Temperature Sensor

The first step to remove the Ambient Temperature Sensor for the HVAC system requires uninstalling the 2GR-FE engine Cool Air Intake Duct Seal. Start by removing the Front Bumper Assembly while keeping fog lights attached when they exist but detach them when they do not. Dismiss the bumper assembly before unconnecting the connector and releasing the clamp on the Ambient Temperature Sensor before removing the sensor.

Service or repair of the Ambient Temperature Sensor / Switch HVAC requires you to remove the Cool Air Intake Duct Seal of the 2GR-FE engine and disassemble the Front Bumper Assembly with optional fog lights. Unplug the connector before you separate the clamp to take out the ambient temperature sensor. Start by mounting the ambient temperature sensor using the clamp before connecting its connector. Install the Front Bumper Assembly following the right procedure for each vehicle type with or without fog lights while concluding with Cool Air Intake Duct Seal reinstallation. Vehicle owners who possess fog lights should perform the steps to aim them properly before checking and adjusting their aim if required.

The first step to remove the Ambient Temperature Sensor requires users to detach both the cool air intake duct seal and the radiator grille. The procedure starts by removing the sensor through disconnection of the connector followed by unfastening the clamp before sensor removal.

When working on the Ambient Temperature Sensor you should disconnect the negative battery cable then wait for a minimum of 90 seconds to minimize the potential of Air Bag and seat belt pretensioner deployment. The system needs initialization before and after disconnecting and reconnecting the negative battery cable during installation steps. The Ambient Temperature Sensor must be isolated by disconnecting its connector followed by sensor and bolt removal. Toward the end of installation the technician follows the exact steps in reverse order of removal procedures.

Service and repair operations on the Ambient Temperature Sensor / Switch HVAC require front bumper removal as the first step. First disconnect the connector then proceed to remove the sensor from the front bumper reinforcement. The diagnostic information available on Heating and Air Conditioning; Testing and Inspection must be used to check the ambient temperature sensor. The last step entails sensor ambient temperature installation.

Disconnection of the connector followed by sensor extraction allows access for service and repair of the Ambient Temperature Sensor / Switch HVAC system. The reverse process for installation creates completion of the service procedure.

The first step to remove the Ambient Temperature Sensor includes disconnecting the cable from the negative battery terminal but certain systems might need initialization following reconnection. The first step involves removing the cool air duct seal then proceeding to remove the radiator grille protector followed by the radiator grille. The completion of ambient temperature sensor removal requires you to disconnect the connector followed by disengaging the clamp.
