Diesel engines may experience varying degrees of power loss. Thanks to ever-stringent emissions legislation, exhaust gas temperature sensors are becoming increasingly popular in modern vehicles. In diesel engines, exhaust gas temperature sensors are also used to monitor the temperature of the diesel particulate filter (DPF) to establish the correct temperature for regeneration, reducing harmful emissions.

Ensure the exhaust system is cool before starting work. The code disappeared after I reconnected the sensor plug. This can result in an emissions test fail. The most common causes of code P246E are largely similar across all applications, and could include one or more of the following-. Excessively high exhaust gas temperatures can cause the failure of catalytic converters, DPF devices, mufflers, and other sensors in the exhaust system. Sorry I was about vague to start off with. Next disconnect the electrical connector and unscrew the sensor using a socket wrench, taking care not to damage nearby components. Any help would be appreciated. Testing the voltage on the engine end of the pigtail to ensure that there are five volts at this connector. Three or more EGT sensors may be used, with sensor(s) before the DPF and after the DPF. Turn the ignition on and confirm that the check engine light is extinguished and that the exhaust system is functioning correctly. Conversely, their resistance goes down when the gas gets cooler. Need more help with a P247B code? The other design has a negative temperature coefficient, meaning that its electrical resistance decreases as its temperature rises.

Faulty exhaust gas temperature sensors can lead to unnecessary regenerations causing inconvenience for the driver. Both the EGR temp sensors and the exhaust gas temp sensors are measuring exhaust temperature, but the platforms using EGR temp sensors measure the temperature of the gas entering the EGR cooler. Making sense of your sensors: Exhaust gas temperature sensor. Also doesa someone have a part number for the 2010 A4 B8 2. In some circumstances this can save a lot of time in the long run by pointing you in the right direction. Continuity tests should always be performed with the power removed from the circuit and the normal readings for wiring and connections should be 0 ohms of resistance. Based on the specific type of sensor, resistance should increase or decrease as the temperature rises and heat gun can be utilized to perform a bench check of this component. Diagnosing this kind of trouble code might require you to use a scan tool and inspect the affected system for signs of damage. If this process identifies the absence of a power source or ground, continuity testing may be required to check the integrity of the wiring, connectors and other components. Therefore, we strongly recommend that you consult reliable service/repair information for the affected vehicle to locate and identify the exhaust gas temperature sensor(s) correctly.

Regeneration is the clearing of soot from the DPF, which is done by superheating the particulate filter. Common mistakes may include: Replacing the ECU or the exhaust gas temperature sensor when damaged wiring or another component is the issue. Extreme heat is often a cause of failure over time. And because they're a high failure part, they're becoming an increasingly popular repair too. Why do exhaust gas temperature sensors fail?

The resistance level of the exhaust gas temperature sensor should vary proportional to temperature increases and decreases. To diagnose a faulty exhaust gas temperature sensor, consider the following steps: - Conduct an electronic test and read any fault codes using a diagnostic tool. What are some common repairs for this code? Get Help with P246E. NTC-type sensors are more likely to trigger the engine check light on failure. If the voltage sent to the PCM exceeds the predetermined limits set by the vehicle manufacturer, the vehicle will store this code. Where is the P246E sensor located? If the exhaust gas temperature is faulty, then it needs to be replaced – simply follow the best-practice advice: - Locate the faulty sensor. Handle carefully to prevent damage to the component. The temperature inside the DPF increases whenever it fills up with soot. In most cases, it's best to take your vehicle to a professional mechanic. NOTE: It is important to note that failures of exhaust gas temperature sensors with positive temperature coefficients are often misdiagnosed as DPF failures.

Exhaust gas temperature sensors are incorporated in diesel engines, gasoline burning engines, and even turbocharged engines. Install the new exhaust gas temperature sensor and torque tighten to vehicle manufacturer's recommendations. A faulty exhaust gas temperature sensor can negatively affect a vehicle's after-treatment system, resulting in the following symptoms: - Check engine light: if the ECU detects a problem with the sensor or signal, it will trigger the check engine light to come on. Some diesel vehicles have a diesel particulate filter that burns particles in the exhaust gas, turning them into harmless substances. Repairing a P2471 code can become a challenging task without the necessary tools and skillset to test the exhaust gas temperature sensor. Repairs that may fix the P0546 code may include: Keep in mind that one of the possible causes of this code – installing a catback system in place of the catalytic converter – is against the law in many states due to these systems creating high emissions levels. Make sure you're working on the right sensor before checking or changing parts. Note, though, that apart from temperature sensors, the exhaust systems of many late-model vehicles can contain as many as a dozen or more other sensors, which means that testing or replacing the wrong sensor(s) is an easy mistake to make. If not attended to promptly, this code indicates a problem that could lead to catalytic converter damage. In the case of diesel particulate filters, the temperature of the exhaust gas is a fairly good indicator of the soot load in the filter, so when the temperature of the exhaust gas reaches a predefined threshold, the PCM will initiate a process that regenerates the diesel particulate filter to restore its ability to capture soot particles. I'm assuming it's the one on the cat as there is one before it which sits in the turbo. Checking the EGT sensor's resistance using an ohmmeter to ensure it has around 150 ohms.
Does anybody knows where the sensor is located? Inspect the sensor for any build-up of contaminants and clean with a clean, dry cloth as required. 0 off as a credit towards the repair. Installation advice.
It's a quick, fun read full of interesting anecdotes and examples that make the book's message more *concrete* (a-hem). Just as the majority of effective advertisements draw on a handful of sticky templates, inspirational stories have templates as well. Accounting principles, such as balance sheets and accounts receivable, became concrete when Georgia State University professors turned an introductory course into a semester-long simulation. The organization called a press conference at which they displayed a serving of movie popcorn juxtaposed with three meals: a bacon-and-eggs breakfast, a Big Mac-and-fries lunch, and a complete steak dinner.
