It can be described as the Cylinder 5 exhaust valve control circuit high

OBD error code P2440 will be set by your vehicle’s powertrain control module when it detects that some performance problems with the voltage or resistance in the cylinder 5 exhaust valve control circuit. This will result in the illumination of the check engine light which will keep on flashing until you resolve the code. To know about a few of the common causes behind this OBD error code P3440, take a look at the sections below.

What causes this problem with the Cylinder 5 Exhaust Valve Control Circuit High?

• Less than required oil level or pressure
  
• Malfunctioning cylinder deactivation solenoid
• Open or shorted cylinder deactivation harness
• Poor electrical connections
• Congested oil passage
• Mechanical condition with the engine

1. Powertrain Control Module - Also abbreviated as PCM, powertrain control module is an integral control unit. So, a defective one should be changed immediately replaced or reprogrammed to avoid any further damage.

3. Oil Filter - Problem with your vehicle’s oil filter? Don’t let that hold you back. The PartsAvatar website is the best place to find the most efficient and cost-effective oil filters for your car.
4. Engine Oil - This is a known fact that changing your contaminated engine oil might help you to solve your problem, considering it can become one of the potential causes.
5. Variable Valve Timing Solenoid - If you are the one Looking for VVT solenoid to fix this problem then all you need to do is to browse through our website. You can find the most budget friendly VVT solenoid with us.
6. Engine Control Module - Your vehicle’s PCM that is also known as the “brain” of the car should be changed immediately if broken or defective in order to avoid further problems caused due to an Error Code P3440. If you need one for your vehicle, you can easily find one with us.

It is essential to know the symptoms of an issue as only then you would be able to solve the problem. So that’s why we have listed out some major symptoms of OBD Code P3440 here:

Common Symptoms

• Steep fall in fuel efficiency
• Declining engine performance
• Misfiring engine
• Flashing check engine light
• Illumination of service soon light

Here are some ways with the help of which you will be able to correct the OBD Code P3440

• Start by repairing the deactivation solenoid, if found faulty
• Make all the connector corrosion free
• Loose, damaged or corroded wires can be problematic, so make sure to get rid of them and repair or replace them
• Repair or replace the blocked oil filter
• Block free all the oil passages
• Make sure to fix the faulty engine control module

Here are some steps which you should follow in order to diagnose this fault code:

Check the engine oil and check if it is serviced up to the needed level. Once this is done, then the next step is to look for all the related components and parts with the cylinder 5 exhaust valve control circuit. Once located, check for any physical damage through an in-depth visual inspection. Check the wiring and connectors for any bare wires, burn spots, scraped etc. After all of this contact a technical to check for the configurations and see if every incorporated component within the cylinder 5 exhaust valve control circuit is in good shape.

Advanced Steps - These steps will be vehicle specific and will need a few technical equipment to ensure safety and accuracy. You will need a digital multimeter and technical references. Here the oil pressure gauge will help you in your troubleshooting process.

Voltage Checks - Also the required voltage will depend upon the specific vehicles and the circuit configurations. In case you diagnose the lack of power source or ground, then you might require continuity tests to check the wiring integrity, connectors integrity and other components. Also perform the continuity tests with the power removed. No continuity will be an indication of faulty wiring that is open, shorted or corroded and must be repaired or replaced.

Common Mistakes When Diagnosing the P3440 Code

Beware of the following misdiagnoses

• Low engine oil level
• Faulty powertrain control module
• Faulty vvt solenoid
• Issues with the system wirings
