I get a code 71 on my 22rec, I replaced with new, EGR valve and the EGR temp sensor( cali only). I am going to check the EGR vsv at lunch per the FSM. I am wondering if the pasage in the head is clogged? Anyone know if you can clean it with the head on the truck? Next will be the intake plenum as well. Thanks in advance to any EGR gurus.

I just checked the VSV and it test within spec. Next I am going for the plenum and see if I have any air flow there.

The passage in the head is flowing,valve is working ,vsv works,passage in the plenum is flowing. Either my new temp sensor is bad or I have a problem to the ecu. Is there anything Im missing?

does that motor have an egr transducer like the 3.slows, i was having an egr issue with my 94 runner and it turned out to be the transducer

diablo

I do not think so, but describe transducer

about 2 inches in diameter, 1 vacuum nipple on bottom, 2 coming out of the side, bottom nipple goes directly to egr valve, other 2 route around to a vsv (i think thats the name) at lunch ill go out and take a picture and attempt to post it

I think your talking about a egr vacum modulator, atleast on a 22rec thats what its called. I have installed a brand new one. Keep the ideas comming

that temp sensor for the egr valve, one of my yotas had one one didnt, the one that didnt had like a cap on the plug to close the circuit or something but when i remove that cap i got a code 71 put it back on and no code 71. im not sure where to get them, but give that a shot if ur still having issues
