Okay so ever since i put this f 150 on the road in September I've been getting my check engine light flashing on randomly, but now that I have double checked my emissions hoses im getting them more frequently, so I got off work early today and when I got home with the light on I decided to grab some speaker wire and check these codes.
im sure there are parts of the test that I missed, such as the dynamic part, and I know I missed at least one code near the start of when I started counting, so here are the results im 75% sure I counted correctly.
52 Power steering pressure switch circuit is open or not changing
77 dynamic test not performed due to no input from driver.---obviously this is my fault.
33 EGR Valve Position (EVP) sensor or Pressure Feedback EGR (PFE) sensor indicates EGR valve is not opening.
or, EGR Valve Position (EVP) sensor or Pressure Feedback EGR (PFE) sensor indicates EGR valve not seated (closed) properly.
41 Exhaust Gas Oxygen (EGO) sensor: voltage signal always “lean” (low value) – does not switch.
51 Engine Coolant Temperature (ECT) sensor – signal voltage is too high.
okay for 52 I know that my powersteering box has a leak and has gotten pretty low so no surprise there.
for 33 ... now when I was looking at my emissions hoses, there is a large hose with a metal fitting on it that sits on a metal line that connects to the manifolds somewhere. since I put it on the road that metal fitting was not sitting on that hose, I plopped it on and the truck quieted down, and ran a fair bit better, (also after seafoam) now i've been trying to find this out cause all of my engines that i've been running previously have been stripped of emissions equipment, that metal "fitting" is that my EGR valve? and is it supposed to be secured to something so it doesn't move? if I floor the engine you hear a small whistle and then the engine runs louder because the metal " fitting" gets pushed off. that may also have caused this code.
and for 51, my temp gauge has never read right, it sits at just barley over the low part of the normal range, and when it did eventually reach the middle of the gauge, my truck overheated.
