are returning.
• Visibly monitor the sensor, wiring, connectors, and other associated circuitry for any signs of damage or insecure connections.
• Monitor resistance of the exhaust gas temperature sensor by using a digital volt/ohmmeter.
• Heat up the sensor by using a heat gun as you connect to the ohmmeter as a way to check for the correct response, as the resistance should reduce with heat and hike up as the sensor cools down.
• Monitor the exhaust pipes for any sign of leaks
• Monitor the engine and associated parts that could be resulting for it to overheat.

Common Mistakes When Diagnosing the P2429 Code

A major common problem is replacing the oxygen sensor instead of the exhaust gas temperature sensor. This is evidently not going to solve the issue, and is a really good reason as to how crucial it is to obtain the proper specification for your car’s system so that you can specify where the right component is located.
