AEM CD-5 and CD-7 Carbon Dashes allow you to add fuel level to your display, and our CAN Sensor Modules make it easy by providing a dedicated input that connects to your fuel level sending device (6 Channel CAN Sensor Module PN 30-2226 and 22 Channel CAN Sensor Module PN 30-2212).
Our CAN Sensor Modules have a maximum Ohms range of 250. If you are using one of our CAN Sensor Modules, you may need to use a resistor to reduce the Ohms range to an acceptable level. The video below explains how to make a connection from most factory fuel level sensors, and how to determine the Ohms range to ensure an accurate reading. Below the video is a calculator that we provide that will help you choose the right resistor if you need to use one to reduce your Ohms range.
For 2008+ vehicles using the OBDII Plug & Play Adapter cable, in many cases the factory ECU will send fuel level to the OBDII port over CAN bus. If it doesn’t, we suggest adding our affordable 6 Channel CAN Sensor Module; It’s a great way to add fuel level and additional pressure and temp channels to your display!
Fuel Level Resistance Calculator
Fuel Level Resistance
| Calculated Resistor Needed: | This is a calculated value based on your Min and Max Ohms measurements. You may select a resistor around this value. | |
| Sensor with Resistor Max Ohms: | This is your calculated max (empty) Ohms resistance with the resistor you selected | |
| Sensor with Resistor Min Ohms: | This is your calculated min (full) Ohms resistance with the resistor you selected | Sensor with Resistor New Range: | This is your calculated Ohms range using the resistor you selected |
