Well my temp gauge goes to HOT , asoon as I open the ignition * not start *

after I start the car . the power FC commander tells me the degrees in Celsius started at 22 degrees and I shut the car off at 88C ,


so I mean thats working ..

BUT the gauge on the gauge cluster seems to be grounded somewhere and read HOT as high as it can go the whole time .

not I'm trying to figure out if there is a short ..

or if the sensor is bad ..

but unless the power FC has its own dedicated temp sensor .. then that temp sensor cant be bad since it was working with the Power FC.. and the short is in the front harness .

 

Yes the ECU gets the temp off a different temp sensor than the gauge. The gunge sensor is under the Oil pedestal.. Hope that helps

 

water temp sensor for dash gauge is on driver side rear iron, below oil filter.

water temp sensor for PFC is behind water pump housing, so power fc has it own dedicated sensor.

 

yes thanks alot both of you guys. I guess I need to source a new sensor .

 

yeah its behind the thermostat housing on top. Green connector. Thats for ecu sensor. The gauge is a one wire sensor. Id check to see if you have wiring problems first before replacing sensor

 

What are the 2 sensors for on the back of the water pump housing, one is the ecu temp, but what is the other?

 

^ Fan Thermoswitch. You are talking about the sensor with one wire correct?

Yeah, they are right next to eachother on the back of the housing. I'm just trying to figure out what I can get rid of.
