What P3410 means
P3410 covers a cylinder 2 deactivation system that is electrically intact but does not do what is commanded, such as valves that keep opening or fail to return. No manufacturer documents this code publicly. GM checks this behavior on the L84 under its own code P3499, by watching manifold pressure while cylinder 2 should be off; Ford uses the matching cylinder 1 code P3402. GM bulletin 21-NA-036 for 3.6 L V6 engines shows how such faults appear in practice: oil leaking past the control valve or rockers that do not latch cause misfires on cylinder 2 (P0302). Circuit faults belong to P3409, P3411 and P3412. Expect roughness and lost economy.
P3410 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyHard
- Typical labor0.5 to 12 hours
- Clears after repairAfter a drive cycle
Symptoms of P3410
- Misfire on cylinder 2, often after a reduced-cylinder phase
- Check engine lamp on
- Vibration at light load
Common causes of P3410
- Most likelyOil bleeding past the control valve seal, pressure lost
- PossibleRocker or lifter of cylinder 2 not latching
- PossibleLow or degraded oil
- Less likelyBroken solenoid tip left in the bore keeps a new valve from seating
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P3410 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 3 | Mixed range: generic and manufacturer-specific codes. |
| 4 | Area: auxiliary emission controls (catalytic converter, EGR, EVAP). |
| 10 | The exact fault in that area. |
What to do next
- Note P3410 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P3410
What does P3410 mean?
P3410 means "Cylinder 2 Deactivation/Intake Valve Control Performance". P3410 covers a cylinder 2 deactivation system that is electrically intact but does not do what is commanded, such as valves that keep opening or fail to return. It is a generic code, so it means the same on every make.
Is it safe to drive with P3410?
Usually yes, for a short time, if the check engine light is steady and the car drives normally. If the light flashes or the car runs badly, stop and have it checked.
Will P3410 fail an emissions test?
Yes, it can. P3410 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P3410 to fix?
Difficulty: hard. A typical repair takes 0.5 to 12 hours of work. This is a job for a workshop.
Will P3410 clear itself after the repair?
After the repair the car has to complete a drive cycle (a mix of city and highway driving) before the test runs again. Until then the readiness monitor shows "not ready", which can fail an inspection.
