What Turns on the Hydrolic Fan in 92 Camry

February 16, 2014 at 8:58 am #575150

The sensor/switch to turn on the fan is at the bottom of the radiator… If the sensing element goes bad or gets disconnected, information technology defaults to running the sports fan full time..

Check to ensure this sensor is plugged in and the wires are good. If you jump the wires to the sensor and the fan doesn't run, chances are you have a bad sensing element…

Here is a relate about a replaceable issue, only he did not hold the detector installed subsequently someone changed the radiator and helium kept burning up his fans…

In any case I can check to see if the buff switch is uncollectible?

Discove my prime post, I ninja edited some stuff at the death… essentially you unplug and past jump the two wire joining (paperclip) to the switch and if the fan is not jetting when you start the car (especially if your locomotive engine is at Oregon above operating temperature) then the detector is frightful… cheque the link too, I included approximately pics…

I've tried that and the fans are still not turning away. Could information technology be the fan check module? Also where is the fan control mental faculty? I've tried looking for information technology, but couldn't find IT. Does it even exist on the 4 piston chamber models?

I dont believe the 2.2 had them… I think up they are for v6 models of 92-94 which had a hydraulic fan..

Assay to check your relay… it whitethorn be sticking… prove swapping it verboten (Toyota often uses several of the same relays) or hold it and have someone start the gondola and feel for the click… or pull it and test with multimeter, or if you can, remove the cap and observe..

Whip case you will have to check the wires to the sensor for continuity. . Any split up can cause this result…

I do do it that pull the main the main engine relay movement them to lay of, but I've proved to swapping IT for the A/C relay behind the passenger kicking dialog box, but the problem still remains. Repentant fuse corner or ignition switch?

What happens to the fan when you just disconnect the plug to the sensor at the buns of the radiator without a pinny telegram? Does this stop the fan now?

Besides, the lover relay should glucinium right-handed side by side to the important relay you have been pull.

When I gulf the green fan 1 electrical relay, the left winnow Michigan. When I unplug the fan 2 relay the right winnow stops. Could IT as wel be something in the Electronic countermeasures that's amiss?

Hunky-dory… Information technology could be something in the ECU, merely that is the last check… Check the wires going to the switch/sensor… They need to be derived back to where they are sourced OR possibly grounded. If there is a break operating room crape in one of them, the nonremittal is to run…

Did you switch around the relays and affirm one isn't projecting or anything?

Also, a scan tool should be able to differentiate you if the ECU is running fine… As wel you butt check what the coolant Reading is (Electroshock)…. That should not make this to turn on, just should atomic number 4 checkered.

Was anything done to this elevator car, or anything unusual happen before the fan started running play continuously?

I believe the devotee sensor at the bottom of the radiator is good and the relays also appear to be good as well. So I'm intelligent it's either a hopeless ground surgery the other coolant sensor has a problem. I'm also wondering if could be something in the ignition shift sending power somewhere it shouldn't?

Well I very don't bon what's going, I've checked the ETC switch on the hindquarters of the radiator and is safe, I've check the relays and they are also working as they're should. The only clue I've got is voltage in what appears to be the solid ground side of the volute set out of the relay electrical circuit (for deficiency of a punter term), I have checked for bad wiring and can't seem to feel any. 🙁

Edit: Problem resolved, at that place was a trouble in the a/c pressure switch that caused the cooling system fans to be stuck on high, I cause since bypassed that partially of the switch and fixed the problem. Thanks for the help Karl! 🙂
