Frequently Asked Questions
1Why doesn't the pointer return to zero when the gauge is off?
These gauges use stepper motors, which require power to reset to zero. It is completely normal for the pointer not to return to zero when the vehicle is off. Once powered on, the gauge will self-calibrate and return to the correct position.
2Does the Air Fuel Ratio Gauge come with an oxygen sensor?
No, the Air Fuel Ratio Gauge does not include an oxygen sensor. You will need to use a narrow band oxygen sensor with an output voltage of 0–1V, which must be purchased separately and installed in your vehicle's exhaust system.
3What thread size does the EGT sensor use?
The EGT (Exhaust Gas Temperature) sensor included with the Exhaust Temperature Gauge uses a 1/8 NPT thread size. Please verify compatibility with your exhaust system before installation.
4What thread size do the water temp and oil temp sensors use?
Both the Water Temperature Sensor and the Oil Temperature Sensor use a 1/8 ZG thread size. Please check your vehicle's sensor port before installation to ensure a proper fit.
5What is the voltage range supported by the Voltmeter?
The Voltmeter supports a measurement range of 8V to 18V, making it suitable for monitoring standard 12V automotive electrical systems. It can detect overcharging or undercharging conditions in your vehicle's battery.
6Do all the gauges come with installation instructions?
Yes, every gauge in this product line includes an English manual in the package. The manual provides step-by-step wiring instructions and installation guidance to help you set up the gauge correctly.
