jdm_xsi206

anyone?

jdm_xsi206

no one?

Before the flaming begins, I'll just give ya a heads up...

Anytime when asking for information on how to fix something it's always in your best interest to list your car year make and model, your motor, and what all is done to it... And if you have CEL's list what they are because not all of us remember our codes off the top of our heads...

jdm_xsi206

aight thanks for the heads up.. Ok so i have a four door eg wit a mini me swap (d16b5 block with a z6 head also has an aem cam gear). I am thorwing the map sensor code which is 3 and 5. Then im thorwing tps and thats the code 7. Andi forgot what the code 43 is. But i do know that i deals wit the fuel system. So how do i fix them?

jdm_xsi206

so the code 43 is the fuel supply system. I have no idea what that is

JDM_SOHC

No doubt bro, I'm one of the cooler ones on here but some of the HT douche-bags like to come and spread their shitty day on others so I just figured I'd give you a heads up before a few of them flocked in here...

Anyways, Code 43 is Fuel System related, but could also lead to a bad o2 sensor (throwing mixed #'s of air/fuel)... And for the MAP and TPS problems, when's the last time you cleaned our your throttle body..?? Was your car idling erratically..??

jdm_xsi206

haha.. Well i think i might change the o2 sensor. Also my old motor never had a map sensor on it. My old map sensor was located somewhere else. But since my new z6 had a hole for a map sensor i jus used my old one. As for the tps i have no idea. Right now the car is ideling really low and goes up and down. And i can smell gass. My car feels really sluggish

nothing_shocking

I could be wrong, but aren't the map and the tps plugs the ones that are the exact same and can get mixed up? Not sure if you got the codes when you did the swap or if they came up while you were driving... Try switching the plugs for the two sensors. Like I said, I could be wrong about which two it is, but it's easy enough to be worth a shot.

JDM_SOHC

Naa they're different... The TPS has a retractable spring on the underside and the MAP has a hole for a vacuum line on the bottom... However I had a situation kinda like urs when swapping out a B7 and in a Z6... The car was a DX so the B7 MAP was mounted to the firewall and the Z6 was mounted to the Throttle Body... When I used the B7 MAP I had to reuse the B7 Throttle Body otherwise I was left with a hole on the Z6 Throttle Body... What I did was just found a Z6 Throttle Body, used the Z6 MAP and TPS sensors and than my idle was perfect...

This is for a B7, with a firewall mounted TB...


And this is a Z6, you can see the MAP mounted on the topside of the TB...

jdm_xsi206

well the thing is that i have three plugs that look the same. They all fit the map and tps. So i dont know which one to use for the new map sensor.

jdm_xsi206

does anyone know why i have three of the same plugs?

Former User

Post the wire colors in each plug.

Former User

Most HT members are actually very helpful.

jdm_xsi206

ill take some picture of them

jdm_xsi206

ok so the three different plugs that i have are the map sensor tps and one other one. I have listed the color of each plug

1. The first plug colors are yellow/green, green/black, i think it's white
2. The second plug colors are red/blue, yellow/white, green/white
3. The thirs plud colors are yellow/red, green/white, and white

if any one know's what each plugs to please let me know.

Former User

You may have two MAP sensor connectors. Only one is connected to the ECU.

jdm_xsi206

so which map sensor plug should i use?

Former User

For the MAP sensor hooked up to the ECU, the two outer wire terminals in the plug will have 5V with the key in ON(II) and the middle wire terminal will have 0V.

When you find the functional MAP sensor connector, plug it into the MAP sensor on the throttle body.

thanks alot for the help. On more question. My car also has a nasty gas smell. And also my car back fires a little. I was told to change the spark plugs. But i dont know if that will help.. I got the timing belt change. So i dont think its that. What could it be?

Former User

These problems may go away when the MAP sensor is properly connected and working.

jdm_xsi206

aight thanks alot for all the help
