#16 of 65 Re: MAP sensor location in 2003 MPV [criledo] by hokiefan33 Apr 25, 2006 (5:40 am)
Replying to: criledo (Apr 25, 2006 5:13 am) Aren't these 2 sensors different? I know there is a MAP (Manifold Absolute Pressure) sensor, but is that the same thing as a MAF (Mass Air Flow) sensor? I know the '03 MPV has a MAP sensor on it, b/c I've already priced the part at AutoZone, and it is expensive, over $300 just for the part! Also, the code that came up when they checked it specifically referenced the MAP sensor, but didn't say anything about the MAF sensor? What do you think? If you can send a picture (of both sensor locations, if you have them, or just the one if that's all you have), that would be most helpful. I'm an accountant, not a mechanic, so things like this are tricky for me! Replies to this message: criledo (Apr 25, 2006 9:50 am)

Replying to: hokiefan33 (Apr 25, 2006 5:40 am) In that case I am the one that's mistaken, sorry, I thought you would have been looking for the MAF, not the MAP. I don't know the about the MAP, sorry! Why don't you go to the dealership, have them show you the part in the pats department and then ask them where it goes, they should point it out to you under the hood.....

Replying to: hokiefan33 (Apr 24, 2006 8:16 am) I think it will be easier if you listed the codes. Replies to this message: hokiefan33 (May 01, 2006 8:41 am) rogerrabbit (May 01, 2006 9:17 am)

Replying to: dtownfb (Apr 27, 2006 8:43 am) You're right, that might help, here they are:   1) P0174 - "PCM determined fuel system for Bank 2 was too lean." Possible O2 sensor? I believe there are 4 of them, right and left before and after the converter.    2) P0401 - "PCM determined there is insufficient flow in the exhaust gas recirculation system." EGR valve?    3) P0106 - "PCM determined that input from the manifold absolute pressor sensor or the barometric pressure sensor has changed too much, without a corresponding change in engine operating conditions." Possible MAP sensor, and that this may actually be the cause of the other 2 codes, as well (i.e. fixing this one might fix all 3)? This has the highest cost for the part, at approx. $339.'   Any help, and location description/picture of MAP sensor location, would be GREATLY appreciated!

Replying to: hokiefan33 (May 01, 2006 8:41 am) The MAS (Mass Air Sensor) is immediately after the air clear - essentially a round tube with a wire sensor in the tube - must be more than that because it costs several hundred dollars (which is why trying to clean it before replacing makes some sense).   Mine was replaced and drivability issues were solved - when the sensor is not working correctly, the bad readings send all sort of crazy fuel readings to the computer and cause the erratic performance. Not the only possible cause, but it was in my case (although I changed the spark plugs shortly thereafter).
#21 of 65 Error code P0442 by husker92 Mar 15, 2007 (6:07 pm)
States EVAP emmission Control System Leak (small).   On the web it says it could be the gas cap not on completely. It says to tighten it, reset the codes and see if it comes back (CEL). Can I reset the codes or does the dealer need to do that?   Any help would be appreciated.   Thanks - Jay
#22 of 65 2000 MPV PROBS by rickand2 May 01, 2007 (11:55 am)
I had check engine light coming on. At first I was told by 2 garages to twist the gas cap tighter after refueling. Turns out it was a valve a low compression in one cylinder. Very depressing after just 60,000 miles. I did maintain the car. It was not driven as a hot rod either. I would think twice before buying this year. I do not think Ford and Mazda used good sense before introducing this car.
#23 of 65 '02 mpv codes p0174,p0171,p0131 by boling Nov 11, 2007 (7:15 pm)
A friend's reader says it points to o2 bank one sensor one, where is this one located? do they have to be replaced in pairs?   Thanks,   Chris
#24 of 65 Error PO456 or P0456 by mvlyang Nov 19, 2007 (3:19 pm)
What can you tell me about this code? I'm not sure if the "O" is an O or a Zero. Replies to this message: subearu (Nov 19, 2007 3:43 pm)

Replying to: mvlyang (Nov 19, 2007 3:19 pm) P0456, or p zero four five six = Evaporative emission control system leak detected (very small leak)   Did you recently fill up the gas tank and forget to click the gas cap several times? Did you overfill the tank - ie, did you contine filling after the pump clicked off automatically? That can damage the charcoal canister system over time.   -Brian
