Map sensor help. need info on the 3 wies.
OK ive been trying to figure out what these wires are. I know that D17 is Signal, D19 is 5v power, and D21 is MAP ground. But i dont know which wire goes where so can someone help me?

map sensor yel/red = positive = yel/ grn at ecu = pin d19.
map sensor grn/wht = negative =grn/blu at ecu = pin d21.
map sensor wht = signal = pnk/wht at ecu = pin d17.
look at the pic. look like you got the plug for the tps not the map plug.
looking at the plug with the tap face up look like you are getting ready to plug in the sensor.
yel/red is on the left of the plug
grn/wht is in the middle of the plug
wht is on the right of the plug.
map sensor grn/wht = negative =grn/blu at ecu = pin d21.
map sensor wht = signal = pnk/wht at ecu = pin d17.

i know its a TPS plug. My new engine harness didnt come with a MAP sensor so i cut one off my old harness. so i just need to know what wires do what

grn/wht on the left of the plug
red/blu is in the middle of the plug
yel/wht is on the right of the plug
grn/wht at the plug = yel/wht at the ecu = d20
red/blu at the plug = pnk/blk at the ecu = d11
grn/wht at the plug = grn/wht at the ecu = d22
remember these pin out is for tps sensor. you can swap it over to the map pin out location.

you just gave me the pinouts for the TPS sensor. I put the wires to the spot where they were suppose to go and im still getting a CEL for MAP. ive tried every possible combination with them and i still get a CEL. <TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by 2lua »</TD></TR><TR><TD CLASS="quote">map sensor yel/red = positive = yel/ grn at ecu = pin d19.

Re: (JDMlyfestyle)
did you try to trouble shoot the map to see if the map sensor recieve the proper voltage? by the way did you try to swap out the map sensor?

Re: (JDMlyfestyle)
It is D17. The middle one will ALWAYS go to D17. The two outside wires are sensor ground and sensor voltage. If you got a CEL or it idles rough, switch the switch outside wires and it will fix it. This is saying that you have the wires ran right.
D19/20 = sensor voltage
D21/22 = sensor ground
D19/20 = sensor voltage
D21/22 = sensor ground
