FAQ
Will this fit my 1998.5–2002 5.9L Cummins 24V?Yes. It’s listed for ’98.5–’02 Ram 2500/3500 5.9L ISB (24-valve). Verify by ESN and cross-ref (4921597, 3408430, Mopar 5080577AB).
What are the common symptoms of a failing cam sensor?
Intermittent no-start, stalling, rough idle, or cam/crank correlation codes. Always diagnose wiring/connectors before replacing.
Is a pigtail or adapter required?
Not when your factory 3-pin connector is healthy. If brittle or oil-soaked, replace the pigtail (compatible 3-wire harnesses are widely available).
How does this compare to a genuine Cummins sensor?
Interstate-McBee builds to OEM-equivalent specs at a lower price point. If you need a Cummins-boxed part, reference 4921597 (often superseded in listings by 5491993).
