What It Helps Address

• Fault codes related to exhaust backpressure sensor signal loss
• Rough running caused by inaccurate exhaust pressure readings
• Reduced engine performance from a failing sensor
• Emission system monitoring issues tied to pressure feedback
• Hard starting or drivability concerns on diesel engine management systems

Installation Notes

Verify the connector style, mounting location, and application match before installation. Compare the original sensor to Walker 1002-1003 and confirm vehicle-specific service information for Ford F-250 and Ford F-350 diesel models. After installation, clear diagnostic trouble codes and recheck system operation to confirm the exhaust pressure signal is reading correctly.
