Egr / Knock Sensor - Toyota Nation Forum : Toyota Car and Truck Forums

Camry-N-MD · 03-13-2005, 09:01 AM

My CEL came on lastnight so I took it to Advanced Auto. Codes were P0400...EGR Flow Malfunction. And code P0325...Knock Sensor 1 Circuit Malfunction. Went ahead and got prices for these parts, but what I really want to know is where are these located and how easy is it to replace them myself? I also heard that I could clean the EGR valve instead of replacing it. How is that done also?
If anyone has any pics that could help me on this that would be great !

that would tell you what you need to know about cleaning /removing it

for the knock sensor clean the egr and change your fuel filter and reset the ecu (pull the EFI fuse) and then drive it around till it trips a cel again then work from there

How about throttle/ carb cleaner? I just wanna know where I should squirt the cleaner, those hoses are on very tight. I dont wanna snap any of them.

So there's only two vacuum hoses to remove on the egr?
