FAQ

Will this fit my 1998.5–2002 5.9L Cummins?

Yes, this sensor is for the 24-valve ISB used in 1998.5–2002 Ram 2500/3500. For edge cases, confirm by VIN/ESN and the OEM reference 4921597.

Do I need to program anything after installation?

No programming is typically required. Clear codes and verify operation after installation.

What if my truck still cranks a long time after replacing this?

Inspect the crankshaft position sensor, battery/ground health, and fuel supply (lift pump pressure). Wiring integrity at the timing cover is also common.

Is a new O-ring included?

Many sensors ship with a seal; if not, reuse a serviceable O-ring or replace with a new one matching the OEM spec.
