P3441 code definition

For eight-cylinder engines that have the option to operate in four-cylinder mode, the PCM (powertrain control module) may detect that the values it should be getting from the MAP (manifold absolute pressure), MAF (mass air flow), and TP (throttle position) sensors are incorrect or out of range to deactivate cylinder 6. If this is the case, a P3441 code will be stored by the PCM, and the Check Engine Light will turn on.

What the P3441 code means

To increase fuel efficiency, certain V8 models can deactivate two cylinders on each engine bank to operate in V4 (four-cylinder) mode. To do this, the engine signals specific valve lifters to deactivate the selected cylinders’ ability to open and close. A P3441 code will be set when the PCM doesn’t receive the correct information from the MAF, MAP, and TP sensors and is unable to enter V4 mode.

What causes the P3441 code?

A number of factors can affect the engine’s ability to deactivate cylinder 6 on the right bank of the engine block. These include:

  • A problem with the cylinder 6 deactivation solenoid
  • Restricted engine oil passageways
  • Some issue with the engine’s mechanical condition
  • Lower than normal oil pressure
  • A shorted or open circuit to the cylinder deactivation solenoid or its harness

What are the symptoms of the P3441 code?

If the PCM detects a P3441 code or any other code related to the deactivation of one of the cylinders involved in this process, there will likely be no significant symptoms affecting the vehicle’s drivability. The Check Engine light will illuminate, and the engine may vibrate more than it normally does. You may also notice a decrease in fuel efficiency, but these are the only common symptoms associated with this code.

How does a mechanic diagnose the P3441 code?

If a P3441 code is detected, the mechanic will need to use an OBD-II scanner to read it and any other codes that the PCM has stored. If any of the cylinders before cylinder 6 are having problems with deactivation, their issues should be resolved first, as should any other related codes.

After dealing with any other codes of this kind, the mechanic will then check the oil pressure and the levels of oil in the engine. If necessary, they will then add more oil or perform an oil change. After taking these steps, they’ll clear all of the recorded codes and retest the engine to ensure that the P3441 code doesn’t get stored again. If the code appears again, they will continue with further diagnostic work to find the root cause of the problem and solve it.

Common mistakes when diagnosing the P3441 code

Some mechanics and vehicle owners will assume that the problem is in the deactivation solenoid for cylinder 6 and will not take steps to check that the engine’s oil passageways are clear. Failing to clean out a restricted oil passageway is a good way to do a lot of expensive work that will not actually solve the problem.

How serious is the P3441 code?

It’s very important that you get a proper diagnosis and the right repairs done as soon as possible with a P3441 code. While it will likely not do immediate damage to the engine, the problem can significantly decrease your vehicle’s fuel efficiency, and if left alone for long enough, can do permanent damage to the engine.

What repairs can fix the P3441 code?

The right repair(s) for the job will depend on what’s causing the P3441 code to be stored. Some of the most common repairs you’ll find for this code include:

Additional comments for consideration regarding the P3441 code

Failing to address the root cause of a P3441 code could potentially do physical harm to your engine block. Also, if your vehicle is in need of an OBD-II emissions test to qualify for registration, you’ll need to get this problem addressed so that the Check Engine light will be turned off during testing.
