P2402 2006 Toyota Camry Code - EVAP System Leak Detection Pump Control Circuit High
Quick Answer
The P2402 diagnostic trouble code (DTC) for a 2006 Toyota Camry indicates a problem with the EVAP (Evaporative Emission Control System) 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, Wiring Issues: Damaged or corroded wiring connections to the LDP can lead to incorrect voltage readings, EVAP System Leak: A leak in the EVAP system can cause the LDP to work harder, resulting in a 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 2006 Toyota Camry Description
The P2402 diagnostic trouble code (DTC) for a 2006 Toyota Camry indicates a problem with the EVAP (Evaporative Emission Control System) System Leak Detection Pump Control Circuit being too high. The EVAP system is responsible for capturing and storing fuel vapors to prevent them from escaping into the atmosphere. The Leak Detection Pump (LDP) is a key component of this system, as it pressurizes and tests the integrity of the system for leaks.
Common Causes of P2402 2006 Toyota Camry
- Faulty Leak Detection Pump: The LDP itself may be malfunctioning, causing the control circuit to register a high voltage.
- Wiring Issues: Damaged or corroded wiring connections to the LDP can lead to incorrect voltage readings.
- EVAP System Leak: A leak in the EVAP system can cause the LDP to work harder, resulting in a high voltage reading.
- Faulty EVAP Pressure Sensor: A malfunctioning pressure sensor can also trigger this code.
- ECM (Engine Control Module) Issue: A problem with the ECM that controls the EVAP system can cause the circuit to register high voltage.
Symptoms of P2402 2006 Toyota Camry
- Check Engine Light: The most common symptom associated with this code is the illumination of the check engine light on the dashboard.
- Reduced Fuel Efficiency: A malfunctioning EVAP system can lead to increased fuel consumption as fuel vapors escape.
- Strong Fuel Odor: If fuel vapors are leaking from the EVAP system, a strong fuel odor may be noticeable around the vehicle.
- Failed Emissions Test: If the EVAP system is not functioning properly, the vehicle may fail emissions testing due to increased emissions.
How to Fix P2402 2006 Toyota Camry
- Diagnose the Issue: Use a scan tool to retrieve the DTC and perform a visual inspection of the EVAP system components.
- Test the Leak Detection Pump: Check the functionality of the LDP by applying power and ground to it to see if it activates.
- Inspect Wiring and Connections: Check for any damaged or corroded wiring connections to the LDP and repair as needed.
- Check for EVAP System Leaks: Perform a smoke test or pressure test on the EVAP system to identify any leaks that may be causing the issue.
- Replace Faulty Components: If the LDP, wiring, or other components are found to be faulty, replace them as necessary.
Cost to Fix P2402 2006 Toyota Camry
The typical repair costs for addressing a P2402 code on a 2006 Toyota Camry can vary depending on the specific cause of the issue. In general, parts for the EVAP system, such as the Leak Detection Pump or wiring components, can range from $100 to $300. Labor costs at an auto repair shop can range from $100 to $300, depending on the shop's hourly rates and the complexity of the repair. Overall, the total cost for addressing this issue may range from $200 to $600. It is advisable to consult with a trusted mechanic or repair shop to get a more accurate estimate based on the specific circumstances of the vehicle.
