P2402 2010 Toyota Camry Code - EVAP System Leak Detection Pump Control Circuit High
Quick Answer
5 hours after the ignition switch is turned OFF, the electric vacuum pump creates negative pressure (vacuum) in the EVAP (Evaporative Emission) system. Common causes include Faulty Vacuum Pump Module, Vacuum Pump Module harness is open or shorted, Vacuum Pump Module circuit poor electrical connection. 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.

Frequently Asked Questions about P2402 2010 Toyota Camry Code
1. What does the OBDII code P2402 mean for a 2010 Toyota Camry?
P2402 indicates an issue with the EVAP (Evaporative Emission Control System) leak detection pump control circuit, specifically that the circuit is reading a high voltage.
2. What are the common symptoms of code P2402 in a 2010 Toyota Camry?
Symptoms may include an illuminated check engine light, failed emissions tests, a noticeable fuel odor, and sometimes reduced fuel efficiency.
3. What causes the P2402 code to appear in a 2010 Toyota Camry?
Common causes include a faulty EVAP leak detection pump, damaged wiring or connectors in the pump circuit, a malfunctioning PCM (Powertrain Control Module), or a short circuit in the system.
4. How does the EVAP system work in relation to the P2402 code?
The EVAP system prevents fuel vapors from escaping into the atmosphere. The leak detection pump tests the system for leaks, and P2402 indicates a problem with the pump's control circuit.
5. Can I drive my 2010 Toyota Camry with a P2402 code?
Driving with this code is usually safe for the short term, but it may lead to higher emissions and could prevent you from passing an emissions test.
6. How do you diagnose the P2402 code on a 2010 Toyota Camry?
Diagnosis typically involves scanning for codes, inspecting the EVAP leak detection pump and its wiring, checking voltage and resistance, and testing the PCM if no faults are found.
7. How can I fix the P2402 code on my 2010 Toyota Camry?
Repairs may include replacing the EVAP leak detection pump, repairing damaged wires or connectors, or reprogramming or replacing the PCM if necessary.
8. What tools are needed to troubleshoot the P2402 code?
You’ll need an OBDII scanner, a multimeter for electrical testing, and potentially a smoke machine to test the EVAP system for leaks.
9. How much does it cost to fix the P2402 code on a 2010 Toyota Camry?
Repair costs can range from $100 to $500, depending on whether the issue is a simple wiring repair or requires replacing the leak detection pump.
10. Can a loose gas cap cause the P2402 code on a 2010 Toyota Camry?
No, a loose gas cap typically triggers a P0455 or P0442 code, not P2402, which is specific to the leak detection pump control circuit.
