I meant, the end of it is pretty large. I don't know how I would manage to connect something to the end of it, but I will figure something out.Bob Lincoln said:You would remove it to test it. But you can probably leave the electrical connector plugged in and use your pump on the vacuum port.
A code 32 can be triggered by a perfectly functioning EGR valve, if the orifice under it gets clogged shut with carbon buildup. This is a common problem on Toyota 4-cylinder engines with high mileage. The carbon hardens so much that it has to be drilled and scraped out, not just dissolve with carb cleaner. If the idle does not change or stumble when you lift the EGR stem up with a pair of needlenose pliers, the orifice is plugged.
Note that this situation does not cause any poor operation, just the code.
I manually actuated the EGR at idle with my hand vacuum pump. It caused the engine to stall out immediately before the diaphragm in the EGR opened all the way. I kept vacuum applied for about 1 minute to confirm that there were no leaks in the EGR. Also, when I replaced it, I looked into the passage. xcept for a minor coating of carbon inside, the passage was clear. Which is why I am so confused as to why it keeps setting the EGR code. :frusty:
