P2402 2011 Toyota Camry Code - EVAP System Leak Detection Pump Control Circuit High
Quick Answer
The P2402 diagnostic trouble code (DTC) for a 2011 Toyota Camry indicates a problem with the EVAP (Evaporative Emission Control) system Leak Detection Pump Control Circuit being too high. Common causes include Faulty Leak Detection Pump: The LDP itself may be malfunctioning, causing the control circuit to register a high voltage, Damaged Wiring: Wiring that connects the LDP to the ECM may be damaged or corroded, leading to electrical issues, Blown Fuse: A blown fuse in the circuit that controls the LDP can cause the high voltage reading. Severity is High - diagnose this code as soon as possible. Driving is not recommended if the warning light is flashing, the engine runs poorly, or safety-related symptoms are present.

Code P2402 2011 Toyota Camry Description
The P2402 diagnostic trouble code (DTC) for a 2011 Toyota Camry indicates a problem with the EVAP (Evaporative Emission Control) system Leak Detection Pump Control Circuit being too high. The EVAP system is responsible for capturing and storing fuel vapors from the fuel tank to prevent them from escaping into the atmosphere. The Leak Detection Pump (LDP) is a crucial component of this system, as it pressurizes and tests the system for leaks.
Common Causes of P2402 2011 Toyota Camry
- Faulty Leak Detection Pump: The LDP itself may be malfunctioning, causing the control circuit to register a high voltage.
- Damaged Wiring: Wiring that connects the LDP to the ECM may be damaged or corroded, leading to electrical issues.
- Blown Fuse: A blown fuse in the circuit that controls the LDP can cause the high voltage reading.
- ECM Malfunction: A problem with the engine control module (ECM) can also trigger this code.
Symptoms of P2402 2011 Toyota Camry
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the vehicle's dashboard.
- Rough Idle: A malfunctioning EVAP system can cause the engine to run rough or idle inconsistently.
- Decreased Fuel Efficiency: A leak in the EVAP system can lead to fuel vapors escaping, resulting in decreased fuel efficiency.
- Failed Emissions Test: If the EVAP system is not functioning properly, the vehicle may fail an emissions test due to increased emissions.
How to Fix P2402 2011 Toyota Camry
- Diagnose the Issue: Use a scan tool to read the DTC and pinpoint the exact cause of the high voltage reading.
- Inspect Wiring: Check the wiring harness for any damage or corrosion, and repair or replace as needed.
- Test the Leak Detection Pump: Test the LDP to determine if it is functioning properly. Replace if necessary.
- Check Fuses: Inspect the fuses related to the EVAP system and replace any blown fuses.
- Clear Codes: After completing the repairs, clear the DTC and test drive the vehicle to ensure the issue has been resolved.
Cost to Fix P2402 2011 Toyota Camry
The cost of repairing a P2402 DTC on a 2011 Toyota Camry can vary depending on the specific cause of the issue. In general, the cost of parts for this repair can range from $100 to $300, with labor costs adding an additional $100 to $200.
