TEMPERATURE

It seems to me that cables are invested and also check the mass connections

Greetings Gustavo, I agree with visitor and mathiew that the oil and temperature pressure cables are inverted, basically explaining each sensor, the oil pressure goes to ground while the engine off, when you turn on the engine the pressure of the oil disconnects the sensor from the ground, the temperature is an NTC type resistance (negative temperature coefficient); In other words, when the temperature increases, its resistance decreases, as this resistance is low, it is able to turn on the light of the witness, which can be the oil pressure, and obviously if you put to land the temperature cable goes to the limit the clock (cold motor-> High resistance, hot engine -> low resistance), let us know how it went, greetings.

Thank you very much friends, I appreciate them, you could recommend some solution since an electric part is not my strong I am learning I hope to help me (apologize but the installation never touched anything I did all repairs .. ¨¨ And something else removes the thermostat by precaution and if the oil of the oil is turned on ”I hope your valuable help that God bless you thank you

Greetings Gustavo, with this type of sensor in your car model No problem exchanging the connections as they already commented, there are times when the engine is mounted and the electrical part is connected, one contact connections can be confused (such as the temperature sensor and oil pressure), the same terminals were previously used for different things, they are currently worth the shape and color of the "splices" to avoid these errors. Try exchanging them and tell us.

I believe that your problem lies in the land cables in your over that they made to the vehicle, if they painted it the cables that go to the chassis want make bad contact, if they installed something like a new radius, low, amplification will depend on what they did to shorten the search field.
