Strange Readings from RT Sensors and Dash2
Posted: Mon Oct 02, 2023 9:03 am
Hi everyone,
Looking for some help with my Dash2 and RT sensors, which are giving me some strange and obviously incorrect readings.
My setup is the Dash2 with water temp, oil temp and oil pressure sensors from RT and I've even got the wires and connectors from RT with the built in resistors in an effort to make things easy for myself. All 3 sensors have the red wire connected to the 5V reference, white wires connected to the various analog inputs, and the black wires have a good ground connection. In the software I have selected the standard sensors, and sent the configuration to the dash2. Should be all good right?
However, I'm getting 137 degrees on both temperature sensors and -18 on the pressure sensor, all when the engine is cold so should read ambient temperature (around 18 degrees C) and zero pressure.
What is going wrong?!
