codes

[hcalero33]

im new here I need some help I got the 2.4 in a 01. the codes I pulled are p0100, p0101, p0102 just need help on figuring out what is wrong. I looked up the codes they all relate to the maf sensor with when I look up maf sensor for the 2.4 I get nothing. help please

Are all the wires intact?

Had an IAT sensor code to find one wire was broken. Had to order a new connector

Where on the 2.4 is the maf at

[sleepyalero]

Doesn't have one i believe.

[hcalero33]

Then whyy would i get codes for one??? Im totally lost...

[sleepyalero]

Sorry maybe its the 2.2 that doesnt have one? Im not sure im a v6 guy. Someone will chime in.


A maf sensor is connected somewhere on the intake. Usually pretty close to the throttle body..

[hcalero33]

well I cant find one for the 2.4 so my guess it does not have one I have pending codes for the map sensor so im checking around for vacuum leak
:panic:

[hcalero33]

the shop that did smog on it said it could be the catalytic converter

There is a short section of vacuum line that runs from the throttle body to the map sensor. On my friends it was falling apart and could be your problem. If not it could still lead you to the sensor.

Oh MAP Sensor???

you said MAF sensor, with an F, not a P.


Yes the car has a MAP sensor, but not a MAF.

[aleros_eat_rice]

MAF= mass air flow
MAP= manifold absolute pressure

All V6 Aleros have both, but the twin cam and ecotec Aleros use the MAP sensor to check air flow.

On the 2.4, there is an IAT (Intake Air Temperature) Sensor that is plugged in to the intake piping after the air filter, before the throttle body. There are also some vacuum lines near the throttle body that were cracked on my 2.4. They were pretty simple to replace.
