On a 2002 f150 check engine light is on with only 53000 miles?
* It could be a faulty check engine light or a light sensor problem . There's probably not a problem with the engine at all just the faulty sensor light problem most likely. * ----------------------------------------------------------------------------------------------------If your check engine light stays on with the engine running , a malfunction with the emission control system has been detected. Have your vehicle scanned for any trouble codes in order to diagnose and repair the problem. ( I had a check engine light come on at 35000 miles - in my case it turned out to be the DPFE sensor )

Check the engine sensors. I changed all the engine sensors on my 1996 Dodge Ram Van and it vehicle only started when I changed the Flywhel sensor on the bellhousing and it was also the cheepest sensor to buy. My auto mechanic scanned the on board computer but this did not show up the problem sensor. he had a spate of Chrysler group vehicles in with this same problem and it turned out to be the Flywheel sensor and for some reason Chrysler do not put this sensor into the on board computer checking system and did not show a fault code on the OBD.
Can anyone tell you why you may briefly get a check engine light when starting up The computer code says throttle positon switch but this has now been changed and it still does it?
