What causes the temp gauge to peg Hot?
What causes the temp gauge to peg Hot?
When my car is running, the temp gauge goes and pegs hot, even if the car is cold. I dont know if its a coincidence that I just changed my plugs or what, but Id like the gauge to read proper. What would cause it to peg hot??
Is the temperature gauge hot but not overheating?
Temperature gauge hot but engine is not overheating. have the same problem? Have you checked your coolant level lately? I would start there. helpful? The temperature gauge can show hot without the engine overheating which still means that is a problem. To tell for sure if it is a gauge or a cooling system problem use a
Why does my car’s temp gauge read erratically?
A small air pocket around the sensor can have really erratic effects on the “gauge” temperature. Especially if the sensor is in the very top of a housing, where air may accumulate. Some thermostat housings have a small bleed screw to make this easier.
What to do if your temp gauge goes to zero?
Turn the ignition on, but don’t start the car. Give what you say above, the temp gauge should read half. Now unplug the sensor. If you have a bad sensor, the gauge will go to zero. the gauge will stay the same. Well the FSM points just like you said to the passenger upper rear for this sensor.

When does the car temp gauge go hot?
But if it is connected, the needle will rise and peg out to hot when the car warms up, but it started half way up the gauge. So checking resistance between the yellow/red male pin and ground.

What causes a temp gauge to go nuts?
If that’s the plug in the top picture, you likely have a wiring fault somewhere between the instrument cluster and that plug. It looks like that wire runs a short distance forward and joins a fat (1″ OD) cable then runs in the fat cable back to the firewall, across behind the engine, then through the firewall.
What does the temperature gauge do when you turn on the engine cold?
What does the temperature gauge do when you turn on the engine cold. and ground with a cold engine and report back. IIRC (check the colors, be careful, there’s also a light green with a red stripe wire in there). And let us know which wire it was, the one closest to the block or farthest from the block (it’s NOT the middle one).
What causes the temp gauge to go to zero?
Car cold, ignition on, you would expect (given your most recent experience) to see the gauge at half. Unplug the sensor, gauge will go to zero with a bad sensor. Same problem today, car starts witht he needle at half, then warms up and pegs out.
