“My Scan Gauge doesn’t show EGT! Is it broken?” John exclaimed, a frustrated frown etched across his face. He was working on his prized ’98 Subaru Impreza WRX, prepping it for an upcoming track day. John, like many car enthusiasts, relied on his Scan Gauge to monitor his engine’s vitals, but the lack of EGT readings had him stumped. Does this sound familiar? If so, you’re in the right place.
Understanding EGT and Why It Matters
Before we dive into whether your Scan Gauge can monitor EGT, let’s break down what EGT is and why it’s crucial for car owners, especially performance enthusiasts.
EGT stands for Exhaust Gas Temperature. Think of it as your engine’s internal thermometer. It measures the temperature of the exhaust gases as they exit the engine cylinders. Monitoring EGT is like keeping a finger on the pulse of your engine’s health.
Why is EGT important?
- Engine Safety: Excessively high EGTs can spell disaster, leading to detonation, pre-ignition, and ultimately, catastrophic engine damage.
- Performance Optimization: For performance junkies, keeping EGTs within an optimal range can unlock horsepower and improve fuel efficiency.
So, Can a Scan Gauge Monitor EGT?
The short answer is: not directly.
Scan Gauge tools are incredibly useful for monitoring a wide range of engine parameters, but they don’t come equipped with a dedicated EGT sensor. They primarily read data from your vehicle’s OBD-II port, which doesn’t typically provide EGT information.

Don’t Despair: Alternative Ways to Monitor EGT
While a Scan Gauge may not directly monitor EGT, there are other effective methods to keep tabs on this crucial metric:
-
Dedicated EGT Gauge: This is the most accurate and reliable method. It involves installing an EGT sensor in your exhaust manifold and connecting it to a dedicated gauge.
-
Aftermarket Engine Management Systems: High-end systems like AEM Infinity, Haltech, or Motec offer comprehensive engine management, including EGT monitoring, but they often come with a heftier price tag.
When in Doubt, Consult a Professional
“Monitoring EGT is like reading your engine’s mind,” says automotive engineer Emily Carter from Bosch Automotive. “It’s not just about numbers; it’s about understanding what those numbers mean for your engine’s health and performance.”
If you’re unsure about monitoring EGT or interpreting the readings, it’s always best to consult a qualified mechanic or automotive specialist.
Frequently Asked Questions about Scan Gauge and EGT
Q: Can I add an EGT sensor to my Scan Gauge?
A: Unfortunately, no. Scan Gauge tools are not designed to accommodate additional sensors.
Q: What are some signs of high EGT?
A: Loss of power, detonation (knocking), and glowing exhaust manifolds are telltale signs of high EGT.
Q: How can I lower EGT?
A: Ensuring proper air/fuel ratios, upgrading your cooling system, and avoiding prolonged high-load situations can help lower EGT.
