Gauge sitting at a negative number with your key on / engine off? You’re probably at a higher altitude and the electronic boost sensor is affected by atmospheric pressure. To confirm your vacuum source is good, check for suction by placing your finger on the vacuum line coming out of your intake with the engine on. More than likely you are on a bad intake manifold vacuum source or possibly a leak in one of the hoses. Gauge sits at 0 even with the engine on? Check your vacuum line. If it’s sitting at 0 that’s a good sign everything is wired up correctly. Gauge sitting at the top or botton of the scale? Possibly even blinking? The goal here is to have the gauge sitting at 0 with your key switched to the “ON” position and your engine off. You’ll want to find a fused power source using a test light or a multi tester that shows 12v even with the key out of the ignition. This is the memory wire just like in your radio to save your stations. Meaning even when the vehicle is off the red wire is still receiving 12v of power. This means your red power wire isn’t on a constant 12v power source. Gauge works fine but every time I restart the vehicle my settings reset. You may even notice the click sound of the locking mechanism. Give it about 10-15lbs of pressure to ensure it’s plugged in all the way.

Try taking a flat head screw driver to the sensor harness clip while plugged in. It may feel like it’s in all the way and it isn’t pulling out easily with a tug so you assume it’s in all the way. It is really hard to successfully push that harness into it’s connector with just your fingers. The sensor harness has a 2-stage locking mechanism.

The gauge is just blinking or showing “-“ This is probably the most common installation issue.

Premium / Halo / JDM / Premium EVO series gauges: Using about 10-15lbs of pressure should force the clip down. Try pushing down on the harness seat surrounding the pins on the gauge with a flathead screw driver so it makes contact with the circuit board. This can happen if the harness is plugged in and gets yanked on before releasing the locking clip. The plastic clip surrounding the pins can sometimes get pulled up off of the circuit board causing the pins to be shortened so when you plug in your harness the pins can’t contact the wires in the harness. Red and White wires can be together on one accessory source.Įverything wired correctly but the gauge wont power on? Check the harness connection at the back of the gauge.
