This summary uses the existing diagnostic information shown in full below.
Your car has a system that checks for gas leaks, and there's a part that warms up to help it work. This code means there's a problem with the part that heats up.
The code P240A indicates an issue with the circuit responsible for controlling the heater of the EVAP system's leak detection pump.
The EVAP (Evaporative Emission Control) system prevents fuel vapors from escaping into the atmosphere. The leak detection pump is part of this system and helps check for leaks. It has a heater to ensure it works properly in cold conditions. P240A is triggered when the control circuit for this heater is open or not functioning correctly.
• Check Engine Light is on
• Failed emissions test
• Possible fuel odor
• No noticeable symptoms in vehicle performance
• Faulty leak detection pump heater
• Blown fuse in the heater circuit
• Wiring issues such as open or short circuits
• Faulty relay controlling the heater
• Defective ECM (Engine Control Module)
EVAP: Evaporative Emission Control System
ECM: Engine Control Module
• Use an OBD-II scanner to confirm the code.
• Inspect the wiring and connectors for the leak detection pump heater.
• Check the fuse and relay associated with the heater circuit.
• Test the leak detection pump heater for continuity.
• Replace or repair damaged wiring or connectors.
• Replace the faulty leak detection pump heater.
• Replace the blown fuse or faulty relay.
• Reprogram or replace the ECM if necessary.
• OBD-II scanner
• Multimeter
• Basic hand tools (screwdrivers, pliers)

Moderate
• Toyota Camry
• Ford F-150
• Honda Accord
• Regularly inspect and maintain EVAP system components.
• Ensure proper electrical connections and wiring integrity.
• Perform periodic emissions system checks.
Sensor Issue
• Have the vehicle inspected by a professional mechanic.
• Avoid driving in extreme conditions until the issue is resolved.
Check with your vehicle manufacturer for emissions-related warranty coverage.
P240A is a relatively common code in vehicles with advanced EVAP systems, often due to wiring issues or component failures.
Moderate – It should be addressed to prevent emissions issues, but it may not immediately affect drivability.
Ignoring emissions-related codes can lead to failed emissions tests and potential fines.
• Vehicle at operating temperature
• Stable electrical system voltage
The leak detection pump and its heater are typically located near the fuel tank or in the rear of the vehicle.
Q: Can I drive with a P240A code?
A: Yes, but it's best to fix it soon to avoid emissions issues.
Q: Will a P240A code affect my car's performance?
A: Not usually, but it can cause emissions test failures.
