P3492 - OBD Trouble Code

<<See All OBD Codes

The trouble code P3492 can be described as Cylinder 12 Deactivation/Intake Valve Control Circuit High. The error code P3492 would start triggering when the PCM would detect some fault in cylinder 12 intake valve control circuit. One thing which you must keep in mind that its symptoms as well as causes would surely vary as it depends upon a number of things.

There are a number of fuel and emissions standards, so in an effort to meet that lot of manufacturers are using the cylinder deactivation systems. This system would allow the engine control module (PCM) to disable select cylinders when additional power is not required from the engine, such as at idle or when cruising on the highway. Now if the engine control module (PCM) would decide that the intake valve for cylinder number nine is not turning on or off the way is being commanded, then the powertrain control module would set up this fault code. The P3492 trouble code would indicate that a cylinder 12 intake valve control circuit which is not as per the predetermined limit has been detected by the ECM. Now when this would occur, the fault code would be stored and there would be an illumination of the malfunction indicator light.

What causes this problem with the Cylinder 12 Deactivation/Intake Valve Control Circuit High?

• Malfunctioning variable valve timing solenoid
• There might be low oil pressure
• Constricted oil passage
• Engine mechanical condition might be flawed
• Defaults in the wiring
• There might be damaged or loose connector
• Quirks in the engine control module

1. Engine Control Module - Is your car engine light still staying ON after resetting or your car engine is turning off for no reason? Then these are some common symptoms indicating that your car engine control module is defective.
2. Powertrain Control Module - The PCM works as the central computer system in an automobile’s mechanism. This auto part is in charge of all the constituents as well as the functions performed by them. Having such enormous importance in the operation of all the parts means that any defect in it will affect almost every aspect of a car.
3. Exhaust System Parts - Malfunctioning exhaust system parts may lead to a noisy engine exhaust. A significant decrease in the fuel efficiency, power and acceleration are likely to be observed first as soon as there is a fault in the exhaust system parts. So it is important to change them. Log on to Parts Avatar now for supreme quality auto parts.
4. Engine Wiring Harness - Your car ECM would not operate properly if there are some cracks or break in the engine wiring harness. Corrosion as well as physical damage are the most common reasons why you should replace an engine wiring harness. Purchase high grade engine wiring harness online from Parts Avatar Canada.
5. Electronic Control Unit - The ECU is a major component of your car's onboard computer. It's used to regulate many systems and subsystems in your car's engine, drive train and other major components. Visit us to buy best quality ECU online.
6. Diagnostic Tools - Take help of a professional mechanic to diagnose OBD code error. Use high grade diagnostic tools to resolve this issue. Buy new tools and equipment form us!

Our main motive is to achieve customer satisfaction and that’s why we will help you to diagnose P3492 code by mentioning some major symptoms below:

Common Symptoms

• Illumination in the service engine soon light
• Engine misfire associated issues
• Rising fuel consumption
• Declining engine performance
• Flashing up of the service engine soon light

If you wish to correct this fault code, then you have to follow certain steps. Correcting a problem needs your careful attention. Here are some ways with the help of which you will be able to correct the OBD Code P3492:

• It is essential to clean the blocked oil passages
• Repair or replace the quirky ECM
• Carefully clean the corrosion from connectors
• The oil and filter should be changed
• It is necessary to perform proper service of the unsound wiring
• Adjust the flawed variable valve timing solenoid

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 ecm, pcm, oil filter, mass airflow sensor, map sensor, maf sensor, throttle position sensor, powertrain control module, engine control module, intake valve, vvt solenoid, manifold absolute pressure sensor, variable valve timing solenoid, tps sensor, body control module 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:

• Use an OBD-II scanner in order to verify that the code is present, and check for other codes for any other type of error or problem that might need attention.
• The current data along with freeze frame data are recorded, and the codes are then cleared to see if they reoccur.
• The vehicle is inspected for any problems with the wiring and connectors to check for loose connections, corrosion, or shorts.
• The tests related to the cylinder 12 intake valve control circuit and components may help pinpoint the problem, as well as inspection of the current sensor and cut off switch will further helping the cause.
• The P3492 error is triggered if there is a physical problem with the cylinder 12 intake valve control circuit which could cause the engine performance to go off.

Common Mistakes When Diagnosing The P3492 Code

• There can be a failure in the powertrain control module
• Defaults in the PCM
• Some issues related to the wiring
• Variable valve timing solenoid failure
