P2409 - OBD Trouble Code

Variations in evaporative emission control system pressure or flow are received by the PCM in degrees of voltage. If the PCM detects a voltage reading that does not coincide with the manufacturer’s reference voltage, a code will be stored and a malfunction indicator will be illuminated. Some models require multiple failure cycles for service engine soon lamp illumination but a code is normally stored on the first failure. Stored codes presented without malfunction indicator lamp illumination may be read as pending codes.

What causes this problem with the Fuel Cap Sensor/Switch Circuit Range/Performance?

• Loose/cracked fuel cap
• Faulty fuel tank pressure sensor
• Damaged or corroded wiring and connectors
• Damaged gasket on the gas cap
• Charcoal canister damaged
• Purge control solenoid problematic
• Vacuum hoses damaged
• Fuel vapour hoses damaged
• Faulty flow sensor
• Faulty Powertrain Control Module

1. Engine Control Module - Want to know the most common reason behind the failure in the engine control module? Corrosion or damage because of moisture can cause ECM failure. Corrosion might enter the ECM through the wiring harness and moisture can enter by a failure in the seals in the ECM itself.
2. Powertrain Control Module - The PCM makes the engine and transmission work in tandem. Any issue with the powertrain control module will cause major problems with the efficient running of the vehicle.
3. Electronic Control Unit - If your vehicle fails to start for no apparent reason, this is also a good indicator that there can be some issues with the ECU. If you check the car battery, starter and other common electrical components, and the vehicle still does not start, a quirky electronic control unit should be the next logical thing to consider.
4. Diagnostic Tool - In order to fix these errors, you need few diagnostic tools to get your car problems pointed out easily. Our diagnostic tools collection will come handy to do so and resolve all your vehicle problems. Visit today!
5. Fuel Cap - One of the most common symptoms of an issue with the gas cap is a cap that does not tighten properly. Most gas caps are designed to click once they are tightened sufficiently. If the cap does not click, or clicks and then pops loose again then that may be a sign that it may need to be replaced.
6. Fuel Tank Pressure Sensor - This sensor is linked to the vehicle’s computer system, and in the event that there’s a leak in the EVAP, or perhaps a problem with the sensor, you will see a “check engine” signal. Apart from that, the sensor sends info to the powertrain control module (PCM), the part that controls how the engine works and manages fuel usage. The pressure sensor is vital for the smooth functioning of the engine through the PCM, and for the detection of leaks.
   

Have you ever wondered why is it so important to know the symptoms of the problem? Well, it is extremely essential to know the symptoms of the problem in order to detect it. Keeping this in mind, let’s throw some light on few common symptoms of OBD error code P2409.

Common Symptoms

• Check Engine Light on
• Decreased fuel economy
• Increased emissions
• Affected fuel delivery

To correct this issue you might need to undergo few replacements for the defective parts such as:

• Fuel cap replacement
• Purge control solenoid replacement
• Charcoal canister replacement
• Fuel vapour hoses replacement
• Vacuum checks and replacement
