If both fans are working normally... you need to check radiators (both engine and A/C: start with the big one.. could be dirty blocking flow of coolant!)
good luck

The very first thing I would check would be if the battery cables are clean and tight. After that I'd lean towards a bad ignition switch. Do you have a ton of keys on your keyring? wiggle your key while its on to see if you can recreate the problem.

At a certain temperature your fan should come on to take out the heat from the radiator. If this is not happening it could be the cause of the rise in temperature.

MY OIL GAUGE IS GOING ALMOST TO ZERO WHEN I'M IDLING BUT GOES UP TO 40 WHEN I'M MOVING AND WHEN I'M IN PARK.


You have a bad oil pressure sending unit. There is an updated unit available at your toyota dealer parts dept.

2003 sequoia,The oil pressure gauge reads low and floats around. I had an earlier sequoia that the sending unit was replaced for the same problem. Is there a SSC on this problem?


There is no Special Service Campaign on that issue. There is, however, a TSB on that issue, and the fix is to replace the sending unit and the gauge.

The gas guage on my 2003 toyota sequoia stopped working


I would check the fuse first, and if that isnt bad, there is a float in the gas tank that sends a message to the gauge to how much gas is in the tank

Fluctuation on the oil pressure gauge reading


The oil pressure sending unit is a sensor with an internal diaphragm, if the internal diaphragm is damaged , or the line to the diaphragm is blocked you can get this kind of fluctuation on the oil pressure gauge.

The oil pressure value must be read by installing a mechanical gauge near to the oil pressure switch and checking the pressure.

If pressure is ok, replace the sending unit. If there is a real pressure drop, check the oil pump.

If you still get fluctualtion after replacing the oil pressure sending unit, replace the oil pressure gauge.
