New check engine codes!!!! I hate you!

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

- clogged or restricted EGR passages (This is what I believe it is)
- faulty EGR valve
- EGR valve stuck closed
- problem with the EGR vacuum switching valve (Toyota)
- clogged catalytic converter
- carboned up EGR temperature sensor
- vacuum supply issues at the vacuum-operated EGR valve
- electrical problems with the EGR valve control circuit
- engine computer problems

What could cause the code P0133

 - Faulty Front Heated Oxygen Sensor Bank 1
- Front Heated Oxygen Sensor Bank 1 harness is open or shorted
- Front Heated Oxygen Sensor Bank 1 circuit poor electrical connection
- Inappropriate fuel pressure
- Faulty fuel injectors
- Intake air leaks may be faulty
- Exhaust gas leaks

    Do you have any updates about your van? With the check engine light, three codes can connect to dozens of problems. Advanced computer diagnostics correctly identify check engine light issues so make sure you are using a trusted resource. Good luck with your auto repairs!

EGR system Clean out and Code P0401

EGR system clean and Code P0401 This is another MUST DO on the previas, especially if you are having issues and code P0401 being thrown. P0401 is "Exhaust Gas Recirculation flow insufficient detected".  Parts: - EGR intake gasket - 25628-76010 - this is on the far right side next to the exhaust. - EGR valve gasket - 25627-76010 - used for the EGR valve to the intake manifold.  -Air inlet duct gasket - 22273-76010 - this is where the air goes into the intake manifold and where   the EGR port gets plugged. 1 container of coolant I did buy a set of crow's feet and Universal joints for the Exhaust pipe. I followed Zenseeker's photo's on every single detail. If you haven't visit his website (http://zenseeker.net/Previa/PreviaMaintenance.htm), it is a treasure trove of information!!!  Zenseeker gets the credit and this would have been impossible for me to do without those pictures! **The pictures are located at the bottom of this po

I GOT A COOLBOX!!!!!!!!!!!!!!

I found out that the previa had a "cool box", which is like tiny fridge under the dash in the middle, from Toyotavantech. I have seen them only in photos and in Canadian spec previas (unsure if they were in US spec). Even our owner's manual has some mention of them. Often times, I would look at CL in Vancouver BC in hopes someone wants to sell or part a van with it. Now, I've seen a few different versions, in which I don't have the ones that are pictured below. (note, these cool box images were found on the internet). A slanted shape one  This is a cool and hot box, 3 buttons on top ------------------------------------------------------------- I've kinda looked at the cool box as a Holy Grail. 9/12/15, Saturday. After volunteering my morning at the farmer's market making boxes and putting fruits and vegetables for low income families (Phat Beets Produce!) here in Oakland, I went to go fill up gas in

EGR, IAC Valve, Throttle body, black flakes in the coolant....

Before I get into this, let me give proper thanks for the info and pictures from zenseeker.net, toyotavantech (theMan) and Uri of Previadiaries.wordpress.com These sources really put pictures and what they did out there.. so now I 'm going to jumble them all together as I am going to do these cleans soon! ---------------------------------------------- After spending a pretty penny and 2 months having the motor rebuilt. I kept reading about the black flakes in the coolant.. I mentioned this to the shop that I had my van worked on. At on point, I asked for the throttle body  and IAC valve as it was just sitting there, but got the "dont worry about it, we'll take care of it". I even showed some blogs of that covered this issue. After getting the van back... boom, check engine light and the shop ran the code. In all honesty, I was kinda upset that they did not cover this part, even after I had mentioned it.  P0401 Error Code : "Exhaust Gas Recircul
