P2402 2008 Toyota Camry Code - EVAP System Leak Detection Pump Control Circuit High
Quick Answer
The P2402 diagnostic trouble code (DTC) for a 2008 Toyota Camry specifically relates to the EVAP (Evaporative Emission Control) system. Common causes include Faulty Leak Detection Pump: The LDP itself may be malfunctioning, causing the high voltage signal detected by the control circuit, Wiring Issues: Damage or corrosion to the wiring connecting the LDP to the vehicle's computer can also trigger this code, EVAP System Leak: A leak in the EVAP system can cause the LDP to work harder, leading to a high voltage signal. 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 2008 Toyota Camry Description
The P2402 diagnostic trouble code (DTC) for a 2008 Toyota Camry specifically relates to the EVAP (Evaporative Emission Control) system. More specifically, it indicates a problem with the 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 crucial component of this system as it monitors for leaks in the system.
Common Causes of P2402 2008 Toyota Camry
- Faulty Leak Detection Pump: The LDP itself may be malfunctioning, causing the high voltage signal detected by the control circuit.
- Wiring Issues: Damage or corrosion to the wiring connecting the LDP to the vehicle's computer can also trigger this code.
- EVAP System Leak: A leak in the EVAP system can cause the LDP to work harder, leading to a high voltage signal.
- Faulty EVAP System Components: Other components of the EVAP system, such as the purge valve or charcoal canister, may be malfunctioning and affecting the LDP's operation.
Symptoms of P2402 2008 Toyota Camry
- Check Engine Light: The most common symptom associated with the P2402 code is the illumination of the check engine light on the vehicle's dashboard.
- Reduced Fuel Efficiency: A malfunctioning EVAP system can lead to increased fuel consumption as fuel vapors are not being properly contained.
- Rough Idle: In some cases, a faulty EVAP system can cause the engine to idle roughly or even stall.
- Strong Fuel Odor: If there is a leak in the EVAP system, you may notice a strong smell of fuel around the vehicle.
How to Fix P2402 2008 Toyota Camry
- Diagnose the Issue: Use a scan tool to read the DTC and pinpoint the exact cause of the problem.
- Inspect Wiring: Check the wiring harness for any damage, corrosion, or loose connections. Repair or replace as necessary.
- Test the Leak Detection Pump: Test the LDP to determine if it is functioning correctly. Replace if faulty.
- Check for EVAP System Leaks: Perform a smoke test or pressure test to identify any leaks in the EVAP system. Repair leaks as needed.
- Clear Codes: Once the issue has been resolved, clear the DTC and test drive the vehicle to ensure the problem has been fixed.
Cost to Fix P2402 2008 Toyota Camry
The cost of repairing a P2402 code on a 2008 Toyota Camry can vary depending on the specific cause of the issue. In general, you can expect to pay anywhere from $150 to $500 for parts and labor.
