P1406 FORD -

Question

Just threw a service engine soon code of p1406. I replaced the dpfe sensor and cleared code. It popped back on after about 10 miles. I cleared the code again and am waiting to see what happens. Any ideas?

Answer 1

you will need to check for carbon build up in the intake it.blocks port to egr value and causes dpfe to read running lean ..will throw code every time ..theres a hole inside throttle body. .coat hangers work great some air and carb cleaner should do trick..good luck
