P3415 is a diagnostic trouble code (DTC) for "Cylinder 2 Exhaust Valve Control Malfunction". 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 for $114.99 . Once we are able to diagnose the problem, you will be provided with an upfront quote for the recommended fix and receive $20.0 off as a credit towards the repair. All our repairs are backed by our 12-month / 12,000-mile warranty.
P3415 is the fault code for Cyl2 Exhaust Valve Ctrl Circ Low. Cyl2 specifies that the issue is likely taking place in engine cylinder number 2.
This code indicates there is a problem with the exhaust valve on cylinder number 2. The ECM (engine control module) tells these valves when to open and close, in order to carry exhaust vapors away from the engine after the fuel has been used. When this valve fails to open at the correct time, or at all, the ECM detects that the signal being received falls outside of the expected parameters, and the vehicle will set code P3415 or another cylinder exhaust valve related code.
This code can have a number of causes, including one or more of the following:
A short or an open in the solenoid wiring harness
A loose connection
A faulty exhaust valve control solenoid
Low oil levels or clogged oil passages
Timing chain maladjustment
Camshaft actuator malfunction
Rarely, this problem may be caused by a faulty PCM or ECM, but other causes should be exhausted first.
As with any cylinder malfunction, the Check Engine light will likely illuminate. You may also experience poor acceleration, and fuel efficiency may be affected because the variable valve timing system is typically disabled when a fault of this sort occurs.
Your technician may perform the following steps in order to diagnose the source of the problem:
Use of a code scanner to verify that the code is stored, and to check for any concurrent codes
Diagnosis and repair of other codes, in the order the events occurred
Test of the exhaust valve solenoid using a scan tool and/or test solenoid
Valve lifter inspection
This code isn’t as serious as some problems, but it should be addressed as soon as possible due to the fact that fuel economy and engine performance can both be affected by an exhaust valve malfunction.
Repairing code P3415 may involve one or more of the following:
Exhaust valve solenoid replacement
Valve lifter replacement
Timing and/or camshaft actuator adjustment
Due to the fact that cylinder valve operation involves many moving parts, as well as complex circuitry, this fault is most efficiently diagnosed by a professional with the proper tools which can offer detailed information on the problem. Making sure that all possible data is collected, using the most advanced diagnostic and testing tools, ensures that expensive parts – such as sensors – aren’t replaced if they don’t need to be. Consulting a qualified technician for a cylinder exhaust valve malfunction can save you time, money, and headaches.
