That such in the forum I hope and can help me not to do an innesary expense since there is a bit of crisis in my pocket, the problems are described below:
first of all when I disconnect the connector of the coolant temperature sensor of the coolant turn on the fans, but if I connect it again they go out the fans of the radiator (because the two fans are connected in parallel with a single relay) Check the voltage of a terminal with respect to the ground and gave me approximately 5 volts, the other terminal checks continuity with land and I mar Latoso to be connecting and disconnecting every time I turn on and turn off the car ..
Another doubt is that when the car heated on one occasion I realized that I did not turn on the fans and then I mention above it connects it almost directly to the battery, check the cables from the relay to the fans because it marked continuity or as if it were short of the positive and the negative of the fan, until it reaches the ventilator. Eureka the fans caused me that continuity, it is normal for the engines to continue continuity because I understand that they must offer some resistance or impedance and I did not give me anything I marked continuity and I do not know if this is correct, but the curious thing is that if I connect the direct fans to the battery, the condemned fans turn on ???? If you can help me with this problem ???
Check the opening sensor of the strangulator that is the TPS (Throttle Position Sensor), which as it acts as a potentiometer, the total resistance of the ends of the ends gave me 12 kohms and then check him with the inmedium terminal and looked at how the resistance varied up to 2.3 kohms with the butterfly fully open, and check the voltage of each terminal and gave me the voltage of each terminal The first 12 volts as the battery the second almost 11 volts and the third the check with respect to the body of the body and gave me correct, according to a manual that I have, I do not know if this sensor must have the resistance I mention before because it does not specify how much resistance should the sensor have ??????
The other is due to the warm -up of the car I do not know if the thermostat is evil since they told me that if the hose where the thermostat was not hot is that the thermostat is bad and does not let the coland flow to the radiator, I do not know if it is true because it checks the hose that goes from the radiator to the engine and was hot (That is where the thermostat is lodged [in the motor part]; I think) to check this I leave it about 5 minutes in idle without correcting the car I think it was enough for it to reach its operation temperature ???????????? If you can tell me if this was correct or not?
And finally how important the oxygen sensor for the ignition of the car is because I think this is also bad, since it checks the sensor resistance between terminals 1 and 3 and gave me a resistance of 10 ohms and already on the dive volts already at operation temperature ????
Thanks in advance for your help
