Do you have a lab scope to test it with?
Not I dont have a scope, I think that could be the crank position sensor, have a form to test this sensor?

I put a jumper in the conector to check the codes, the number code that show me was the 24(failure of snsor or circuit)the manual that i saw this diagnosis is the haynes techbook, what sensor could be?
