Our certified mechanics come to you · 12-month, 12,000-mile warranty
P3483 is a diagnostic trouble code (DTC) for "Cylinder 11 Deactivation/Intake Valve Control Circuit Low". This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation. Our certified mobile mechanics can come to your home or office to perform the Check Engine Light diagnostic. Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.00 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
This code is defined as a deactivation/intake control valve control circuit is low on the 11th cylinder.
The P2482 code means that the intake control solenoid for the #11 cylinder is open, shorted or is pushing back with a lot of resistance. This code is logged by the vehicle’s ECM (engine control module) which is in charge of monitoring, amongst other things, the MAP sensor, MAF sensor and TP sensor. A code P2482 is a sign that the ECM is getting a reading from one of these that isn’t in line with the acceptable range for cylinder deactivation mode.
There are two main causes that could trigger a P2482 code:
One or more of the four solenoids is short, has an open circuit or is pushing back with high resistance. The vehicle’s ECM controls these solenoids, which is how it’s able to manage the vehicle’s overall performance.
Cylinder #11 has one of these problems and the engine has been given the command to switch to a different cylinder mode of operation.
It’s also worth mentioning that there’s always the chance that the ECM could simply be reporting this code in error, but this is very rare.
If the P2482 code is logged, the Check Engine Light should come on at the same time. The engine should go back to its normal cylinder operation and refuse commands to change until repairs have been made and the code cleared. Due to the solenoid failure and the injector being turned off, the engine will most likely misfire. If it does start up, the vehicle will probably lack in performance and power.
A qualified technician will carry out a diagnosis by doing the following:
Use an ODB-II scanner to download all the codes stored in the vehicle’s ECM and then review them on freeze frame.
They will then inspect the solenoid wiring connections to look for any problems that involve corroded or loose connections.
Next, the mechanic should check the #11 deactivation solenoid for the desired amount of resistance.
Finally, they will go through the manufacturer pinpoint tests for further diagnosing and replacing of the solenoid if necessary.
One mistake a mechanic must be careful to avoid is not using the OBD-II scanner to get all the freeze frame data they need for a comprehensive diagnosis. If the mechanic simply hears what the owner has to say about their vehicle and immediately begins looking for the problem, even if they finally realize cylinder #11 is in trouble, they could miss a number of other issues. Along the same lines, if they don’t clear the codes after repairs, the owner could end up returning in a week because their Check Engine light is still on.
While this code isn’t something that will end in an accident, it will absolutely make driving the vehicle extremely difficult so it should get looked at right away.
There are two main repairs a mechanic may have to implement to clear this code:
Simply replacing the solenoid for the #11 cylinder
Repairing or replacing any connector pins that have become loose or been damaged by corrosion
In rare scenarios, the mechanic may need to replace the ECM.
When addressing this code, it’s important to follow the pinpoint test when diagnosing and repairing the first code received in the ECM. Only after that one has been cleared should a mechanic continue with the next one in line. If they try jumping to the P2482 code right away (assuming it wasn’t the first in line), other issues will almost certainly be missed.
