How do I know if my temp sending unit is bad?
What Signs May Signal Your Coolant Temperature Sensor May Be Failing?
- Poor Fuel Economy.
- Irregular Temperature Readings.
- Black Smoke from Your Exhaust.
- Your Engine is Overheating.
- Your Check Engine Light is On.
What type of sending unit does the temperature gauge use?
The sending unit is a thermistor. It is exposed on one side to engine coolant. Its variable resistance reacts to changes in coolant temperature: When the engine is cool, as when the engine is off or has just been started, the sending unit’s resistance is at its highest, preventing electrical current flow.
How do you check a coolant temp sending unit?
How to Test a Temperature Sending Unit
- Disconnect the connector from the coolant temperature sensor (temperature sending unit).
- Reconnect the connector to the sensor.
- Disconnect the connector from the sensor again.
- Determine the difference in the two readings.
What does the coolant temperature sending unit do?
A coolant temperature sensor (CTS) (also known as an ECT sensor or ECTS (engine coolant temperature sensor) is used to measure the temperature of the coolant/antifreeze mix in the cooling system, giving an indication of how much heat the engine is giving off.
Where is the temperature gauge on a Fiero?
Temperature Gauge Sending Unit Located on the top corner of the rear cylinder head. This sending unit screws into the corner of cylinder head, near the ignition coil and the valve cover.
Where is the coolant sensor on a Fiero?
It has a one wire connector. Temperature Gauge Sending Unit Located on the top corner of the rear cylinder head. This sending unit screws into the corner of cylinder head, near the ignition coil and the valve cover. Coolant Temperature Sensor (for the ECM) Located below the thermostat housing.
Where is the oil pressure unit on a Fiero?
Oil Pressure Sending Unit Located at the front of the engine and screws onto a metal tube that runs up the front of the engine. EGR Solenoid Located to the right of the thermostat housing, just above the timing cover/water pump.
Where is the cold start injector switch on a Fiero?
This sensor screws into the intake manifold horizontally and has a two wire connector. Cold Start Injector Switch Located next to the thermostat housing. This switch screws into the intake manifold vertically, next to the thermostat housing and the fan switch.
