Where is the map sensor on a 1990 honda accord

usually idle that goes up and down is cause by a bad "idle control valve" located near the throttle body. Needs to be replace.

SOURCE: 1990 Honda accord horn problem

Horn fuse should be located in the fuse box under the dash on drivers side kick panel. If fuse is good try replacing the horn itself, it might be bad due to the age of the car. They are located behind the front bumper on the left and right side.

SOURCE: Honda Accord Map Light bulb

the cover is removed straight down, slowly working it with a thin tool or butter knife. WD40 to front and rear edge (there's nothing medial or lateral). The cover has 2 Y clips on each side, one about half way, and one that clips straight off of the hinge post. There are no "tabs". It will eventually unclip straight down. Then can replace with a DE3175 LED bulb (V-LEDs.com)

Hi there,

Firstly - DO NOT run engine, when guage reads hot, as this will cause costly damage to head gasket & alloy engine head.

The fact that guage takes 1min to read HOT, would confirm the guage IS working properly.

So, other components which are likely to cause hot readings (in this order) are:

- lack of coolant (or leakage somewhere): is there sufficient green coolant at the correct level? Top up mixture to correct level. Repair any leaks.

- collapsed radiator hose: when engine is cold, start engine, then quickly watch both upper & lower radiator hoses to see if either begins to flex inwards (collapse). Replace if either hose is collapsed.

- bad/incorrect thermostat rating : when replacing thermostats, you must ensure it is of the SAME temp rating (they all differ).

- Incorrect Temp sensor rating: the ratings of this sensor must be within manufacturer's spec's.

- bad waterpump: the engine relies on the waterpump to distribute the coolant throughout the entire system. If waterpump is faulty, coolant will not flow quick enough, causing overheating.

If you still believe all of the above components are OK, then have your cooling system "pressure tested". This test should be done, before looking further at other electrical components.
