1998 Honda Accord V6 3.0L LX Coupe --- Temperature gauge issue

Hello --- My problem is --- With a cold engine, when I turn my ignition switch to the "on" position, the needle for the temp. gauge moves to the middle position of the gauge. After I start the engine as the engine warms up the needle moves to the middle of the "H" then stops. In an attempt to resolve this issue on my own, I have replaced the instrument cluster and the sensor for the gauge. The part # for the sensor is 37750-PH2-014. The problem still exists. What do you think might be the cause to my problem.
Thank you for your time and ccoperation ---

    Hello Bob - Is the LI after "Bob from" mean " Long Island "?

    Anyway. I'm not sure what you mean. I'm good when it comes to replacing parts that are leaking, noisy, damaged or performing minor diagnosing. I'm not good at electrical. Could you please elaborate more as to what "your solution is" for me. I was thinking that maybe the problem might be in the ignition switch. Please let me know.

    Thanks again ---

    The reason why I asked is because I'm also from Long Island. I lived in many towns but finally settle into a little town on the North Shore of Suffolk County called Coram, which is near Port Jefferson. Are you familiar with that area. Thank you very much for your help. Once I get a copy of the schematic I will get back with you.

    Thanks again ---

I'm guessing that you have resistance in the wire from the gauge to the instrument cluster or that the grounding is bad somewhere. Still have a problem? Leave it alone because you know what is 'right' or insert a resistor in the line to recalibrate it.

    Okay, you've got to find out why the gauge is reading what it is. There are two reasons for this...I just thought of the other one and it might be the issue...many units have something called a 'constant voltage regulator'...this is an item which provides fixed voltage to the gauges. It is possible that yours is bad. I'm not sure where it is. The second possibility is that there is physical resistance in the wiring to the gauge from the sensor. You'll have to trace and measure. Get the schematic for your car. Many libraries have it. Yes, I'm on Long Island and the Massapequa libraries ... among others ... have a full selection.

Why does my temp gauge rise to hot when the van is off - but as soon as the key is switched on it goes back to the cold end of the temp gauge

The gauge is unpowered when you turn the key off, so the needle can go wherever it wants to. When you turn the key on, the gauge gets power and will show the actual engine coolant temperature.

Temp gauge not it the gauge or a sensor?

Check if the wire has not come loose from the sensor, if not, remove the wire from the sensor and hold it against any clean spot on the engine block whilst the ignition is on, (you need someone to be inside the car) if the needle travels all the way to the hot position, you will need to replace the sensor

The temperature gauge goes up when car starts to HOT like its out of calibration. the engine is not overheating

check that the wire to the temp sender unit has not fallen off and is shorting out on the head/block. The power comes from the ignition switch through the gauge down to the sender unit and because the sender is a temperature controlled resistance unit the voltage is very low and so the gauge reads cold . as the temperature heats up , the resistance is decreased and so the voltage is increased though the gauge and the needle reads higher.. Hench if the gauge goes directly to hot on start up the wire is shorting out or the sender unit is faulty.

I have a 1987 mustang GT - the temperature gauge needle does not move from the bottom or cold possition. I tried testing the sensor to ground no change in needle position. when i turn the light switch on...

Hi Randy, If there is no movement when shorting the electrical cable to the body, it seems there is an open circuit between the gauge and sender unit. The problem is wiring. Regards John

When jackaroo 1988 is motoring where does the needle in the temperature gauge normally be

If your temp gauge has only the cold (C) or hot (H) letters then the operating range would be the width of the needle under 1/2 way between c and h. If it remains steady at slightly over 1/2 way that would be just the setting of the gauge. How to get to know where the needle would sit at a specific position in relation to water temp. Do the following
Remove the temp sender unit and attach an earth wire to the body of the unit to earth. Place the sender unit in a container of water up to the threads .Put a mercury thermometer in the container beside the sender unit Apply heat to the container and watch the gauge needle move in relation to the thermometer reading. Operating temp will be about 80 degrees C on the thermometer and that would be about 1/2 way on the gauge.

Temperature needle stays on the hot and doesnt move even when the car is cold?

YOur guage is faulty. Your will need to replace your guage if it stays in the hot position even when your car is off and your key is out of the ignition. If it only rises to hot when you turn the key to the run position, you have a wire between your guage and your temp sending unit that has been gounded out. Usually this happens when a person opens their hood to add oil or perform some minor maintenance on the engine and inadvertantly bumps the sensor or switch or wiring. This causes about 65% of these minor issues people incur, but if it does stay all the way up with your key out of the ignition switch, then you will need to replace your temp guage.

Ive been having issues with my temp gauge sometimes it will move but it will just drop back down randomly and go back up again and sometimes it wont do anything but its never just worked properly sitting...

Its fine, temp needle going up shows that engine is warming up and as soon as the radiator fan starts, temp of coolant drop and this is shown by the temp gauge needle. In most cars (even mine) it stays in middle most of the time unless you are in a traffic with AC on, it will show up more temp. What you can do is get the radiator flushed and coolant changed. Also check the water pump. To do so when engine is cold (in first start in morning), open the radiator cap and ask someone to rev the engine. If the coolant level moves up and down then water pump is also fine.

it may be your thermostat, the gauge on the dash is a dummy gauge, there is only three positions that it sees, dead cold, operating temp, and hot, so even though the needle looks fine it just means it s closer to operating temp then it is to cold,
