Ford Mistyque 99 v6 2.5l automatico, cortocircuito en cables del MAF

The problem is that by accident the ground of the sensor MAF short circuit with the positive pole of the battery and now it does not start my car and even the led of the safety module blinks as always but when giving the switch contact said led should be on thing that already it does not and I would like to know if there is any other fuse that has to be checked before assuming that the ECU is damaged. I leave more data of my car: ford Mistyque 99 v6 2.5l automatic. Thanks for the help. ATT: Jose Luis.

the fuses are general, there is no fuse per sensor, most likely the protection diode that has the sensor or the voltage regulator of the sensor inside the ECU

Hi. If the Checkengine is not switched on before the engine is switched on, it indicates that the control unit has lost the drive parameters, the alternative would be to remove it and test it on a test bench for this purpose. Salu2.

I explain
the car in contact does not start or start only the lights of battery, oil, brake (stationary) and the chek engine.
and the indicator light (immobilizer or transponder led) lights up normally until the switch is opened and at that point the LED normally stays on but after the incident (short) the led is no longer lit with the switch in position but if it keeps blinking with the switch closed as it always has. thanks for your time and your comments review the internal diodes and regulators ecu
