Valve motor problem
Valve motor is broken, or blocked by a particle. So engine can’t recognize its position.
Disassemble and check, replace if needed.
Valve position unknown
How to detect:
gpio_pin_get IDS_VALVE_POS1
returns 1
AND
gpio_pin_get IDS_VALVE_POS2
returns 1
How to fix:
This can be due to misalignment of the disk on the valve shaft and may require
replacement of the pinch valve (try manually cycling the valve using tcl commands to
openink, openair, & closed and see if the appropriate position is returned). Before
attempting to change out the valve, de-power the engine, then remove and reinsert all
electrical connectors at the valve. If this fails to correct the problem, then the valve needs to
be replaced.
