Injen Intake Issue

Mass Air flow sensor... You're gonna have to find a way to trick the computer into thinking everything is normal...

 

According to @Georgina Rudkus, that injet intake is suffocating the car and you should remove it completely for best performance. Should have saved the money by not buying it.

If you find a way to spoof the sensor reading so it's back within parameters and no longer throws a code, let us know.... Would be good info to know.

 

You replace stock filter and intake, then try conning the car into thinking you still have a Mass Air Flow sensor, and it's within parameters. This is the MAF sensor that the car's computer uses to adjust the fuel injector spray. Am I the only one thinking this is not productive?

Or is that not part of the equation, lol.

 

Both my husband's older friend and I have installed the HPS short arm air intake on two Prius v's, my 2012, and his 2017. My husband installed the equivalent HPS intake on his 2016 Nissan Versa Note.

While this is not the INJEN intake, all three intakes each using the HPS with a K&N filter for the past two years, have worked perfectly with absolutely no CEL activation.

 

Never said it. The resonator or pre-intake on the OEM filter is restrict on the flow. A non-restrictive air intake like the HPS is even better.

 

Each HPS intake was around $180 delivered. The INJEN is $230-240+ delivered.

It just proves that price is not always an indication of function or quality.

Although INJEN intakes might be C.A.R.B. listed, HPS chose not to spend the cost of certification as it is very expensive.

That does not mean that it would not pass, if it was submitted for certification.

My experience with HPS is that the quality of the components, bends and welds in the tubing is exceptionally high quality.

 

As much as I can glean: a Mass Air Flow sensor is used to precisely measure the air flow, and reports this to the car's computer, which in turn optimizes the fuel injectors with this info and various other inputs. If you've disconnected the MAF sensor, the care is running less than optimum, at least partially in some sort of fail-safe mode?

You're likely either burning lean or rich, and neither is good, for the engine, or the environment.

 

I search the web for the Prius INJEN air intake and found it to be a little more complicated than the HPS. I uploaded a photo of the INJEN installed.

 

Here is a link to the HPS on Amazon and my husband's friend's review.

 

It should work. I'd call Ingen and ask them about it. You can see where the mass air sensor is the tube is smaller. Probably close to stock size.

I'll stick with the HPS. It also eliminates the rat-mouse home.

The freed up space of the OEM filter and housing is ideal for the Ruien oil catc h can.

 

There less drastic ways to rat proof, a bit of mesh over the intake.

Appreciate I'm the "thorn" here...

 

Clean your MAF and make sure you plugged it back in. A loose connection is the most likely issue.

I have had an Injen on my Prius for almost 2 years now, no CEL, better pickup, better sound, less clutter in the engine bay.

 

There's a place for the MAF sensor?

 

What kind of question is that? How else would the car run? Of course theres a place for the MAF sensor.
