Exhaust Gas Temperature Sensor Bank 1 Sensor 4 Location

Like all wired sensors, severe vibration can also loosen internal connections and any bends or twists can cause the wire to break, making them particularly vulnerable to damage when replacing other components in the exhaust system. The ECU utilizes the input to control engine conditions and effectively reduce emissions. The two types of exhaust gas temperature sensors are negative temperature coefficient and positive temperature coefficient. One of the common causes of exhaust gas temperature sensor failure is exposure to excessively high temperatures – over 900°C in some case - the very thing they protect other components from. 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. OBD II fault code P246E is a generic code that is defined as, "Exhaust Gas Temperature Sensor Circuit Bank 1 Sensor 4", and is set when the PCM (Powertrain Control Module) detects a failure, malfunction, or defect in an electrical circuit that is associated with the exhaust gas temperature sensor that is labeled #4 on bank 1. That sensor is located in the exhaust just behind the EGR cooler in a very awkward location. To test the sensor, use a separate IR measurement device, and compare the readings to the live data obtained when using a diagnostic tool. Code||Fault Location||Probable Cause|.

Ziptie to replace the one (black, IIRC) I had to cut. 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. I couldn't loosen the sensor, but disconnected its plug when trying to replace it. The P0546 code means Exhaust Gas Temperature Sensor (EGT) Circuit High Bank 1 Sensor 1. Thanks to ever-stringent emissions legislation, exhaust gas temperature sensors are becoming increasingly popular in modern vehicles. Have the EGT Sensor 4 Bank 1 error coming up on my VAGCOM wiht the engine light in the dash. 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. Prepare the new sensor, applying anti-seize compound to the thread where necessary.

Refer to a vehicle specific resource to determine which is the appropriate bank and sensor location for your particular year / make / model / engine combination. 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. If you're not confident about conducting diagnostic tests on your vehicle, it's a good idea to bring it to a professional mechanic. A reset of the ECU may be required. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic for $114. OBD-II trouble code P247B is associated with the exhaust gas temperature out of range bank 1 sensor 4 circuit. Now reconnect the diagnostic tool and delete any related fault codes. P0546 indicates that there is a malfunction related to the exhaust gas temperature sensor circuit. Testing the voltage on the engine end of the pigtail to ensure that there are five volts at this connector. If the exhaust gas temperature is faulty, then it needs to be replaced – simply follow the best-practice advice: - Locate the faulty sensor.

And because they're a high failure part, they're becoming an increasingly popular repair too. Defective or malfunctioning exhaust gas temperature sensor. When the temperature of the exhaust gas increases, their electrical resistance increases. All our repairs are backed by our 12-month / 12, 000-mile warranty. Making sense of your sensors: Exhaust gas temperature sensor. If the controller doesn't get the right response from the number four sensor on bank one, it will set the generic code P2471.

Exhaust Gas Temperature Sensor Bank 1 Sensor 4 Location Subnautica

This exhaust gas is directed into the combustion chambers to reduce NOx emissions rather than being sent directly to the diesel particulate filter. Bank 1 refers to the bank of cylinders on V-type engines that contains cylinder #1. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20. Thus, when the exhaust gas temperature sensor registers a maximum allowable temperature threshold, it relays this information to the PCM, which will then reduce the boost pressure to lower the exhaust gas temperature. The designation of the sensors starts with B, it can be B12, B19 and so forth... To find out more about and to view Lucas Electrical's range of exhaust gas temperature sensors, select 'more details' below. 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.

Stored trouble code and an illuminated warning light. YourMechanic offers certified mobile mechanics who will come to your home or office to diagnose and repair your vehicle. In some cases, multiple unnecessary DPF regenerations may occur during a single trip, which will have serious negative effects on fuel consumption for some vehicles. I hope is.... P0544That's the description not a code.... Unnecessary DPF regeneration: faulty sensors can also lead to unnecessary regenerations, causing inconvenience to the vehicle owner. The severity of this code can vary tremendously from just an illuminated check engine light on a vehicle that starts and runs to an automobile that will stall or not start at all. Turn the engine on and check if the exhaust system works properly. Like the catalytic converter in gas vehicles, the DPF needs a certain temperature to work properly. The plug is easy to access, being attached to the firewall just behind the EGR cooler. The PCM regularly checks the EGT sensors. Nonetheless, if a failure, malfunction, or defect occurs that affects the operation of the sensor or the quality of its signals, the PCM will recognize that it cannot control the exhaust gas' temperature effectively, and it will set a trouble code and illuminate a warning light as a result. What are some of the common causes of the code?

Removing carbon buildup from sensor. P2470 - 000 - Short to Ground - MIL ON. As their name suggests, exhaust gas temperature sensors measure the temperature of the exhaust gas as it passes through the exhaust system. Repairing or replacing faulty wiring. Engine may overheat.

This can result in an emissions test fail. Need more help with a P247B code? 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. Checking the EGT sensor's resistance using an ohmmeter to ensure it has around 150 ohms. Handle carefully to prevent damage to the component. Has anyone got a link for the work involved to get to and replace this part? While code P2471 refers to the exhaust gas temperature sensors measuring exhaust flow into the diesel particulate filter, it's important to note that some diesel engines will have a different exhaust gas temperature sensor as a part of their EGR systems. What Does Code P246E Mean? Buy Part On Amazon). This process also improves performance and fuel economy.

Hello everybody, I'm the proud owner of a 2012 Jetta Sportwagen TDI with about 53, 300 miles on it and I've a couple of questions. We recommend Torque Pro. Regeneration is the clearing of soot from the DPF, which is done by superheating the particulate filter. Symptoms of a P247B trouble code may include: - Engine may stall. Otherwise, you can go ahead and do the job yourself. As soon as the EGT sensors send a signal to the PCM, the regeneration process begins. The exhaust gas temperature sensor should be removed to inspected for excessive carbon buildup. 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. PTC-type sensor failures are often misdiagnosed as DPF issues as after failure they continue to function sending incorrect signals to the ECU affecting the DPF regeneration process.

Thanks in advance for any response. It is located between the exhaust manifold and the catalytic converter. 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. The code disappeared after I reconnected the sensor plug. These procedures require a digital multi meter and the specific technical references for the vehicle. Check engine light illuminated. Any help would be appreciated. Lucas say that some sensors are harder to diagnose than others. The one I think it is, is the one which has the crows foot socket over it.
