P3468 - OBD Trouble Code

<<See All OBD Codes

See the error code P3468 flashing? Don’t worry, Parts Avatar to the rescue! Here we have mentioned all that you need to know about the error code P3468. This OBD-II error code P3468 signifies a malfunction within the intake valve on cylinder number 9. Whenever, the powertrain control module identifies that the calculated values of the mass airflow sensor, the throttle position sensor, and the intake control manifold absolute pressure sensor are failing to fall within the acceptable range for V4 mode, the P3468 code is stored.

This OBD-II code decreased engine performance is also referred to as a cylinder 9 deactivation/intake valve control circuit high. For achieving the fuel and emission standards, a number of manufacturers utilize cylinder deactivation systems. Further, this system aids enabling the engine control module (ECM) to deactivate select cylinders when the additional power isn’t required from the engine (such as idle or at cruising). When the intake valve for cylinder number nine is not turning on or off as per the commandments, the error code P3468 will be set by the powertrain control module.

What causes this problem with the Cylinder 9 Deactivation/Intake Valve Control Circuit High?

• Jammed cylinder deactivation solenoid
• Fall in the engine oil level or pressure
• Blockage in the oil passage
• Fault in the wiring
• Loose or corroded connector
• Distorted ECM

1. Powertrain Control Module - An unsound PCM? Well, do you have any idea about the extent to which it can damage your system? A faulty powertrain control module brings along issues like a malfunction in the functioning of the entire engine, also the sparks and ignition timing from the spark plugs are controlled and received by the PCM. So, to avoid a whole lot of repairs, we simply advise you to change your PCM now. Log into Part Avatar for best quality PCMs at the best prices.
2. Exhaust Valve - A jammed exhaust valve tuning valve can end up being the chief host inviting the error code P3468. So, replacing one can be one of the wisest decisions to avoid a problematic system.
3. Mass Airflow Sensor - A failed or broken mass air flow sensor can often invite problems like erratic engine behaviour or result in an inefficient engine. Now get your new mass air flow sensor right at your doorstep with Parts Avatar. Tune in now.
4. Manifold Absolute Pressure Sensor - This essential unit, if faulty should be changed right away as it brings along a lot of problems including difficulties in starting the vehicle, erratic idle and a misfiring condition too. Now get your new absolute pressure sensor delivered easily with Parts Avatar. Tune in now!
5. Intake Valve - Damaged intake valve can end up being very problematic. In addition to the error code, it also invites problems a poor engine performance, weak acceleration and engine stalls. So, replacing one can be one of the wisest decisions to avoid a problematic system.
6. Engine Oil - Facing the error code P3468? An inferior quality engine oil can always be hazardous for the system also it is one of the primal causes behind the occurring of the error code P3468. It triggers problems like an inability to shift up and a decreased fuel economy. Tune into Parts Avatar for supreme quality engine oil at economical prices.
7. Engine Control Module - No start condition, an engine stalling and engine performance issues are likely to follow a bad engine control module. Log into Parts Avatar now to get your error code P3468 fixed.

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P3468 code by mentioning some major symptoms below:

Common Symptoms

• The driver is likely to notice engine misfiring
• Rise in the fuel consumption
• Weak engine performance
• An illuminated service engine soon light or check engine light

Have a look at some ways with which you can correct the P3468 code:

• Repair or replace a defective cylinder deactivation solenoid
• Repairs or replacements should be performed to fix a damaged cylinder deactivation solenoid (test it the same way as you tested the solenoid 1)
• Cleansing of the debris and dirt accumulated on the engine should be performed. This may require you to dismount the engine for thorough cleansing
• Make sure all of it performed after proper research

There is no need to get strained if your OBD code is still flashing up as we are here at your service. Have a look at our superior variety of PCM, exhaust valve, mass airflow sensor, throttle position sensor, intake control manifold, absolute pressure sensor, cylinder deactivation solenoid, valve lifter, intake valve, exhaust valve, cylinder deactivation solenoid, engine oil, ECM and many more. Now all your problems would vanish within no time.

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

To begin with, firstly ensure that the engine oil levels and pressure levels are up to the mark. Then make use of the OBD-II scanner to gather any diagnostic trouble codes that have already been stored by the powertrain control module (PCM). It is important to note that in case the PCM has stored other codes linked to deactivation or oil pressure, they should be addressed first. We advise you to work in the order that the codes appear on the PCM. Then the OBD-II scanner should be employed to clear the trouble codes. Perform a retest of the cylinder deactivation solenoid 1 by activating it with a scan tool. If a solenoid is working well, it is likely to vibrate and produce a ‘cling’ sound. Check the oil passages for dirt and rubbish, if in case, the cylinder deactivation solenoid 1 is not working as per the requirements. Also, clean the vehicle’s oil passages too. A repair or replacement of the solenoid will be required, although, if the cylinder deactivation solenoid 1 is working well, then the cylinder deactivation solenoid 7 should be inspected. It is essential to test it as other solenoids, that is by activating it by a scan too. Check the oil passages to the lifter if all solenoids are working in order. The passages should be cleaned if required. In extreme circumstances, the engine block should be dismounted and cleaned completely. Ensure that you are trained enough to perform this procedure, as it can become quite challenging and difficult to reassemble the system without having proper experience and knowledge.

Common Mistakes When Diagnosing the P3468 Code

Here we have listed a few common mistakes that should be avoided:

• Low engine oil levels
• Failed powertrain control module (PCM)
• Faulty variable valve timing solenoid
• Damaged wiring
