Hello. Hyundai Sonata 2.0 DOHC 2005
has the sgtes codes
P0115 Engine coolant temperature sensor.
P0110 INTAKE AIR TEMPERATURE Sensor
(both mark in the scanner -40 ° C) and code P0105 Manifest Pressure/Barometric Pressure Circuit previously changed those 3 sensors and the problem remains the same, fan always running and pulls black smoke x excess fuel and remains in open loop or open loop. The input and output currents of the OK sensors. It will be ECU

But voltage reaches the sensors from the ECM you have to see in the vehicle circuit, if those cables of the different sensors do not go with another, which can affect you in the operation of the but, you have to verify the circuit well before changing ECM, because to the improvement the problem is in circuit .....

The first thing you should try is that the sensor's return signal gets well to the ECU control unit since for some reason of false contact or cable cut or linked to another it can be the problem you can also disassemble the ECU and open it and look at the plate The error codes that the ESCAN gives you is like that they were disconnected and the electroventillator is due to the cooling water temperature sensor and the ECU is the one that turns on the same and does not have a temperature record is in emergency.

The problem began after they bridged or touched the O2 sensor with 12V direct battery. (Someone said it was fixed) and the problem began. Revize ok wiring, OK signals. But the ECU does not change to Close Loop or closed loop. Disconnect sensor x sensor and in the scanner there is no change, nor in the operation of the engine. The connectors there is no way to make mistakes

You should first check that these sensors share. But from what I see that sensors is the safest thing that the line they share is the ground or mass as they call it there, since if they fed with 12V the oxygen sensor and it was on the gray line or on another earth you must have burned the internal track mind. The 5V cannot be missing because it would not turn on because it is a main feeding of the ECU and is almost always the same as the sensors. If it is land that is missing directly. In most of ECU and PCM the Earth of the sensors is directly connected to an entrance land.
