2011-02-11· The new 2011 GM Diesel engines use an exhaust temp sensor that looked virtually identical to the Cat one. I spoke to a few diesel techs and received the diagnostic info and temp: resistance chart. It was tricky to to get this info as I asked several places without much luck. Not to name names, but thanks to the tech that got me what I needed. The only thing that you have to go is either …
2021-06-10· To locate the EGR temperature sensor, open the hood of your car. The EGR temperature sensor can be found in the exhaust manifold or near the EGR valve. Step 2: Disconnect the Battery To protect yourself from getting any electric shock, it is important that you disconnect the car battery.
(centre) and temperature sensor (bottom). PARTICULATE MATTER SENSOR Based on well-proven multi-layer technology Bosch has developed a ceramic exhaust-gas sensor for particulate matter (EGS-PM) which is shown in figures 2-4. On the sensing surface a DC voltage is applied to two inter-digital electrodes (IDE), on which soot particles are deposited from the exhaust gas during operation. The ...

2020-04-06· Connect a handheld vacuum pump to the sensor’s intake port. Push the end of the pump’s hose onto the exposed sensor port. Make sure the hose forms a tight seal on the port, or else you won’t be able to test the sensor accurately. Position the pump so you can easily see the pressure gauge and access the hand pump.
HTS exhaust gas temperature sensor with closed housing concept Closed housing sensors need to be designed to avoid the creation of a reducing atmosphere within the closed sensor tip. The closed protection pipe, mostly made of stainless steel, starts to oxidize at high temperatures from approx. 750°C. As a result, oxygen deposits are formed on the inside of the metal housing. Through the ...
The Powertrain Control Module continuously monitors the Exhaust Gas Temperature Sensor (EGTS) for proper circuit continuity and out of range high values. The EGTS is located in front of the Diesel Oxidation Catalyst (DOC) and/or in front of the Diesel Particulate Filter (DPF). The EGTS detects exhaust gas temperature and converts it into a voltage and feeds back to the
This diagnostic trouble code (DTC) P0546 refers to the condition of the EGT (exhaust gas temperature) sensor located in the "up" pipe forward of the catalytic converter. Its sole purpose in life is to protect the converter from damage due to excessive heat. Code P0545 is a similar code which states that the circuit shows "low" voltage. Both relate to the condition of the sensor and the ...
The exhaust gas temperature sensors (EGTS), which are located in front of the Diesel Oxidation Catalyst (DOC) and/or in front of the Diesel Particulate Filter (DPF), are used to detect exhaust gas temperature. It converts the exhaust temperature into a voltage and the input signal sent to the engine ECM. This voltage signal is used by the ECM for DPF regeneration, to improve/control emissions, fuel …
TEMPERATURE DIFFERENTIAL TEST The conversion process produces heat. So, exhaust gases entering the converter should be cooler than the gases exiting the converter. The temperature differential test measures the surface temperature at the inlet and outlet bushings of the converter.
3Please check the Exhaust Gas Temperature (EGT) signal in ServiceMaxx. Start engine, run at high idle and note if the temperature goes up. The temperature should eventually start increasing. Does the temperature increase? Yes: Go to step 7 No: Go to step 4 StepAction Decision 4Is the temperature stuck at 284 F? Yes: Go to step 5 No: Go to step 7 StepAction Decision 5Please check EGT sensor ...
Exhaust Gas Temperature EGT Sensor Circuit Bank 1 Sensor 2. What does that mean? This is a generic powertrain code, which means it covers all makes/models, 1996-newer. However, specific troubleshooting steps will vary depending on the vehicle. This diagnostic trouble code (DTC) P2031 refers to the condition of the EGT (exhaust gas temperature) sensor located in the "up" pipe forward of the ...
2016-01-07· The sensor is installed in between the exhaust and intake manifold, and monitors the temperature of the exhaust gases. When the temperature rises, the EGR temperature sensor will send a signal to the computer that will increase the flow in order to reduce pressure and temperature of the system. When the sensor fails or has any issues it can cause problems with the EGR system, …
2020-04-06· An exhaust pressure sensor, also known as an EBP or DPF sensor, measures differences between your vehicle’s exhaust before and after it passes through a filter. This helps determine if you need to clean or replace the filter to avoid clogs. If the sensor doesn’t work properly, it could make your check engine light come on and cause the engine to hesitate or stumble. If you want to check ...
2020-06-01· Your vehicle’s temperature sensor is an important component of your engine’s cooling system, so if you’re having problems with your car or truck overheating, you may have a faulty sensor. Luckily, replacing a temperature sensor is as simple as plugging in a new one. However, you should test your sensor first to make sure that’s where the problem lies, and you don’t have a deeper ...
Figure 1 – EGT Sensors 1 & 2 Check the sensor’s static resistance at ambient temperature (0-50°C/32-122°F) with a Digital Volt/Ohmmeter (DVOM) (see Figure 2). The resistance must be within the 100KΩ~500KΩ range. If the resistance is above or below this range, replace the EGT temperature sensor. Figure 2 – EGT Sensor Connector

The only purpose in life is to protect the inverter from damage due to excessive heat. This code means that the circuit is intermittently malfunctioning.
2015-03-14· Apparently, the first exhaust temperature sensor is out of range, and this is what triggers the check engine signal. Their diagnostic: 1st sensor 150C (approx 300 F), the other three exhaust sensors in the low 200F range - the temperature difference is what triggers the CEL. Their recommendation: replace the 1st sensor. Estimate: 6 hours labor ( not easy to work in that area) - …
