Overview of Delphi TS30312 Exhaust Gas Temperature Sensor

The Delphi TS30312 Exhaust Gas Temperature (EGT) Sensor is designed for precise temperature monitoring in Mercedes-Benz E320 and E350 models. Engineered to withstand high temperatures up to 850°C, this sensor ensures reliable performance in demanding emission control applications.

  • Maximum temperature rating of 850°C for durability
  • 24.96-inch wiring harness length for flexible installation
  • Threaded nut mounting type for secure fitment
  • Blade terminal type with 2 terminals (female) and oval male connector
  • Positioned before the turbocharger, rear for accurate exhaust gas temperature readings

Detailed Product Description

The Delphi TS30312 EGT sensor is a critical component in emission control systems, specifically designed for Mercedes-Benz E320 and E350 vehicles. Its robust construction allows it to operate reliably at temperatures up to 850 degrees Celsius, making it suitable for monitoring exhaust gases before the turbocharger. The sensor features a 24.96-inch wiring harness, providing ample length for installation flexibility. The connector is oval-shaped and male, paired with female blade terminals, ensuring a secure electrical connection. The sensor mounts using a threaded nut, which facilitates a stable and vibration-resistant installation.

Applications and Problem Solving

  • Monitors exhaust gas temperature to prevent turbocharger damage
  • Helps maintain optimal engine performance and emissions control
  • Detects overheating conditions to protect exhaust system components
  • Supports compliance with emission regulations by providing accurate temperature data
  • Prevents sensor failure due to high-temperature exposure

Installation Notes and Tips

When installing the Delphi TS30312 sensor, ensure the sensor is positioned before the turbocharger at the rear, as specified for your Mercedes-Benz E320 or E350. Use the threaded nut mounting to secure the sensor firmly, avoiding over-tightening which could damage the sensor or mounting threads. Verify the wiring harness length of approximately 25 inches is sufficient for your vehicle’s routing requirements. Confirm the oval male connector mates properly with the female blade terminals to ensure a reliable electrical connection.

Quality Assurance and Warranty

Delphi manufactures the TS30312 sensor to meet strict quality standards for emission control components. The sensor is built to endure high-temperature environments and maintain accurate readings over time. While specific warranty details should be confirmed at the point of purchase, Delphi typically offers coverage against manufacturing defects to ensure product reliability and customer confidence.
