Toyota 89422-35010 Sensor, Water Temperature

You can Select Your Vehicle to check if 89422-35010 fits your vehicle.

If the coolant temperature gauge isn't working, check the fuses. If it shows excessive temperature, consult the manual. If it reads HOT on a cold start, disconnect the sender wire. If the gauge drops, replace the unit. If it stays high, the wire or gauge could be faulty. If the gauge doesn't indicate after warming up, disconnect the wire at the unit and connect it to a clean engine ground. Also, reconnect the connector, refill the cooling, and check for leaks.

The Coolant Temperature Sensor has two purposes for your vehicle, it delivers important information to the Powertrain Control Module for engine management and provides information to the temperature gauge on the vehicle's instrument panel. It also detects the engine's coolant temperature and allows for great performance and accurate readings for the driver.

Non-toxic coolant is sold at auto parts stores and requires proper disposal. This applies to 2006 and earlier models. For 2007 and later models, the engine coolant temperature sensor operates the temperature gauge. If the gauge is inoperative, check fuses first. If it shows excessive temperature, refer to Troubleshooting. If it indicates "Hot" on a cold start, disconnect the wire at the coolant temperature sender. If the gauge reading drops, replace the sending unit. If it remains high, the wire or gauge may be faulty. If the gauge doesn't respond after warming up the engine and checking fuses, the circuit or gauge may be faulty. To replace, drain the coolant, disconnect the wiring connector, remove the sending unit, install the new one, and refill the cooling system. Check for leaks and gauge function.

The Coolant Temperature Sensor serves two purposes to the vehicle it is equipped to, it delivers important information to the Powertrain Control Module for engine management and also provides data to the temperature gauge that is found on the vehicle's instrument panel. It also detects the engine's coolant temperature and allows for outstanding performance and precise readings for the driver's awareness.

Monitor the resistance changes with an ohmmeter to ensure specifications are correct when the throttle is completely closed.

The circuit may be open or the gauge may be faulty.

The steps for disposing of used coolant are to drain the coolant and then follow the appropriate disposal methods.

Make sure the ignition key is in the OFF position.

Shut off the engine and connect the wire at the sending unit to a clean ground on the engine. If the gauge now indicates hot, replace the sending unit. If the gauge still does not work, there may be an open circuit or a faulty gauge.

To check the ECT sensor resistance, disconnect the electrical connector and use an ohmmeter to measure the resistance between the two terminals, which should be between 2,500 and 3,000 ohms at room temperature.

Disconnect the electrical connector and carefully unscrew the sensor.

To remove the sensor, depress the locking tabs, unplug the electrical connector, and carefully unscrew the sensor. Before installing the new sensor, wrap the threads with Teflon sealing tape to prevent leakage and corrosion. Installation is the reverse of removal.

The fuses should be checked first.

Depending on the model, either unscrew the ECT sensor from the water outlet housing or, for 2GR-FKS models, carefully remove the retaining clip and pull out the ECT sensor.

To replace the sensor, ensure the ignition key is in the off position and drain approximately one gallon from the cooling system. Disconnect the electrical connector and carefully unscrew the sensor. Wrap the threads of the new sensor with Teflon sealing tape to prevent leakage and thread corrosion. Installation is simply the reverse of removal.

As the magnet turns with the speedometer cable, it causes the lead switch to turn on and off, sending a pulsing voltage signal to the ECM.

The Engine Coolant Temperature (ECT) sensor is a component that monitors the temperature of the engine coolant and relays the information to the Powertrain Control Module (PCM) for engine management and to the temperature gauge on the instrument panel.

As the sensor temperature decreases, the resistance values increase. Conversely, as the sensor temperature increases, the resistance values decrease.

Yes, proper disposal of used coolant is still required.

Further investigation is needed.

Drain about 1 gallon of engine coolant, ensuring that the engine is completely cool before doing so.

A faulty ECT sensor circuit will trigger a diagnostic trouble code.

Disconnect the electrical connector and carefully unscrew the sensor.

The oxygen sensor monitors the oxygen content of the exhaust gas stream, producing a voltage output that allows the ECM to adjust the air-fuel ratio.

These models are equipped with an upstream O2 sensor (before the catalytic converter) and a downstream O2 sensor (after the catalytic converter).

plug is part of wiring and harness for the engine.
