Description

When your newer John Deere starts throwing emissions codes or goes into limp mode, it’s often this little sensor that’s causing all the trouble. The differential pressure sensor monitors pressure differences across your tractor’s exhaust aftertreatment system – the DPF filter and SCR system that keeps emissions clean. A faulty sensor can shut down your tractor right in the middle of harvest or planting season, making this a critical part you don’t want to ignore.

What You’re Getting

Precise pressure monitoring that keeps emissions systems functioning properly
Direct replacement that restores accurate readings to your tractor’s computer
Sealed construction that withstands exhaust heat and vibration
Quick response time prevents unnecessary regeneration cycles and power derates

Built for Real Farm Work

This sensor fits a wide range of John Deere’s modern emission-controlled tractors from the 7020 series utility tractors through the big 9020 series 4WD machines and the newer 8R series row-crop tractors. Whether you’re pulling a planter with your 7820, running a big disk with an 8330, or working ground with a 9520, this sensor is what tells your tractor’s computer that the emissions system is working correctly.

Made to Last

Modern emissions sensors live in one of the toughest environments on a tractor – right in the exhaust stream where they deal with extreme heat, soot, and corrosive exhaust gases. This replacement sensor is built to handle those conditions while maintaining the precision readings your tractor’s computer needs to keep everything running smoothly.

Good to Know

Installation typically requires getting under the tractor to access the exhaust system, so make sure everything’s cool before you start. The sensor threads into the exhaust casing and connects with a weatherproof electrical connector. After replacement, you might need to clear codes and let the system run through a calibration cycle. If you’ve been having frequent DPF regeneration issues, this sensor could be the culprit giving false readings.
