What P3441 means
Cylinder 6 belongs to both classic V8 deactivation groups, so P3441 is a code that real engines set. On GM V8s with Active Fuel Management, which park cylinders 1, 7, 6 and 4, the 2019 tables list it for the L86 truck engine and the LT4 Corvette: with the low-side driver off, more than 200 kohm between output and ground counts as an open, and 20 failures in 25 samples (every 250 ms, from 400 rpm) store a Type B code. The L84 with Dynamic Fuel Management runs the same check from 425 rpm. Chrysler names P3441 for the 5.7 L Hemi with MDS; a STAR case blames a heat shield rubbing through the solenoid harness. Shorts on this circuit are P3443 and P3444.
P3441 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modeNot expected
- Repair difficultyMedium, DIY possible
- Typical labor0.5 to 4 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P3441
- Check engine lamp on
- Engine no longer drops to four-cylinder mode
- Possibly circuit codes for cylinders 1, 4 and 7 as well if the shared harness is damaged
Common causes of P3441
- Most likelySolenoid harness broken or chafed through (on the 5.7 L Hemi by the manifold heat shield)
- PossibleOpen coil in the cylinder 6 deactivation solenoid
- PossibleLoose or corroded connector at the cylinder 6 solenoid
- Less likelyControl module software that needs an update (Chrysler TSB 18-002-25)
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P3441 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). |
| 41 | The exact fault in that area. |
What to do next
- Note P3441 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 P3441
What does P3441 mean?
P3441 means "Cylinder 6 Deactivation/Intake Valve Control Circuit/Open". Cylinder 6 belongs to both classic V8 deactivation groups, so P3441 is a code that real engines set. It is a generic code, so it means the same on every make.
Is it safe to drive with P3441?
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 P3441 fail an emissions test?
Yes, it can. P3441 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 P3441 to fix?
Difficulty: medium. A typical repair takes 0.5 to 4 hours of work. A careful DIY repair is possible with basic tools and a scanner.
Will P3441 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
