About my Previa and Sienna

 Yes!!!!! P0171, P0130, P0133 kept popping up on me.  Initially, I thought it was my front heated 02 sensor, but after looking at the sensor, I realize it was the one that was replaced. So, I looked at the intake are really quick to see if there was anything I might have forgotten. BOOM. Looking under the driver's side and I find one of those tiny hoses had come off the fitting and it was part of the intake. It was easy to miss as it is all part of those tiny hoses all jumbled in there. It has been a few days and no code reappearing!!! ------------------------------------------------------------- I had the infamous P0401 - EGR circulation. So when I did the EGR clean out, I did not erase the code and was gonna have the shop see if they would find the issue, but never brought it back to them for that issue.  But I cleared it and ever since then, it has not popped up!!!

Well... it came back and bit me. When the motor was being rebuilt, the transmission was out and I was going to take it to the transmission shop to have it inspected. Since I could not get to the shop in time (work and school), I just had the shop change out seals and gaskets. I was also told tranny was good. Well, after some basic research, I found out the S/C previas had the same transmission as the supras, which means they were beefier transmissions. So I had a false sense of "it should be okay". WRONG. A weeks ago, there was a noticeable long delay going into the lower gears. Then it got progressively worst with a sudden hard shift in to 2 and 3 gear. I had about enough of it. I took it to the shop that did my motor (and it has been a few months) and they said it feels like the clutch packs in the first couple gears is going out and that maybe the internals are damaged. I thought about it and took it to a transmission shop (the one I originally ...

After I got my van back and was enjoying it, a check engine light came on. I brought it back to the shop and they mentioned it is a code p0401, which was Exhaust Gas Recirculation (EGR) system flow is insufficient. They said it is no big deal and not to worry about it. (For some reason I didn't like that). They said it wasn't anything and honestly, I think this was linked to the plugged EGR port THAT SHOULD HAVE BEEN LOOKED AT AND CLEANED while the motor was apart. So I honestly lost faith in the shop.I didn't like how they said they are gonna see what parts that are needed and get me prices.  I decided to follow Zenseeker's tutorial and it was true to form. My EGR port was plugged. I cleaned it out and kept the check engine light on as I was going to give the guys my van to check again, but decided not to. After while, I picked up a scangauge II and hooked it up. I get 3 codes!!!!! P0401 P0133 P0130 so I looked them up. What could cause the code P0401...
