    Water Pressure on Smartcraft

    I recently installed a Smartcraft Monitor on my 250XS and everything works great, except the water pressure, it's reads 0.0. I have a analog Water psi gauge that shows I have good pressure and I have no alarms, but the SC reads 0.0. What do I need to do to get the smartcraft monitor to display the water pressure? I have have tried switching the Pitot sensor with the water pressure sensor to see if it will read pressure, but reads 0.0 as well. I dont think the pressure sensor is bad, I do not no what else to do...

    Have you disconnected the gray tubing from the Block (water) pressure sensor (on the coil plate) to confirm there actually IS water pressure at this hose????

    If yes- have you confirmed that the water pressure data item is enabled in the System Monitor's setup/calibration?

    Yes, there is pressure at the hose. How do you enable it? It is turned on in the "cal1" mode...

    The Value shown should be "on" or "1 (digit ONE)".

    If that is how it is, I would recommend that you have someone VERIFY the water pressure shown in the "Block Pressure" data line (with either the Computer Diagnostic System, or with a DDT). This would help to determine if the problem is in the sensor & ECM, or if the problem is actually in your Smartcraft Instrument.
