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
  • Stepper Motor Precision — smooth, accurate pointer movement
  • Made in the USA — backed by a lifetime warranty
Important OBD2 CAN-Bus Notes
  • Supported Data Required — vehicle must output CAN temperature data through the OBD2 port
  • Dedicated OBD2 Connection — no other devices can share the port
  • Data Only Through OBD2 — separate power and lighting wiring required
  • No Analog Input Support — not compatible with analog senders or raw signals
  • IPX6-Rated Protection — sealed against heavy spray; not for submersion
