Guide To P3443 OBD Error Code Solutions

<<See All OBD Codes

OBD error code P3443 is a generic powertrain diagnostic trouble code, commonly referred as DTC. It applies to all OBD-II vehicles. In Spite of the fact that it is a generic code but the repair steps may vary depending upon the specific make manufacturer. This code might lead to fall in engine efficiency and a rise in fuel consumption. If you wish to know more about this error code P3443, then you must go through our subsequent sections.

Ever wondered what this P3443 code depicts? What is your vehicle trying to convey to you? P3443 error code is a generic OBD code that indicates that your vehicle’s powertrain control module has detected cylinder 6 deactivation/intake valve control circuit refuses to turn on or off as commanded. To know more about this code and few of its common causes, take a look at the following section.

What causes this problem with the Cylinder 6 Deactivation/Intake Valve Control Circuit Low?

• Non-operative variable valve timing solenoid
• Low engine oil or pressure level
• Blocked oil passage
• Corroded, lose or damaged wiring and connectors
• Faulty engine control module

1. Powertrain Control Module - As your car’s PCM is responsible for making the engine and transmission work in synchronization. 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 P3443.
2. Engine Control Module - Error code P3443 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 P3443 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 P3443 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

Here are some steps which you should follow in order to diagnose this 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 upto the needed level. Once this is done, then the next step is to look for all the related components and parts with the cylinder 6 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 6 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 P3443 Code

Beware of the following misdiagnosis

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