OBD-II Code
P3416
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.
P3416 means the ECM commanded cylinder 5 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 5's bank assignment (Chrysler Hemi: cyl 5 driver's side, Honda J35 transverse: cyl 5 front bank, GM LS-based V8: cyl 5 driver's side rear, Ford modular V8: cyl 5 driver's side front) — V8 cylinder numbering varies enough between manufacturers that grabbing the wrong solenoid is a real risk.
- Ohm the cylinder-5 MDS/AFM solenoid across the two pins (8 to 15 ohms cold = healthy), backprobe for the ECM's 0.5 to 1.5A activation pulse, and scan oil pressure at the deactivation gallery (25 to 65 psi at 1500+ rpm needed for clean lifter collapse).
- Watch the cylinder-5 misfire counter during the deactivation window.
- On GM AFM/DFM platforms specifically, scan the AFM oil-pressure-control valve commanded state vs feedback — a sticking OPCV drops the gallery pressure below the activation threshold and sets P3416 with zero solenoid fault.
- The expensive misdiagnosis: Chrysler 5.7/6.4 Hemi MDS lifters are the actual problem on 80% of P3400-P3424 codes — collapsed cylinder-5 lifter (a common failure on the Hemi MDS rotation) mimics a dead solenoid exactly, and the only real fix is pulling the valve cover and physically inspecting the lifter and roller.
- Replacing the solenoid on a failed-lifter engine clears the code for 50-200 miles then returns it.
Vehicle-specific patternsChrysler 5.7L Hemi (RAM 1500 2009-current, Charger/Challenger R/T 2005-current, Grand Cherokee, Durango, 300C) throws P3416 in the same lifter-collap…
Chrysler 5.7L Hemi (RAM 1500 2009-current, Charger/Challenger R/T 2005-current, Grand Cherokee, Durango, 300C) throws P3416 in the same lifter-collapse pattern as the rest of the MDS family — the Hemi tick from a collapsed cylinder-5 lifter is audible through a stethoscope on the driver's-side valve cover. 6.4L Hemi SRT (392 Charger/Challenger, Grand Cherokee SRT, Durango SRT) shares the failure mode. GM AFM 5.3L L83 (Silverado/Tahoe/Suburban 2014+), 6.0L (Avalanche/Yukon XL), and 6.2L L86/L87 (Silverado/Sierra/Tahoe/Yukon 2014+) is the most-frequent P3416 platform on the road — cylinder 5 sits on the driver's-side rear and is on every AFM/DFM deactivation cycle. The GM AFM oil-pressure-relief-valve failure drops gallery pressure below activation spec and the only permanent fix is an AFM-delete kit with non-AFM cam and standard lifters, $1,800-$3,200 installed. Ford 6.2L Boss V8 (F250-F350 SuperDuty, F150 Raptor) and 5.0L Coyote (Mustang GT, F150) throw VCT-equivalent codes on cylinder 5 from phaser oil-control-valve screen clogging. Honda VCM J35 V6 doesn't apply (V6 only has cylinders 1-6). Hemi lifter + roller cam rebuild runs $2,500-$4,500 parts + 12-16 hr labor.
Estimated repair$40 to $4,500.
