Does my car even have a MAF sensor?
I am unsure whether or not my car has a MAF sensor. Can anyone show me where this is located? I thought if you have a MAP sensor you do not have a MAF sensor, well my car has a MAP sensor. 1989 Camaro RS Vert 350/T-5
Reason I ask is I got the code 33 thrown at me.

Probably not if it's not a tune port intake system. More than likely a tbi throttle body (looks like a 2 barrell carb).

Re: Does my car even have a MAF sensor?
If its an '85-89 TPI, then yes it should have one. If its a '90-92 TPI or any year TBI or carb, then no it won't have it.
If you have the '85-89 TPI mentioned above, then it will be 'spliced' into the rubber intake duct somewhere between the air filter housing and the throttle body.

Re: Does my car even have a MAF sensor?
Alright, so it is a TBI so there for no. So why am I getting an error code saying that my MAF is failing?

Re: Does my car even have a MAF sensor?
if you have a 350 then you have tpi not tbi.
the maf sensor is located immediately behind the throttle body at the juncture with the plenum. it is a wire that has to get hot so that it can measure mass air flow.
hope i said that right.

Re: Does my car even have a MAF sensor?
then its not stock - and air had it right between the air cleaner and throttle body.
every 350 came with tpi - look here https://www.thirdgen.org/1989-chevy-camaro.
so someone has made some changes to your setup.
you got it right AIR i was wrong on the location. senior moment.
maybe that is why you are getting a maf error - its the original computer ecm - and its looking for one because the programing says too.

Re: Does my car even have a MAF sensor?
From GM yes, but that was 20 years ago... maybe the 305 was changed out for a 350 at some point? Doesn't matter anyway, as far as his problem goes.
If you have a TBI setup (looks like a 2bbl carb) then you would want to get a trouble code definition list for a 305 TBI of whatever year your car is. Some lists will combine definitions (ie. XX code - _____ for TPI, _____ for TBI) even though it may not actually say "for this motor"... it may just have two different definitions, and you have to decide which one 'matches' the car.

Re: Does my car even have a MAF sensor?
i got a 92 camaro rs 3100 series motor, its throwing the error of the maf/map sensor but replaced the map and didnt fix anything. what could it be? when the clutch is engaged the rpms go up instead of down.
