Cold Start Injector Time Temperature Switch for Toyota 4Runner Camry Corolla Pickup and More OE#89462-30011

When to Replace The cold start injector time temperature switch should be replaced in the following situations: - Difficult Cold Starts: The engine shows difficulty starting or requires multiple attempts to start when cold, possibly due to the switch failing to accurately detect temperature, causing the injector to malfunction. - Decreased Fuel Efficiency: The vehicle's fuel consumption increases noticeably, especially during cold starts, may be improved by replacing this switch. - Diagnostic Codes: The vehicle's electronic control unit (ECU) displays fault codes related to the cold start injector time temperature switch. Detection of fault codes related to cold starts (e.g., P0115, P0116) indicating switch failure. - Unstable Engine Idle: Especially if the engine idle is unstable after a cold start, possibly due to improper operation of the cold start injector.

Preparation: - Disconnect the vehicle battery's negative terminal to ensure safety. - Gather necessary tools such as wrenches and screwdrivers. 2. Locate the Cold Start Injector Time Temperature Switch: - Open the engine hood and locate the cold start injector time temperature switch, typically found near the engine intake manifold. 3. Remove the Old Temperature Switch: - Disconnect the electrical connector from the temperature switch. - Use an appropriate wrench to remove the temperature switch from the engine. 4. Install the New Temperature Switch: - Install the new cold start injector time temperature switch in the appropriate position on the engine. - Tighten the switch securely to ensure a good seal. - Reconnect the electrical connector. 5. Reconnect the Battery and Test: - Reconnect the vehicle battery's negative terminal. - Start the engine and check for any leaks or issues. - Ensure the engine runs smoothly during cold starts. 6. Clear Diagnostic Codes: - If there were any related fault codes, use a diagnostic tool to clear them. By following these steps, you can replace the cold start injector time temperature switch themselves, restoring the cold start performance of their vehicles.
