EGR temperature refers to the temperature of exhaust gases recirculated back into the engine's intake system through the Exhaust Gas Recirculation (EGR) system. This process helps reduce nitrogen oxide (NOx) emissions by lowering the combustion temperature. Monitoring EGR temperature is crucial for optimizing engine performance and ensuring compliance with emissions regulations. High EGR temperatures can indicate issues such as clogging or malfunctioning components within the system.

Where is the egr sensor located in your Nissan 200sx?
EGR sensor ( gas temperature sensor ) is monted near the EGR valve, which is install into the EGR tube.
Where is the EGR temperature sensor located on a 240sx?
The EGR temperature sensor is located in the intake manifold between cylinders 3 and 4
Where is the EGR temperature sensor located on a 1997 Mercury Villager?
On the EGR valve assembly.
What is the function of an EGR Valve on a 88 Nissan sentra?
The EGR valve and the EGR sensor work together. The EGR gas temperature sensor is mounted near the EGR valve. The sensor detects the temperature of the exhaust as it moves through the valve. The information is sent to the ECM and in turn the EGR on/off time is regulated precisely and more efficiently. Any malfunction with the EGR gas temperature sensor will set off a code 35 ( Info taken from HAYNES MANUAL)
Where is egr temperature sensor on Volvo d16?
The EGR temperature sensor on a Volvo D16 engine is typically located on the exhaust gas recirculation (EGR) system, specifically near the EGR cooler or manifold. It measures the temperature of the exhaust gases before they enter the EGR system. To locate it precisely, refer to the engine's service manual, as the exact position can vary by model and year. Make sure to follow safety protocols when inspecting or replacing the sensor.
Where is the EGR valve on 2002 Mazda millenia?
The EGR valve is connected above the water hose on the 2002 Mazda Millennia. The EGR valve is responsible for lowering the temperature of the fuel.
How do you replace the egr temperature sensor for Nissan sentra?
Remove the wiring harness from the EGR temperature sensor. Remove the two retaining screws from the sensor. Reverse the process to install the new sensor.
Where is the EGR temperature sensor on a 2008 Ford F-550 6.4?
On a 2008 Ford F-550 with a 6.4L engine, the EGR (Exhaust Gas Recirculation) temperature sensor is typically located on the EGR cooler assembly. It is positioned near the EGR valve, often on the side or top of the cooler, where it can accurately measure the temperature of the exhaust gases entering the intake. Accessing it may require removing some engine components for better visibility and reach.
What does the acronym EGR represent and what does the EGR do?
Exhaust gas recirculation. The egr meters a small amount of exhaust gas back into the engine. This gas lowers the combustion temperature which lower the a mount of oxides of nitrogen in the exhaust.
What is p1409 obd2 code?
The P1409 OBD-II code indicates an issue with the Exhaust Gas Recirculation (EGR) system, specifically related to the EGR temperature sensor circuit. This code suggests that the engine control module (ECM) has detected an abnormal reading from the EGR temperature sensor, which can lead to increased emissions and engine performance issues. Common causes include a faulty EGR valve, a malfunctioning temperature sensor, or issues with wiring and connectors in the EGR system. It is advisable to diagnose and address the problem to maintain optimal engine performance and compliance with emissions standards.
If a 1995 Toyota Corolla check engine light has come on and the OBD is giving an error code 71 - EGR system how do you diagnose and repair this problem?
My Toyota manual for a 1991 Corolla DX says that error code #71 is used only for California specifications. Here is the official diagnosis, according to the manual: the EGR gas temperature sensor signal (THG) is below the total temperature of the intake air temperature plus 55 deg Cent. (99 degrees F) after driving for 25 seconds in EGR operation range. The manual then lists five trouble areas: 1- Open in EGR temperature sensor circuit; 2- Open in VSV circuit for EGR, 3- EGR vacuum hose disconnected, valve stuck; 4- Clogged in EGR gas passage; 5 - ECU.
What is a 71 egr system problem for a 1994 geo prizm 1.6?
My service manual says this occurs if the engine coolant temperature (ECT) is above 60C with the EGR temperature less than 70C for 50 seconds. There is a long flowchart too complicated to list but it basically says it's one of the following: 1. Open or short from the EGR temperature sensor to the ECM. 2. A bad EGR temperature sensor. 3. An open connection (BLK/RED) between the fuse/relay box and the EGR SV (solenoid vacuum valve which is next to the EGR valve. The fuse and relay box is located on the driver side in the engine compartment. It contains relays and large amperage fuses. 4. A bad EGR SV valve 5. A bad ECM I have never had to look into this error so I cannot comment further. Hope this helps.
