The CAN-Bus GM Temperature Gauge reads temperature data directly from the ECU through the OBDII CAN network for a cleaner install with no external sensor required when supported. Built for 2008+ GM ECUs with CAN temperature output, it delivers real-time temperature monitoring with smooth, stable, and accurate needle movement, while a settable warning light adds a clear visual alert when temperatures move out of range. Slim housing, solid aluminum bezel, and spin-lock mount keep it built for long-term use. Made in the USA and backed for life.

Track-Tested. USA-Built. Backed for Life.

Key Features:

  • Direct ECU Temperature Data — reads temperature directly from the GM ECU through the OBDII CAN network
  • No External Sensor Required — eliminates added temperature sensor wiring when supported by the ECU
  • 2008+ GM Compatibility — built for supported GM ECUs with CAN temperature output
  • Settable Warning Light — clear visual alert when temperature moves out of range
  • Microprocessor-Driven — real-time accuracy
