Can you explain to me the vacuum pull test? I have been trying to find a way to test if my egr is working or not as I have a code 71 as well.
The manual, if I recall correctly, calls to check the egr, followed by the temp sensor. The only issue, is that my manual shows the egr as electric and not traditional.
Let me know please, thanks!
I just used a clean tube connected to the top of the egr and sucked on it while engine was running. engine stalled immediately. based on what I've read, that proves egr to be good. you could also just use the tube already connected, just disconnect the other end.
