Coupe V6. I have a P0401. I have replaced the egr valve, modulator, and the vsv and still have this code popping up.
JA: Many things can cause a car to make those weird sounds. Some simple, some complicated. Fortunately, the mechanic I'm going to connect you with knows all the tricks and shortcuts. Tell me a bit more about what's going on so he can help you best.
Customer: When press the gas and accelerate quickly I smell carbon
JA: Are you hoping to fix this yourself?
JA: Great! What have you tried so far?
Customer: I've cleaned the plenum, where the egr valve connects. It continues to get clogged at that location
JA: Is there anything else the Toyota Mechanic should be aware of about your Toyota?
Customer: Everything works great
JA: OK. Got it. I'm sending you to a secure page on JustAnswer so you can place the $5 fully-refundable deposit now. While you're filling out that form, I'll tell the Toyota Mechanic about your situation and then connect you two.
