Would anyone on here happen to know the location of the Manifold Absolute Pressure Sensor on my '06 Elantra? Thanks for taking the time to read this.

 

Hi Dan,
Would you mind telling us why you are looking for this part's location?

Maybe we might be able to save you some trouble if you provided the requested info.
It should be located next to the throttle body.

 

Sure Hanky,

It started as a severe miss, especially when accelerating as well as erratic RPMs when I started it. Check engine light indicated it was the TPS, so I replaced that. Seemed to work for about 5 miles, then the miss came back. I parked it and came back the next day and it was even worse; I couldn't even get it to go over 2k RPMs without a stall out. I read around and couldn't find specific solutions so I:

Checked my plugs and wires -all good
Cleaned the Mass Airflow Sensor and throttle body -didn't work.
Replaced the MAS- didn't work.
Next step I'm thinking it could be the MAP sensor

Any suggestions or tips would be greatly appreciated!


edit: I forgot to mention, it idles and revs okay when in park despite the rpms being a little erratic. (I really thought it would be the TPS based on that)

 

Dan,
as you have learned by this time shooting in the dark can get a little discouraging and expensive too.

If the severe miss as you describe is coming from one cylinder, you would confine your efforts to that and what can affect that cyl.
What we don't know at this time is which cyls are involved.
How was it determined the TPS was the fault?

Places like Autozone will check your vehicle for any codes at no charge, just be careful before buying anything and make sure it is a component problem and not something related to that circuit.
Crank sensors don't usually give a code , but if with problems will affect engine RPM readings and performance and since the RPMs were mentioned , might be worth looking into that part.

 

The TDS was found at fault at a parts store (O'Reilly). To be frank, I am not a "car person" -I've just been trouble shooting with google and my father (who rebuilds VWs).
I'll take a look at Crank Sensors then. DO you have a source that you would recommend me to read up on them? Thank you again, hanky!

 

Vehicles usually have either a MAP or MAF sensor.
If your vehicle has a MAF sensor then it probably doesn't have a MAP sensor.

If you believe this misfire is a single cylinder misfire (can be seen on a scan tool that has live data available .. around $100 to $300)
Find out which cylinder it is. A power balance test can help sometimes. (Or, check the scan tool)
(With the scan tool, check the short and long term fuel trims.)
Running lean or rich? Inspected the spark plugs?
Were they fouled? and the gap is enlarged??

On my Elantra 2001, I had a misfire on cylinder 3.
It was caused by a vacuum leak
Turned out to be the intake manifold gasket.
The gasket was only a few dollars. But, the work involved too hours.
Try spraying carb cleaner or brake cleaner around the intake
The result will be the misfire will either get worse or better when you get the right place
Note of caution when doing this. You don't want to hit any electronics or hot spots.

Good luck
