Hey guys, I'm Nick with Walker products we're here to talk about exhaust gas temperature sensors or more commonly referred to as an EGT sensor.
Now we have a 2012 Ram 2500 with the Cummins diesel engine it has the check engine light on and we've properly diagnosed that as being a faulty EGT sensor, and we're going to show you how to replace that a little later on.
Here we have several different examples of EGT sensors. The EGT sensor is responsible for reading the temperature of the exhaust, sending this information back to the ECU, which will then use the information to properly control the exhaust after-treatment system reducing harmful emissions. When an EGT sensor fails and the readings become too high or non-existent, this leads to a compromised after-treatment system, resulting in the following conditions:
• clogged diesel particulate filter
• improper regeneration of the DPF
• over fueling
• increased exhaust temperature, which can lead to failure of exhaust components or internal engine components
• check engine light
• idle only state commonly known as limp mode
Ok, we're here under the vehicle. We have located our failed EGT sensor. Now before you disconnect that, you're gonna want to remove the negative terminal of the battery. You always want to do this before performing any type of electrical installation on your vehicle.
Now, we've already done that, so we're going to go ahead and disconnect the electrical connector. Now I'm going to remove the failed EGT. Here's our old EGT sensor, and we have our new EGT. We're going to apply anti-seize to the threads. Now we're going to go ahead and install this. Okay, now that we have the sensors snugged up, we're going to go ahead and use a torque wrench. We're going to torque that down to 33 foot-pounds and we have our torque wrench preset. It's torqued to specifications. I'm going to reinstall the electrical connector. Make sure to reinstall the safety clip.
Okay and that completes our EGT installation. Check back with Walker Products for future tech tips, and please make sure to like and subscribe.
