Justy Idle Problems
Posted 29 January 2004 - 12:46 PM
1. Temperature guage warms to 1/4 to C and stays there at all times. Unless the engine is idleing for a long time...then shoots to H.
2. Fan never turns on.
3. No check engine light.
At this point, I am stumped. Car runs fine except for these problems. I am hoping somebody out there has seen this before.
Car in question:
91 Justy EFI 4wd.
Justy w/4wd + Hakkapalittas= Snomobile with heat!

Check the fuel injection thermosensor for dirty contacts or a faulty unit
There must be an IAC (Idle air control valve), sounds like it is wanting cleaned as it is attempting to set the proper idle.
Sorry I can help much, one of the Justy Boyz, surely will come to the rescue.

#2.. check the connections that are on the fan thermoswitch that is on the radiator.. usually you can unplug the 2 wires and short them together to get the fan to turn on.. that will tell you that the fan works but the switch is bad.. then replace it.
#3.. is there a reason it should be on? you should see it come on when you initially turn the key on, otherwise it should stay off.. if its not coming on at all, it could be a burned out bulb..
just my opinions on those problems..
on the idle i have no idea..
