Code P2402 Scion Description
The P2402 code for Scion vehicles indicates an issue with the Evaporative Emission Leak Detection Pump being stuck ON. This system is a crucial component of the vehicle's emissions control system, responsible for detecting leaks in the fuel vapor system. When this pump is stuck ON, it can lead to various problems related to emissions control and overall vehicle performance.
Common Causes of P2402 Scion
- Faulty Evaporative Emission Leak Detection Pump: The most common cause of the P2402 code is a malfunction in the pump itself, such as a stuck valve or sensor.
- Wiring Issues: Damage to the wiring connected to the pump can prevent proper communication and operation.
- Vacuum Leak: A leak in the vacuum system that controls the pump can lead to its constant activation.
- Blockage in the System: Debris or a blockage in the fuel vapor system can prevent the pump from functioning correctly.
Symptoms of P2402 Scion
- 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.
- Decreased Fuel Efficiency: A malfunctioning Evaporative Emission Leak Detection Pump can lead to decreased fuel efficiency as the system struggles to maintain proper emissions control.
- Rough Idle: In some cases, the engine may experience rough idling or hesitation during acceleration due to the malfunctioning pump.
- Strong Gasoline Odor: A noticeable gasoline odor inside or outside the vehicle may indicate a leak in the fuel vapor system caused by the stuck pump.

Frequently Asked Questions about P2402 Scion Code
What does the OBDII code P2402 mean on a Scion?
P2402 indicates that the Evaporative Emission Leak Detection Pump is stuck in the "ON" position, which means the ECU has detected a malfunction in the EVAP system's leak detection process.
What are the common symptoms of code P2402 in a Scion?
Symptoms may include an illuminated check engine light, reduced fuel efficiency, a noticeable fuel smell, or failed emissions testing.
What causes the P2402 code to appear?
Common causes include a faulty leak detection pump, damaged wiring or connectors, a malfunctioning EVAP system pressure sensor, or issues with the ECU.
Can I drive my Scion with the P2402 code?
While the vehicle may still be drivable, ignoring the code can lead to increased emissions, possible fuel vapor leaks, and complications during emissions testing.
How do I diagnose the P2402 code in my Scion?
Start by inspecting the leak detection pump, EVAP system wiring, and connectors for damage. Use a scan tool to check for related codes and perform an EVAP system pressure test if necessary.
How do I fix the P2402 code on my Scion?
Repairs may involve replacing the leak detection pump, repairing or replacing damaged wiring and connectors, or addressing any ECU-related issues.
