Question about 1997 Ford F150 Regular Cab
Engine light comes on
This is an airflow problem. Usually thought to be a EGR valve problem but the problem is the sensor not the valve. With OBD 2 you should have a DPFE sensor. (Delta Pressure Feedback EGR) that is a silver box with 2 hoses coming off the bottom that connect to the egr tube. That is the problem. Replace the sensor and your P0401 (that is the correct way to write the code as the P stands for Powertrain) will go away. The new updated DPFE sensor will be plastic and will probably require an updated connector. The connector should come with the updated sensor. And please use Ford Sensors.
