Can you post the engine wiring diagram for your engine?

Does the factory wiring supply the sensor with +12V or +5V?

How do you have the jumpers set on the board?

Jumper settings are jp2 halll,jp4 on other open.
I test it with power suply it is 12v.cant figure car wiring diagram.
I tried all 3 wire as signal change polarity.my boards some components not installed but everything is ok about ignition input.just sp721 and ignition out components missing.

If the Hall sensor is 12V it will kill the Arduino input, needs to be 5v or less.

If the Hall is 12V, you can use the 10K pullup jumper if it's active low, the resistor acts like a divider.

the signal wire will need a 5V pullup voltage. it will switch to ground

Solved with replace hall sensor
