Is this a fuse or what??

I don,t know where the sensor is. I was look under the truck today and see what I can find. We need the truck now because our Van is down and the truck is all we have left.

The truck water temp gauge is showing hot with the motor being cold. So whats wrong?? Is it the sending unit? or a fuse someplace? After looking all over the net I see the truck has a sending unit and a sensor for the EFI. I am talking about the water temp gauge showing hot when its cold. The truck is a 1988 Toyota pickup 4x4 with the 22re motor Thanks Don and Barb Last edited by Tcloud; 01/01/11 02:01 AM.

Just dug a bit in the FSM; your water temp sensor is on the rt side of the head; closest to the fuel pump closeout plate (where a fuel pump would be mounted for a carbie). The chart is a graph, so it looks like at about a coolant temp of 68F that your resistance should be around 2K ohms. You can check that quick with a meter before going after other parts, at least. You don't have a fuse for this problem. http://www.walkablecommunities.org/ Democracy is two wolves and a lamb voting on what to have for dinner.

I havent fixed it yet , but from what I have found is, apparently , there are 3 screws that hold the "guage" into the main dash pod . 1 of these is a ground screw , and apparrently over time can loosen . although I have not taken mine apart to repair it , and cant confirm this .. if you have some time , you might just tighten these back up and let me know .. . 86 4x4 , fiberglass bed , 1/2 doors , hood, etc.. 84 Custom 2WD 400HP supra suspension , full frame 83 Trekker SR5 NEW Trekker forum Re: 1988 Pickup Temp gauge help [Re: CJM] #1016593 01/01/11 08:27 PM Joined: Jun 2008 Posts: 29 Oak Hills Calif T Tcloud OP Getting the Wheeling Fever CJM Mine is always showing hot.
