Details of the Ford p1402 OBD Code
The Ford P1402 code indicates an issue with the differential pressure feedback sensor circuit.
Ford OBD code P1402 means the Differential Pressure Feedback Electronic Sensor (DPFE) circuit high voltage.
This code is triggered by the Engine Control Module (ECM) when it detects a high voltage signal from the DPFE sensor.
The DPFE sensor is part of the EGR (Exhaust Gas Recirculation) system and is responsible for monitoring the exhaust gas flow.
When the ECM detects a high voltage signal from the DPFE sensor, it indicates a potential issue with the EGR system, such as a clogged EGR valve or restricted EGR passages.
Mechanic’s Tech Notes
Detailed information on diagnosing and repairing Ford code P1402 related to the differential pressure feedback sensor circuit.
To diagnose and fix OBDII code P1402 in a Ford vehicle, start by checking the Transmission Control Module (TCM) power and ground using a multimeter.
Verify TCM communication over the Controller Area Network (CAN) using a scan tool.
If the TCM does not respond, reprogramming or reflashing may be necessary.
Additionally, visually inspect the wiring harness and connectors for any damage, and ensure connector pins are not broken, bent, pushed out, or corroded.
Addressing these issues can help resolve the P1402 fault code.
