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.

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??

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.

How to fix the faulty temp gauge on a Pajero / Shogun?

1. Turn off the engine, turn off the switch (you may disconnect the battery, but it is not really needed), lower the steering wheel to the minimum location. 2. Remove those 2 bolts and carefully pull that plastic cover out:

What to do if your temperature gauge is pinned Hot?

If you measure around this value (or definitely not near 140 Ohms) with a cold engine then the unit is faulty and needs to be replaced. A quick test is to disconnect the lead from the sending unit, turn on the ignition and observe the temp. gauge. If it registers ‘zero’ then most probably the sending unit is faulty.

What should the temperature gauge be on a hot engine?

With a hot engine it should measure 30-50 Ohms. If you measure around this value (or definitely not near 140 Ohms) with a cold engine then the unit is faulty and needs to be replaced. A quick test is to disconnect the lead from the sending unit, turn on the ignition and observe the temp. gauge.

What should I do if my temp.gauge says zero?

Is the temp sending unit good or bad?

The original Sending unit appears to be bad. No readings from it Hot or Cold. The newer one gave me some screwy readings. At room temperature the new one shows 52 Ohms, at 210 degrees it shows 8 Ohms. It should go the other way. I wonder if this is a bad part or I have the wrong one of these as well. Have to go to Plan B now.
