OBD-II Code
P3410
Severity
Not yet reviewed
Nobody on our side has assessed this code yet, so we are not going to guess at how serious it is.
Can you drive it
We cannot say
Treat it as unknown until a shop reads it with live data. If the check-engine light is FLASHING, stop driving as soon as it is safe to — that means an active misfire, whatever the code.
Indicative cost (USD)
$40–$4,500
From this code's diagnostic notes. Varies by vehicle, diagnosis, parts, and local labor. This is not a repair quote.
P3410 means the ECM commanded cylinder 3 to deactivate and the performance feedback didn't match.
How a shop works this
Work from evidence to part, not the other way round. A code names a circuit or a symptom; it does not name the part that failed.
Note every code that is set, not just this one.
Codes that appear together usually narrow the cause faster than any one of them read alone.
Read the freeze frame — the conditions the fault was recorded under.
Cold or warm, idle or load, road speed and engine speed. A fault that only appears cold is a different fault from one that only appears under load, even with the same code on the scanner.
Confirm the fault is current rather than history.
Clear the code and see whether it returns under those same conditions. A code that does not come back may have been logged during a repair, a flat battery, or a bad connection that has since been disturbed.
Then follow the diagnostic notes further down this page, in the order they are written.
They are written in the order a shop works this code, cheapest checks first. Where they name a component, inspect its wiring and connector before replacing it.
If the code comes back after a repair, the underlying fault is still there. That is the point to bring in a scanner with live data and freeze-frame, or a shop that has one.

Cheapest-first ladder
- confirm cylinder numbering and bank assignment for your specific platform before pulling any solenoid (Chrysler Hemi: cyl 3 driver's side, Honda J35 transverse: cyl 3 rear bank, GM LS-based V8: cyl 3 driver's side rear) — the wrong solenoid swap wastes an hour and leaves the actual fault in place.
- Ohm the cylinder-3 MDS/AFM solenoid (8 to 15 ohms cold), backprobe the harness for the ECM's 0.5 to 1.5A activation pulse, and scan oil pressure at the deactivation gallery during a commanded event (25 to 65 psi at 1500+ rpm minimum for clean lifter collapse).
- Watch the cylinder-3 misfire counter during the deactivation window — zero contribution is healthy, any spike means partial lifter collapse.
- On Honda J35 platforms specifically, scan the VTC (variable timing control) oil pressure feedback — clean rocker-arm reactivation needs 50+ psi at the VTC actuator, and dropping below that strands the cylinder in a half-deactivated state that throws P3410 plus misfire codes simultaneously.
- The expensive misdiagnosis: Chrysler 5.7/6.4 Hemi MDS lifters are the actual problem on 80% of P3400-P3424 codes — collapsed cylinder-3 lifter loses valve actuation entirely and presents identically to a dead solenoid, but pulling the valve cover and physically inspecting the lifter is the only way to confirm.
- Replacing solenoids without verifying lifters fixes only 20% of cases.
Vehicle-specific patternsChrysler 5.7L Hemi (RAM 1500 2009-current, Charger/Challenger R/T 2005-current, Grand Cherokee, Durango, 300C) sees P3410 most often during the post-…
Chrysler 5.7L Hemi (RAM 1500 2009-current, Charger/Challenger R/T 2005-current, Grand Cherokee, Durango, 300C) sees P3410 most often during the post-100k-mile Hemi-tick window when the cylinder-3 lifter is in the next-to-fail position behind cylinder 1. 6.4L Hemi SRT (392 Charger/Challenger, Grand Cherokee SRT, Durango SRT) compounds the failure with higher cylinder pressures. GM AFM 5.3L L83 (Silverado/Tahoe/Suburban 2014+), 6.0L (Avalanche/Yukon XL), and 6.2L L86/L87 (Silverado/Sierra/Tahoe/Yukon 2014+) throws cylinder-3 AFM codes during the AFM oil-pressure-relief-valve failure pattern — gallery pressure drops, lifters partially collapse, and the ECM sees an inconsistent deactivation event. Ford 5.0L Coyote VCT-i (Mustang GT, F150) throws VCT-equivalent codes on cylinder 3 when oil change intervals stretch past 7,500 miles and the phaser screen clogs. Honda VCM J35 V6 (Pilot, Odyssey, Ridgeline, Accord V6) cylinder 3 is part of the rear-bank deactivation group and is one of the most-failure-prone cylinders for the VCM-induced misfire spiral between 80K-150K mi — the rear bank cooks the spark plug, oil-fouls the rings during deactivation, and the cycle accelerates until the cat fails downstream; VCM disable harness at ~$120 is the common shop sidestep. Hemi lifter + roller cam rebuild runs $2,500-$4,500 parts + 12-16 hr labor.
