What PID’s Are Most Important When You Drive Your Diesel?

Knowledge is power. With the correct information and knowledge, you can diagnose, prevent or maintain your diesel engine. The fuel you use is the only thing that resembles your diesel to your grandfather’s 1989 12-valve Cummins pickup. Your truck can access a vast amount of information about its engine’s performance with technology that is constantly changing.

The EZ LYNK Auto Agent is cloud-based and connects directly via wifi to the device.

EZ LYNK’s Auto Agent 2.0 can be a critical part of keeping your diesel engine running for hundreds of thousands of miles. The Auto Agent connects directly to your vehicle’s diagnostic port. It can display multiple gauge configurations that are useful for daily driving. You can also access the mobile app to view and clear diagnostic trouble codes. The EZ LYNK App is wifi-based and streams data seamlessly from the Auto Agent to your Android, iOS, or tablet.

PID’s (Parameter identifications) are the key to troubleshooting and diagnosing problems. You will encounter an issue if you have had a diesel truck for a long time. These problems can sometimes occur at the worst times. However, with Auto Agent, you can access your PID data and check for any trouble codes that your truck may have. You can send these data points to a technician for more detailed interpretation and up to 30 minutes of data log. You can choose to have the technician be at your local shop or the dealership of your choice. You have complete control over when and how your truck is being repaired.

Auto Agent is connected to a cloud so that any information can be quickly sent or received. If the technician requires any changes, you can do updates via the unit. This saves time for the user and allows them to do the updates at their convenience rather than schedule a visit to a store dieselarmy.com

Programmable data screens that can be customized are simple to use and allow you to keep an eye out for the parameters that matter most to you. Two common data points that give you a glimpse into your engine’s performance are boost pressure and exhaust gas temperatures. A turbocharger problem such as a faulty actuator or a boost leak can be lower than a standard boost.

Higher than normal EGTs may indicate fueling problems or overwork conditions. Stock trucks have average EGT values between 30-35 PSI, and modified trucks can see much higher. EGTs should not be exceeded at 1200-degrees.

You can also access other data points like transmission temperature, engine coolant temperature, and engine oil temperature. For those who tow heavy or frequently with their trucks, these parameters are vital. Transmission life can be extended by keeping temperatures within normal operating ranges.

Although the engine coolant temperature should be maintained, many people neglect to check their engine’s oil temperature. The oil cooler helps keep the oil temp under control. However, if the oil gets too hot, it could indicate that the engine has been overworked. These issues can be addressed by changing your driving style or sending a data log to confirm proper operation.
