EXHAUST GAS TEMPERATURE (EGT) SENSORS 1 AND 2 – TEST …

temperature sensor. Figure 2 – EGT Sensor Connector 3. Check the sensor’s dynamic resistance by warming the sensor tip by hand or by using a standard 110V heat gun(see Figure 3 through 5s . )The temperature vs. resistance response is inversely proportional; therefore the resistance value shown on the DVOM should decrease a sensor is heateds the (see Figure 6). Stop applying heat if the ...

What is an EGR Sensor? - Garage Deed

2019-04-27· The EGR sensor main work is to get small amounts of exhaust fumes back to decrease the temperature and ultimately decrease combustion. The EGR is also giving pressure feedback that tells of any changes within the system. The sensor and the EGR valve works hand in hand to regulate the pressure such that when the pressure is low, the EGR valve will increase the flow and vice versa. The …

EGR Valve Temperature Sensor | EGR Gas Temp Sensor ...

Symptoms of a bad EGR temp sensor can be similar to those of a problem with an EGR valve itself. You might want to test the sensor before you replace it. One way to do this is to put the sensor in water and test the resistance of the sensor with a multimeter as you heat the water. As the temperature rises, the resistance of the sensor should decrease.

EGR temp sensor tested open. Bad? | IH8MUD Forum

2007-10-25· no mention in the FSM of using a hot water test for the EGR temp sensor. However, it does follow logically that it could be tested by that method, but there are no temp specs given for this EGR temp sensor. ie: the FSM does not say; " test at XX degrees for three minutes---" It tells you to check in the vehicle, sensor connector disconnected, with the engine warm after racing at 4000 rpm …

Exhaust Gas Temperature Sensor | TDIClub Forums

2014-10-07· I have 2009 Jetta TDI. My glowplug and check-engine light came on. I checked the code with my dongle and Torque app. The code is P0544, "exhaust gas temperature sensor circuit, bank 1". Further research online shows it's bank 1, sensor 1. The problem is my Bentley manual doesn't show a sensor #1. It shows sensor #4 and two sensors labeled #2.

EGR valve/Gas temp. sensor Question | Toyota Nation Forum

2011-04-28· the sensor could be bad. when the engine is hot disoncet the lines to it and check resistance on the sensor. 2k-4k at 302 degs f. 11k-15k at 212 degrs f. 69k-89k at 112 degs f. so if it reads back bad (mine was reading back 147k at normal temp) and if it's bad you can drop in a resistor to bypass that sensor making the car think that it's letting too much exaust (too hot). and the 6 pack …

EGR Temperature Sensor?????? | Toyota Nation Forum

2009-09-22· I checked the EGR temp sensor and it's right within spec. I also checked the EGR valve, works fine. Closes and seals tight, opens and holds a vacuum, etc. The one part that didn't 100% check out is the thermal vacuum valve (or whatever it's called). It's the little two port valve on the front of the intake manifold that opens at a certain temperature to allow vacuum to the EGR modulator. My ...
