Injen intake, CEL P0101 - Toyota Yaris Forums

remcafee · 01-02-2020, 02:21 AM

Anyone else have an injen intake and get a p0101 code with it? I tried cleaning the maf sensor and still getting it, I don’t think the sensor is bad, it all of the sudden came on as soon as I put the injen intake on, any advise is much appreciated!

Is there a baffle in the Injen tube before the MAF? The MAF is sensitive to flow, there have been a number of CAI that have triggered this code on the Yaris because the flow is outside the acceptable range.

The K&N intake has a shield welded in the tube that tricks the MAF.

I ended up getting an arm intake and it’s all good now, I don’t know why the injen wasn’t working, weird
