The CAN-Bus GM Pressure Gauge reads pressure data directly from the ECU through the OBDII CAN network for a cleaner install with no external sensors or extra signal wiring required when supported. Built for 2008+ GM ECUs with CAN pressure output, it delivers real-time pressure monitoring with smooth, stable, and accurate needle movement. Slim housing, solid aluminum bezel, and spin-lock mount keep installation clean and built for long-term use. Made in the USA and backed for life.

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

Key Features:

  • Direct ECU Pressure Data — reads pressure directly from the GM ECU through the OBDII CAN network
  • No External Sensor Required — eliminates added sensor wiring when supported by the ECU
  • 2008+ GM Compatibility — built for supported GM ECUs with CAN pressure output
  • 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 pressure 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

Every Speedhut gauge includes a lifetime warranty* on the electronic circuit board inside the gauge case. It is the core of the gauge — the part responsible for the precision communication that delivers the accuracy and performance Speedhut is known for.

Sensors, wiring, and other external components are covered by an unlimited 5-year warranty.

This combined lifetime / 5-year warranty applies to the original purchaser.
*For your lifetime — as long as you own the gauge — we stand behind it.
Speedhut Inc warrants products to be free from defects in materials or workmanship. This warranty is limited to repair or replacement. Speedhut Inc is not responsible for incidental or consequential damages. Improper use, installation, or unauthorized modifications void this warranty.


Ensure you are using our sensor, most other sensors will not work with our gauges.


With the harness disconnected from the sensor and the gauge powered on, measure the voltage across the red and black wires in the harness at the sensor end. Here you should see 4.9-5 volts. 


Once you have confirmed the voltage, short the red wire to the white wire, this should make the gauge sweep full scale. 


With the harness still disconnected from the sensor, go to key-on or start the car. With the sensor disconnected the gauge should stay at 0 or the bottom of the scale.


If all those turn out normally, next we'll test the sensor. Disconnect the harness from the gauge, and reconnect it to the sensor. Measure voltage between the white wire (signal from sensor) and black wire (ground) and you should see a range between 0.5 to 4.5 volts. You will need to supply power and ground to the sensor while it's disconnected from the gauge. You can use short paperclip pieces if needed.
