Error Code P3433: What It Means & What To Do?

<<See All OBD Codes

OBD Error Code P3433 is a generic trouble code and mostly applies to all the OBD-II vehicles. It might be more prominent in Volkswagen, Audi, Nissan, Mazda, Ford vehicles though not limited only to them. Though this code is generic but the steps to fix and diagnose it may vary from vehicle to vehicle depending upon the manufacturer configurations. To know more about this error code, take a look at the section below.

Flashing of the check engine light and fall in overall engine performance will be accompanied with the symptoms of the error code P3433. Your vehicle’s engine control module will set this error code when it detects the inappropriate voltage or resistance within the cylinder 5 deactivation/intake valve control circuit. What causes this problem? To know that have a look at the section below.

What causes this problem with the Cylinder 5 Deactivation/Intake Valve Control Circuit/Open?

• Malfunctioning cylinder deactivation solenoid
• Low level of engine oil
• Low oil pressure
• Blocked or restricted oil passages
• Corroded or loose wires and connectors
• Malfunctioning engine control module

1. Powertrain Control Module - As your car’s PCM is responsible for making the engine and transmission work in synchronisation. Any issue with the powertrain control module will cause major problems with the efficient running of the vehicle. So, don’t think twice and replace the faulty PCM now to get rid of this error code P3433.
2. Engine Control Module - Error code P3433 flashing? It might be due to a faulty ECM. Engine control module if faulty can cause misinterpretation of correct data thus leading to wrong operational decisions which will affect the transmission and overall engine performance. Thus, replace faulty module and reprogram it now!
3. Engine Oil - Fuel Cap is perfectly fitted but you still find the trouble code P3433 flashing? In such a situation your engine oil might not be the appropriate one according to your vehicle’s specifications. Why don’t you think of checking our website for our wide range of engine oils?
4. Variable Valve Timing Solenoid - if you are facing OBD error code P3433 then it might demand a new variable valve timing solenoid if found faulty. If you wish to get it done at the earliest then you can simply browse through our website to find one for your make and model.
5. Intake Valve - Since intake valves are responsible for controlling the amount of working fluid entering the cylinder of an engine, so it makes it extremely important to make sure that you have the right one installed in your vehicle.
6. Oil Filter - Do not let the harmful particles and contaminants enter your vehicle’s engine, make sure your car’s oil filter are in good shape and our doing their job best. If not, then don’t think twice and replace the faulty ones right now.

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 P3433 here:

Common Symptoms

• Flashing of check engine light
• Illumination of service soon light
• Falling fuel economy
• Falling and declining engine performance
• Engine misfires

Here are some ways with the help of which you will be able to correct the OBD Code P3433

• Begin correcting this error code by replacing or repairing the deactivation solenoid
• The next step is to clean off all the corrosion from the connectors
• Repair or replace the faulty oil filters
• Make sure that the engine oil is of right specifications and filled upto right level
• Make sure to clean the blocked oil passages
• Repair the faulty car’s ecm

Here are some steps which you should follow in order to diagnose this P3433 fault code: 

Start by researching the technical service bulletins specific to your vehicle make and model. Next step is to the engine oil and check if it is serviced up to the needed level. Once this is done, then 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 wirings 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 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 P3433 Code 

Beware of the following misdiagnosis

• Low engine oil level
• Faulty powertrain control module
• Faulty vvt solenoid
