What does the throttle body temperature sensor do?
A throttle body temperature sensor is a critical component to your vehicle’s fuel injection system. It measures the temperature of the air/fuel mixture entering the fuel injection system on your vehicle’s engine.
How long do throttle body sensors last?
The average lifespan of a throttle position sensor is just over 80,000 miles, though some will last for the lifetime of the car. If a TPS is suspect, a professional repair facility will perform electrical testing on the sensor.
When to replace a throttle body temperature sensor?
A throttle body temperature sensor may wear out over time and should be replaced by a professional mechanic if necessary. ## symptoms of a failing throttle body temperature sensor include: 1. Poor Engine Performance
What should the temp of the coolant sensor be?
Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function.
How does the ECU monitor the engine temperature?
To get an accurate reading of the current engine temperature, the ECU sends a regulated voltage to the CTS. The resistance of the sensor varies with temperature, this is how the ECU can monitor temperature changes.
Why does my car coolant sensor keep dropping?
If there is a leak in the engine bay and the oil enters the engine block, the coolant will get contaminated, causing a problem to the ECT sensor. The coolant system of the car does not need constant refilling. However, if the coolant level is dropping frequently, there might be a leak which should be fixed immediately.
How is the coolant temperature sensor on a car controlled?
A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm. Get a wiring diagram and find out what ohms you should have at a specific temperature to check the function. You can use a Digital multimeter. to check the Ohm between the pins.
What should coolant temp be when engine is hot?
With a good OBD2 code reader, you can also check the live data and the parameters of the CTS sensor. Check that the temperature value of the CTS is around 80-90c when the engine is hot. A lot of engine coolant temperature sensors have two wires and the sensor is controlled by Ohm.
What are the senses of the ECU engine?
Within each of these senses there are a range of different inputs possible. The ECU has its senses as well: MAP (Manifold Absolute Pressure), TPS (Throttle Position Sensor), MAF (Mass Air Flow), ECT (Engine Coolant Temperature), IAT (Intake Air Temperature), Tach, O2 (oxygen sensor) and other inputs.
How can I tell if my coolant temperature sensor is bad?
To diagnose the coolant temperature sensor, you need a repair manual for your car model to find what measurement values you should expect from the coolant temperature sensor. Connect an OBD2 Scanner and look for related trouble codes. Check the live data to see the temperature from the sensor.
