how to install transmission temperature gauge on ranger

Remove corrosion from the sensor's electrical terminal using electrical contact cleaner and repeat your test, if necessary. If one or more wires show sign of damage, repair them. Whether you got an unusual reading or not, check that the wiring and electrical connector is free of corrosion.If engine temperature didn't change much throughout your readings, the thermostat is stuck open and you need to replace it.

This will indicate that your coolant sensor is responding to engine temperature.Īlso, make sure the engine reached operating temperature at about 200F (93C) before dropping. If you don't have the reference resistance values for your ECT sensor, make sure that your sensor resistance readings decreased proportionally as the engine temperature increased. Now, compare your figures to the resistance and temperature ratings for your particular sensor listed in your vehicle service manual. You can buy a service manual for your particular car make and model in most auto parts stores or online. If you still have trouble locating the ECT sensor, consult your vehicle service manual. Some sensors are buried under the intake plenum, specially on large trucks, and you need to remove the intake just to gain access to it.Look for a large nut with an electrical connector on top, and two electrical wires coming from the connector - on most modern vehicles - or one wire - on older vehicle models.You can find the thermostat housing by following the upper radiator hose, which connects to the thermostat housing on the engine side. However, one of the most common locations is on or near the thermostat housing. Depending on your particular vehicle model, you may find the sensor mounted on the cylinder head or intake manifold.Open the hood of your vehicle to find the coolant sensor. Wrench (ratchet and socket set, if you need to remove components).On some vehicle models, a bad ECT sensor may upset the transmission, cooling fan, and temperature gauge as well.īut before you blame the coolant temperature sensor for your engine problems, though, use this guide to test the sensor to confirm that you actually need to replace it.On modern vehicles, a bad ECT sensor will upset ignition timing.Or it may cause a constant rich air/fuel mixture, causing an increase in emissions and fuel consumption.It may cause a constant lean air/fuel mixture, causing the engine to stall or idle rough.
