Question about 2001 Dodge Ram 1500 Truck 2WD

1 Answer

Inaccurate temp gauge

I have a 2001 Dodge Ram with a 3.9L engine. The temperature gauge will only read the engine temp at idle. Once going down the road, the needle on the gauge will bottom out completely until the next time the truck is stopped. I've replaced the temp sensor twice-no help.

Oil pressure drops when im at lights,but goes back up when i go,no knocking noises,n regular oil changes,what should i do


First hook up a mechanical pressure gauge to get a true reading--you may just have a bad sender. If pressure is less than 10 to 15 psi at hot dead idle, tell us how many miles on engine--what oil you are using--how often you change it. I have sometimes gone up one notch on thickness of oil on worn engines and run them many more miles.

The temperature gauge reading of my nissan admax 2001 model is always too high. but im not experiencing overheating. what do i do?


If your temperature gauge is reading too high, it can only be one of two things: The engine is overheating or the gauge is "lying" to you. I would recommend first taking the temperature of the cylinder head with an infrared thermometer to determine which one it is. If the engine is actually as hot as the guge says it is, then you need to check your cooling system. If the engine is not as hot as the gauge says it is then you need to diagnose and repair your gauge circuit. (most likely an inaccurate temperature sensor)

98 Camaro LOW running temp. I just recently purchased an all original, terrific running 98 Camaro Converible with only 86000 miles on it. Everything seems great and I've been driving it for weeks with no...


I would suspect either the temp guage or the coolant temperature sensor being inaccurate. The new thermostat is probably working good, or else you wouldn't have a very warm heater. If you have electric radiator fans, you might check to see if they are running all th time. Electric cooling fans should only come on when the temperature sensor reaches a predetermined coolant temp, or when the a/c or defroster is turned on. If the fan runs all the time, the engine would not reach normal operating temperature.

The temperature gauge on my 1999 Dodge Ram 1500 is not working. The temperature sensor and the thermostat have been replaced.


Check the gauge by holding in the trip odometer reset button and turn key to run,hold button for 10 seconds this will iniate a diagnostics on all the gauges,and lights if gauge doesn't move during this test replace gauge,if it does move then check the wires on the plug at the engine coolant temp sensor (ects) you can check the sensor by using a ohms meter by unpplugging it and check ohm's or resistance when cold and then start engine as the engine warms up the ohm's reading should gradually lower as the sensor is a thermister and as it warms up the resistance will drop.

2001 dodge stratus engine temperature gauge spikes occasionally


Look for a loose connection to the temperature sender unit on the motor.
If all connections OK, you may need a new temp sender unit.
