ok guys, today my cel came on for map sensor. its idling horribly and jumping.

if i turn the car off and clear the code and turn it back on the idle is around 500 and sounds horrible.

I need to know if there is any way to test the map sensor. These things are expensive, in fact a new map sensor would cost me more than i paid for my entire motor!!


also, could the o ring (gasket) be causing this problem? its flattened out pretty bad and has little notch taken out of it.

any other suggestions would be awesome as well.

 

have you reset the ecu?

 

fastest way to test you map sensor is take it off your car.. connect it to a friends car with a vacuum line (leave theirs on the throttle body) and unplug their map and plug in yours.. see how their car runs..

 

i dont htink that will be a possibilty. i might be able to borrow one. but doubtful.

btw, whats the diff between a code 3 map sensor and code 5 map sensor?

same thing? or does one mean a diff problem with the sensor?

 

same thing.. don;t have any hondas to test it on?

 

ok i have a 96 modle d16y7 swapped into my rex and im gettin a code 5 which is the same as code 3. but my map sensor is hooked up i dont know what else it coud be

 

A map sensor can be bought at a junkyard for $10-20 if you look.
Your problem may not be the map sensor. It maybe your wiring or you may simply have the tps and map plugs mixed up.

 

same here my car will jump alot so i left the car running unpluged the sensor and it stalled so idk it looked a lil dirty so idk if i can clean it or somthing? does any one no if it's possible to clean or if cleaning it will help at all?

 

i got a new sensor off ebay, but i just hooked my old firewall mounted map up temporarily. it is running fine now. map sensor was caput.

 

thats good how much u pay for it ?

 

What did you find out about your map sensor?

 

I have a few problems with my 93 EX civic. It will idle high when first started and my check engine light come one when I hit around 90MPH. I know the vtec isn't working. what can you tell me this is my first time.

 

you need the code...there is a sticky at the top of the forum with a how to on checking codes and what they are. and stop doing 90 mph, no need to go that fast

i paid 12 bucks for the map sensor btw. works like a charm now...well the map sensor does...still got a weird idle that i have yet to find..

i think it has something to do with this sticky *** STR throttle body

 

I got a D15B swap running with the JDM computer .. im having problems with Code 3 MAP sensor!!! when car in on and i plug the map sensor In car shuts off.. when map sensor is not plug the car turns on and runs rich and stall.. i mean ive put 2 different map sensor and same.. please help help help!! thanks guys.. ??????

dont steal the thread...

 

this thread should be dead, ive fixed the problem.

everyone else make your own

 

clean the map sensor out with starting fluid or some high octane gas. its probably carbon build up. but that should do the trick. if it needs to be replaced $25 at the junk yard. or it could be ur o2 sensor.
