Scion Temperature Sensor

37 items

Automotive temperature sensors measure conditions in systems such as engine cooling, intake air and battery monitoring. Choose by the measured system and vehicle application, then compare mounting, terminals and connector shape. Similar plugs do not establish the correct signal or calibration for a different circuit.

Automotive Temperature Sensor Types

Automotive temperature sensors send measurements to a gauge or control unit. The collection includes coolant, intake-air, intake-manifold and battery temperature sensors for selected applications.

Identify what is being measured and where the sensor is installed before choosing a replacement. A connector that looks similar does not make sensors for different systems interchangeable.

Choosing And Diagnosing A Temperature Sensor

Match the vehicle application, sensor function, mounting and electrical connection. Some sensors screw into a housing while others use a different mounting arrangement. Terminal count and connector shape are useful details, but they do not establish the correct signal or calibration for the circuit.

Treat an overheating warning as a possible cooling-system problem requiring prompt attention. Do not dismiss it solely because the sensor is a possible cause.

Frequently Asked Questions (FAQ)

Can an intake-air sensor replace a coolant temperature sensor?

They measure different things and are used in different locations. An intake-air sensor reports air temperature to engine controls; a coolant sensor reports the temperature of the cooling system. Select the part intended for the affected circuit.

Does a temperature sensor always operate the dashboard gauge?

The output depends on the vehicle's wiring and controls. One listed one-terminal coolant sensor is specified for an application with a gauge, while other sensors provide information to an engine control unit. Match the intended circuit, not only the sensor name.

Are one-, two- and three-terminal temperature sensors interchangeable?

The number of terminals reflects a product's connection, but it does not identify every signal or the sensor calibration. Current coolant-sensor listings include examples with one, two and three terminals; use the sensor specified for the vehicle and system.

What else can cause an incorrect temperature reading?

A damaged connector, wiring fault or an actual temperature-control issue can affect the result. Check the sensor connections and wiring; a thermostat fault can also produce a coolant-temperature-related code.

What does a battery temperature sensor measure?

It measures battery-related temperature for the vehicle's electrical management on equipped applications. It is not the engine coolant sensor, even if both products are grouped under temperature sensors.
