Product Description
CUMMINS 6456801 OEM ENGINE OIL PRESSURE SENSOR (EOP) – RAM 6.7L (2007.5–2018)
The genuine CUMMINS 6456801 engine oil pressure sensor (EOP) provides the correct pressure feedback your 6.7L Cummins requires for proper ECM operation, safe engine protection, and accurate dashboard readings. A failing or inaccurate oil pressure sensor can trigger false warnings, reduce engine performance, or fail to alert you during a real low-pressure condition—making OEM sensor integrity absolutely critical. This is the same sensor Cummins installs at the factory on ISB 6.7 engines from 2007.5–2018.
With precise calibration and high-temperature–rated internal components, this Cummins EOP sensor maintains accurate pressure monitoring even in severe towing, high-duty, and commercial-use environments. Whether you’re repairing an intermittent gauge issue or performing a complete top-end lubrication refresh, installing a genuine Cummins sensor ensures reliable readings and proper engine protection logic.

Frequently Asked Questions
WILL THIS FIT MY 2007.5–2018 RAM 6.7L CUMMINS?
Yes. The CUMMINS 6456801 sensor is used across most ISB 6.7 applications from 2007.5–2018. Because of calibration changes, always verify by VIN/ESN.
WHAT SYMPTOMS INDICATE A BAD OIL PRESSURE SENSOR?
False low-pressure warnings, erratic gauge readings, hard starts, incorrect derates, and stored EOP-related trouble codes.
IS THIS A GENUINE CUMMINS SENSOR?
Yes—CPP Diesel supplies only authentic Cummins OEM components for 100% correct fitment and calibration.
DO I NEED TO CLEAR CODES AFTER REPLACEMENT?
Yes. The ECM may store EOP-related fault codes that require clearing after installing a new sensor.
