Standard Ignition A/C Compressor Connector,Engine Coolant Temperature Sensor Connector P/N:S-550
Standard Ignition S-1923 switch for the 2003-2023 Toyota Corolla and other vehicles is a wiring connector that joins the vehicle harness to a switch or sensor.
An A/C that cuts in and out, a temperature reading that jumps or a check engine light can mean this connector is worn, though the A/C compressor switch or the coolant temperature sensor itself can be behind them, so find the cause before replacing it.
This connector is listed for a wide range of Toyota, Ford and Chrysler models, led by the 1996-2018 Toyota RAV4 and the 1989-2017 Toyota Camry.
This listing holds one connector, and the vehicle takes one.
Is the Standard Ignition S-1923 a brake light switch or headlight switch for the 2003-2023 Toyota Corolla?
No. Standard Ignition S-1923 is the connector for the A/C compressor switch and coolant temperature sensor, not a brake light or headlight switch. If your car isn't named here, check the "Vehicles it fits" section.
Is this an ignition switch for the 2003-2023 Toyota Corolla, including a 2005 model?
No. S-1923 is a connector for the A/C compressor switch and the engine coolant temperature sensor, so it is not an ignition switch. It is listed for the 2003-2023 Toyota Corolla as that connector.
What does the Standard Ignition S-1923 connect to?
Standard Ignition S-1923 is the connector for the A/C compressor switch and the engine coolant temperature sensor. It carries the vehicle wiring to each one.
How can I tell if my coolant temperature sensor connector is worn?
With the engine off and cool, look at the connector for a cracked housing, bent terminals or corrosion. A shop can also test the connector's circuit.
Can I keep driving with a cracked or corroded connector on the coolant temperature sensor?
Have it checked and replaced promptly. A damaged connector can disturb the signal this sensor sends, and a shop can test the sensor and wiring.
