Code P2430 Toyota Description

The P2430 diagnostic trouble code (DTC) for Toyota vehicles indicates a problem with the Secondary Air Injection System Air Flow/Pressure Sensor Circuit in Bank 1. The Secondary Air Injection System is designed to reduce harmful emissions by introducing fresh air into the exhaust system to help burn unburned fuel before it reaches the atmosphere. The air flow/pressure sensor in this system is responsible for monitoring the flow of air and pressure levels to ensure proper operation.

Cost to Fix P2430 Toyota

The typical repair costs for addressing the P2430 code on a Toyota vehicle can range from $200 to $500, depending on the specific cause of the issue and the cost of parts and labor. It's important to note that diagnostic time and labor rates at auto repair shops can vary, so it's advisable to check with local shops for more accurate pricing. Additional costs may apply if other components in the Secondary Air Injection System need to be replaced.

When is the Code Detected?

The Engine Control Module (ECM) monitors the pressure in the secondary air passage using the pressure sensor located on the air switching valve in the secondary air injection system.
If there is a defect in the sensor or the sensor circuit, the voltage level deviates from the normal operating range, the ECM interprets this deviation as a malfunction in the pressure sensor or circuit and sets a Detected Trouble Code (DTC).
