Thanks. Between you, scanner danner, wells, go tech, fordtechmakuloco, and that russian guy with the adhd (haha, I have learned a ton. Recently I got a hantech scope. I have learned to graph with our snap on solus and save the files to a pc desktop for study at home. I got a killer ford explorer with the same symptoms as a taurus you worked on that I can't figure out. I am not even sure if its a misfire, an engine airflow problem, or maybe even a transmission problem. EEEk. On the Caravan we have in our shop now, I did all of what you have done here and everything was good, so I put in an egr valve. It did not respond so I cleaned the old one and re plugged it in and it did respond at least some. Its a made in china part bad right out of the box is what it is. You buy two egg rolls and you buy two egr's. My usual google search would be something like tps repair south main auto. In the last month I nailed three correct diags for pcm replacement. I got a buick enclave or whatever it is to work on tomorrow and it has a key code p3055 and a no communication with ecm u0100 and I bet I know what direction, as you say, to go. Description of operation first and code setting criteria second. I learned this from you. Thank you sir.

I have a 2005 Pacifica that is throwing a p0404 that the dealer's mechanic can't fix (I just bought this car and the last time their 3rd party mechanic tried to work on it, they had it for 3 weeks and called me to come get it as they can't fix it and are refusing to work on it anymore as the dealer isn't paying them after multiple misdiagnosed fixes, including replacing the cat. One quirky symptom is that the code will sometimes clear when I gas up the tank. I got it to clear one time just by taking the cap off and putting it back on again. The clear on fillup only works when the system is cold. Someone mentioned to me about a similar problem in Nissans that requires dropping the tank to fix. Also, this Pacifica has the problem of the saddlebag gas tank going from half full to empty (something about a crossover pump or hose not working or plugged so it's not transferring gas to the pick up on the top half of the tank. Does this sound familiar?

I would love to get ahold of one of these DRB III tools, it's the ONLY thing capable of reading my 1995 Chrysler Cirrus (OBD-II style connector) but pre-1996 with a proprietary protocol. So that only Chrysler can read it. Tired of paying the 100+ hookup fee for their convenience of testing. Every time I look in the service manual for testing procedures, step 1 is Hook up DRB III diagnostic tool.
Is there a way to know if a tool like the Autel can connect?

Idk if I'll get a response but I have a 2000 Dodge Grand caravan. Where everyone sees the cgr valve is I see a coolant resavware. Now I know I can be slow sometimes. But pleas tell me I can do this and not have to take it to my machanic. I literally can't even see the EGR valve! And this van has bin taken care of really good. This is my second car in one year. She needs love and I can't afford a toe.

On my 2006 Dodge Caravan I change my EGR and it was ok for awhile and code came back, so put in a factory EGR. And that lasted for two weeks brought to a shop like yours and he said it was a block exhaust system that was making the EGR. Act up, found the. Blockage in the cat replace it been good ever since.

How can a person bench test that EGR valve 2005 town and country? Can a person supply 12 volts directly to the solenoid wire (6) and ground (4) to the body? Would that cause the valve to open, just to check to see if the valve opens or not? I am wondering how could I bench test it?

Replaced a egr just 4 days ago. Volkwagen Routan aka ''Caravan''. egr tps voltage at 4volts flat, 0% duty cycle with the new one. 3. 8volts is what i got for the bad one. Symptoms was: intermitent stalls at low speed, loss of power steering and code C121C in abs module.
