Description
Aftermarket fuel rail / high-range pressure sensor (Automann 577.99532) for Caterpillar C7, C9, C11, C13, and C15 ACERT engines. Caterpillar uses the 284-2728 / 2842728 sensor for both fuel rail pressure and high-range oil pressure depending on the engine configuration; this Automann unit cross-references both Cat 284-2728 and 248-2168 with the same 3-pin Deutsch connector and 1/2″-20 thread.
Signs You Need a New Pressure Sensor
- Check engine light with fuel rail or oil pressure fault codes
- Hard starting, long cranking, or no-start conditions
- Loss of power under load or engine derate / limp mode
- Rough idle or engine surging
- Excessive black smoke from incorrect fuel delivery
