TRD Intake Second Gen, P0101 Code

What happened once you disconnected the battery to reset the ecu?

 

Update:

Reset ECU by disconnecting battery- Still getting ECU codes P0101.

Toyota said the reason was the MAF wasn't seating right and it was sucking in air.. I sealed it with gasket maker, pressure tested it up to 20psi, no leaks after sitting for 4 hours. Ran the truck, still got the P0101 Error Code.

So for now I have put the stock intake on to see if it is the TRD causing it or not. After speaking to Gadget at URD he said the P0101 isn't a typical code that the TRD intakes throw and I may have some other issues.

I also got the URD MAF calibrator to see if that will also help fix the issue.

 

Update: Stock intake throws no codes. Damn.

So I have the URD MAF calibrator, just debating if I want to install since it will void my Warranty.

 

1st Gen TRD intake installed.

1. It is a hell of a lot louder than the 2nd Gen during WOT
2. Looks better
3. I have not got a CEL yet
4. I still think the 2nd Gen had a bit more pickup according to my ass dyno.

So the difference between the two:

The maf is located closer to the air filter in the 1st gen
The vacuum line is in front of the MAF on the 1st gen, on the 2nd Gen its past the MAF near the throttle body.
Tubing is thinner on the 1st gen and a bit longer since the air box is smaller in size.

I'm wondering if the issue is with the vacuum line being behind the MAF on the 2nd Gen?

On my Torque app I'm showing that it isn't running lean vs. the 2nd Gen.

Guess its time to sell that second gen. Funny thing, doesn't throw codes on my dads 08 or my mom's 05 Tacoma's. They both ran it for a month, no issues..

I've been fighting with Toyota HQ about this 2nd gen intake. They state 'since there was no recalls we can not help you with this intake issue you are having". Worthless.

Was this ever resolved? I installed the TRD CAI and started having this problem in really cold weather.

 

By swapping to a first generation TRD intake it fixed my issues.

 

I had the same issue when I installed the 2nd gen CAI in my truck. After it smogged it threw p0101. I had no issues with an AFE Stage 2 or stock airbox. I also noticed the location of the vacuum line being behind the MAF. I am going to attempt to relocate the vacuum line ahead of the MAF and see if that resolves the P0101 issue.
