What does code P3400 mean?

Error Code P3400 is defined as Cylinder Deactivation System Bank 1, indicating performance issues with the said component.

What causes code P3400?

A stored code P3400 means that the powertrain control module (PCM) has detected an abnormality in the cylinder deactivation system for engine bank one. Under certain driving conditions, all of the engine’s horsepower is not needed. These driving conditions typically involve low throttle and highway speeds.

Can low oil cause P3400?

Now for the answer to the most important question: “How do I fix trouble code P3400?” The most common cause of this problem is low oil level or pressure. Start by checking your oil levels and put more oil in if necessary. Afterward, you can try driving the vehicle and see if the code reappears.

Why is cylinder deactivation bad?

Although most V8 engines are inherently well-balanced, the amplitudes of torsional vibrations that occur within a V8 engine are for the most part determined by both engine speed and load, so when the same cylinders are always deactivated regardless of the engine speed and load, the loss of power contributions by …

What is diagnostic code P0300?

P0300 indicates that two or more cylinders are experiencing misfires. A misfire occurs when an insufficient amount of fuel is burned in a cylinder. A misfire from two or more cylinders can be caused by many reasons from a faulty ignition system, fuel system, or internal engine failure.

What does Valve pause system Stuck Off Bank 1 mean?

|P3400 HONDA Meaning If there is a difference between the oil pressure conditions in the hydraulic circuit that are determined by the PCM command and the oil pressure conditions that are determined by the status of the front or rear rocker arm oil pressure switches, the system is considered faulty, and a DTC is stored.

What is VCM Muzzler?

Variable Cylinder Management (VCM) is a technology introduced by Honda on its V6 engines to improve EPA fuel efficiency numbers. It involves using the PCM to shut down cylinders at cruising conditions. You plug it inline with the engine coolant temperature sensor and adjust it based on your driving style and location.

Can cylinder deactivation be turned off?

Turning off cylinder deactivation is possible in most Active fuel management-enabled cars. Another simple way that doesn’t require you to do engine dissembling is installing the AFM disabler in the OBD-II port to prevent the computer from switching over to the four-cylinder model.

Is cylinder deactivation bad for the engine?

Most Importantly, suddenly deactivating a cylinder will shut off it’s injector immediately. This causes formation of pressure pulses inside the common rail, which is harmful. Matching of Turbocharger with engine and exhaust gas pulses in the exhaust manifold is also a concern.

What to do if you have trouble code P3400?

Now for the answer to the most important question: “How do I fix trouble code P3400?” The most common cause of this problem is low oil level or pressure. Start by checking your oil levels and put more oil in if necessary. If that does not solve the issue, then you should have a manual oil pressure test done.

What does P3400 stand for in Powertrain Control Module?

That may include but is not limited to vehicles from Honda, Dodge, Ram, GMC, Chevrolet, Chrysler, Pontiac, etc. A stored code P3400 means that the powertrain control module (PCM) has detected an abnormality in the cylinder deactivation system for engine bank one. Bank 1 denotes the bank of the engine which contains the number one cylinder.

When to use the P3400 cylinder deactivation code?

If a situation arises in which the PCM cannot make the cylinder deactivation system operational (for engine bank one), or if the PCM detects that the cylinder deactivation system has become inadvertently operational, a code P3400 will be stored and a malfunction indicator lamp (MIL) may be illuminated. Cylinder Deactivation Engine:

What does P3400 stand for on Honda Odyssey?

P3400 relates to bank 1, which is the rear cylinder head VCM solenoid. As a test, I unplugged the oil pressure sensor, and the Odyssey now ran in 6 cylinder mode ALL the time.

What’s the trouble code on a Honda P3400?

Check engine light came on, code was a P3400. Diagnosed as a rear oil pressure sensor and how to replace. It’s a 10 minute fix and not scary at all! Also applies to any other 2008, 2009, 2010, 2011 or 2012 Honda with the active displacement or their, VCM (Variable Cylinder Management). Loading…

What causes the P3400 code to set on an odyssey?

Low oil level can cause this P3400 code to set. A loose gas cap and/or dirty cabin air filter WILL NOT cause this P3400 code to set. The most obvious symptom was that the Odyssey was operating in 3 cylinder mode nearly ALL the time. There was a significant drop in power. Heres why…….
