P3415 OBD-II Trouble Code: Cylinder 2 Exhaust Valve Control Malfunction

Check Engine Light

P3415 code definition

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.

What the P3415 code means

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.

What causes the P3415 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.

What are the symptoms of the P3415 code?

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.

How does a mechanic diagnose the P3415 code?

Your technician may perform the following steps in order to diagnose the source of the problem:

How serious is the P3415 code?

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.

What repairs can fix the P3415 code?

Repairing code P3415 may involve one or more of the following:

Additional comments for consideration regarding the P3415 code

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.
