As its name suggests, the exhaust gas temperature sensor measures the temperature of the exhaust gas. Either way, the PCM will continually convert an exhaust temperature sensors' electrical resistance to an exhaust gas temperature while the engine is running, and the PCM will take appropriate action to reduce the exhaust gas' temperature based on this calculated value. In petrol engines, its main role is to protect key components from the higher temperatures common with downsized engines – so if the sensor detects excessive temperatures, the ECU will reduce the temperature, by lowering boost pressure in the case of the turbocharger, for example, or increasing the quantity of fuel injected for the catalytic converter. 99 donation via the payment button below. They keep track of the temperature of the exhaust gases produced by the engine. Does anybody knows where the sensor is located? 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.

Exhaust Gas Temperature Sensor Bank 1 Sensor 4 Locations
The one I think it is, is the one which has the crows foot socket over it. How do I replace an exhaust gas temperature sensor? If the exhaust gas temperature is faulty, then it needs to be replaced – simply follow the best-practice advice: - Locate the faulty sensor. The P0546 code means Exhaust Gas Temperature Sensor (EGT) Circuit High Bank 1 Sensor 1. Although exhaust gas temperature sensors are not yet in widespread use, on some applications, the exhaust gas temperature is measured at only one point in the exhaust system, while in many other applications, the exhaust gas temperature is measured at multiple points, and for various reasons. Although generic, the exact repair steps may vary depending on year, make, model and powertrain configuration. Would just like a bit of clarification as it's a nightmare to take off. That sensor is located in the exhaust just behind the EGR cooler in a very awkward location. Prepare the new sensor, applying anti-seize compound to the thread where necessary. What are common exhaust gas temperature sensor fault codes? Inspecting connectors for corrosion or loose connections. The most common causes of code P246E are largely similar across all applications, and could include one or more of the following-.
Exhaust Gas Temperature Sensor Bank 1 Sensor 4 Location Code
The ECU recognizes these voltage variations and reacts accordingly, adjusting ignition timing or the air/fuel mixture to lower the exhaust gas temperature and protect the catalytic converter. Exhaust Gas Temperature Out of Range Bank 1 Sensor 4. Inspecting wires for missing insulation or other damage that could cause a short to ground. Faulty or damaged wiring. If the voltage stays the same or changes rapidly, this as an indication that the exhaust gas temperature sensor requires replacement. Thanks in advance for any response. The advanced steps become very vehicle specific and require the appropriate advanced equipment to perform accurately. The exhaust gas temperature (EGT) sensor plays an important role in controlling the emission levels of a diesel vehicle. Engine may overheat. If not attended to promptly, this code indicates a problem that could lead to catalytic converter damage. There are several problems that can cause the sensor to send an excessive voltage signal to the PCM, including: The symptoms of this code typically only include the stored code itself, as well as a lit Check Engine Light. NOTE: It is important to note that failures of exhaust gas temperature sensors with positive temperature coefficients are often misdiagnosed as DPF failures. Common mistakes may include: Replacing the ECU or the exhaust gas temperature sensor when damaged wiring or another component is the issue. In some cases, multiple additional EGR, DPF, and or SCR (Selective Catalytic Reduction) related codes may be present along with code P246E.

With vehicle ignition turned on, and the plug on the EGT sensor disconnected, measure the voltage at the sensor's connector – there should be 5 volts. Hopefully, the information in this article has been helpful to point you in the right direction to correct the problem with your exhaust gas temperature out of range bank 1 sensor 4 circuit fault code. In a TechAssist bulletin, Lucas explain that these sensors protect vital exhaust components from overheating and help to control emissions. The second step is to locate all of the components within this circuit and perform a thorough visual inspection to check the associated wiring for obvious defects such as scraping, rubbing, bare wires, or burn spots.
Exhaust Gas Temperature Sensor Bank 1 Sensor 4 Location Vacances
Defective or malfunctioning exhaust gas temperature sensor. Lucas say a common problem with all wired sensors is that wires can break, especially if subjected to harsh twists and turns. The vehicle may fail an emissions test. To help you out, here's a short clip showing what the process might involve. Please comment below describing your issue as well as the specifics of your vehicle (make, model, year, miles, and engine), and one of our mechanics will respond as soon as possible.
If the sensor is threaded, clean the thread in the exhaust pipe with a cleaning tap. There are usually two EGT sensors in light-duty diesel vehicles that monitor the exhaust gas once it enters and exits the DPF. Apply copper grease on the sensor thread only. As you inspect the sensor's connectors for corrosion or loose connections, make sure you go up the pigtail to the connector to make sure that one is secure as well. A faulty sensor communicating incorrect voltages can result in poor fuel efficiency because the DPF regeneration takes longer to complete.
