Question about 1991 Ford F250
How do i fix this this problem. I have replaced the egr position sensor already , ck valve for operation, ck to see to see if egr passage is clogged up. everything seems to be working
There is a little aluminum block with 2 hoses on it that goes to the exhaust manifold. If you take that sensor off and replace it, that will fix your problem. it's called a PFE sensor. They get corroded up inside. Make sure you clean the hoses out when you replace the sensor and hook them up the same way you took them off. Don't cross the hoses. Hope this helps. Phil
