how do you tell / what are the symptoms of a bad m.a.p sensor . and is there a test like resistance test or anything to test the map sensor
i ask because i have a suspect map sensor

thanks!

 

anyone?

 

When I unplug mine, my car just straight up dies. Whether it be from the vaccume source or from the clip on the harness.

What EXACTLY is your car doing?

 

i have an extra map sensor off a perfectly fine car that i had rear ended. off a 90 crx si, lmk if u want it, 30 dollars + shipping. full map sensor on the firewall.

 

Usually the car will throw a code if the map sensor is bad. Also bad map sensors I have seen when they go bad will not let you rev over 3k rpm.

I have attached the Factory Service manual for checking out the MAP sensor. Gives the ECU pinout and the voltages you should be seeing.

Hope this helps.

 

thank you guys a ton
the reason i ask is my car bogs/sputters/missfires once it warms up . when it starts doing it i have to mash the gas or let up and it will keep doing it sometimes i turn off my car while driving and back on and it ill got away but sometimes not so thats y i think it a sensor and the only 2 i can think of that would cause this is map or tps

 

I have this exact issue with my honda accord 2003. I cannot exceeed 3krpm even when in park. Please where i do locate the MAP sensor in order for me to change it.

 

V6 = on top of throttle body - L4 = on intake manifold

 

Did you ever fix this? Im having the exact same problem right now.

 

Check your plugs/wires. I had this problem with my car having a bad wire and it'd only do it when the car was warm.

 

Check codes, usually it will sputter and be slow on uptake.

 

lol wow.... i thought i was going crazy , on why my engine wouldnt rev over 3k with a damn brand new s300 -_-
thanks!!

 

you cannot automatically assume its a bad MAP sensor unitl you test it.

sputtering when warm can be a ton of things
