Bad MAP (manifold absolute pressure) sensor

Are you sure its not a Mass air flow sensor code, best re check, what code are you getting, ithink that Nissan's do not use a MAP sensor.

Two things. First, it falls under the vehicle's emissions warranty (100%). You shouldn't have to pay a cent to have it replaced. As far as location, it is on the throttle body.

my mechanic told me its not a mass sensor its a map sensor. but he can,t find the location

still can,t find it can you send me some kind of diagram

also does nissan altima 09 has map or mass sensor or both.

Looking at Mitchell 1 they show only 3 DTC's for MAF (mass air flow sensor) being P0101 P0102 & P0103 there are no codes mentioned for a MAP sensor, can you please advise the codes that the mechanic was trying to check out.

No idea about the code. In brief, I had a vibration (not shaking) feeling in the steering wheel..less engine power. My mechanic diagnosed it as the MAP SENSOR was not performing right...he couldn't find the map sensor location in my car. I don't get an engine light. Mechanic also said the mass sensor is giving perfect voltage and it's fine. If there is no map sensor in this car, doesn't know what it could be...as you can tell, this is very frustrating. Any tips?

go and get a new scan done , i need the codes, i can't do a lot with out them.

Also, I don't believe you have a MAP sensor. Again, if it is either a MAP or MAF sensor, they are covered under the vehicle's emissions warranty and should be done by a dealer. If he can't find the part (and I don't think it exists on your car), you really need to get a second opinion. Again, a dealer can tell you about warranty issues and the problem. And like Mark said, without codes, we are guessing.

Let me know what you find.

It says a bad Manifold Absolute Pressure Sensor but I can't find it on the car to replace it.

MAP sensor, not MAF sensor!!

They are calling MAF sensor here is the location f31. Here it is in the wiring diagrams that show the MAF sensor in the engine wiring daigrams.

Check out the diagrams (Below)

Please let us know if you need anything else to get the problem fixed.

I need the location of the MAP sensor! Not the MAF sensor!

Sorry the engine diagram above shows a MAF not a MAP. Even the hybrid shows MAF

No need to down vote I am showing you what they show me? cant do anything else but that.

Jacob says its on the throttle body. Can you check that out please?

Yep here is the location of the MAF please let me know if this looks like you engine.
