ECU pinout

[morgie]

Does anybody has the Shop manual for our legacy 92 turbo ?

I Need one little info, On page 6-24 and 6-25, there is the "Bypass air control solenoid" ... the wires goes op to the top of the page, and goes into the Ecu, but on the page 25, wich i dont have !!!! :\

can you tell be what are the pins in wich the Solenoid connects ? (ex : a3, b4, c9...etc) and the color code for those wires.

thanx, that would save me a lot of time !

Morgie,

I got the manuals....but I'm not sure I have the same page setup you do......if you can give me a section heading, I can find it.

[morgie]

Section 6 - 3 Wiring diagram and troubleshooting
MPFI - Turbo
fig. 29-2.

in the page, you have the pins for :

Water Temp Sensor, throttle sensor, Bypass Air Control solenoid valve, cam angle sensor, crank angle sensor, knock sensor.

In fact, what i need is the Pins on the Ecu, and the wire-color for the "Bypass Air Control solenoid valve" , or Wastegate Solenoid, or wathever else it may be named

thanx !

Well.....the bypass air control solenoid valve......commonly refered to as the idle air control valve.

The pins on the ECU are 1 & 2 on connector F47. F47 is the longest one, and pins 1 & 2 are on the inside on the top......with connector F47 on the left. Colors should be black & white.

humm, so i might not be looking at the right thing !

i'm looking for the Wastegate Solenoid. :\

The wastegate solenoid is actually pin 3 on the same connector Josh explained that the IAC valve is on. Find the 2 IAC valve wires; the next one is the wastegate control solenoid.

[morgie]

the wastegate solenoid is the one that gave me such a hard time today... and still not solved :\

I get an ecu error code 45 and 44, so anytime i get a boost over 0.01, paf, fuel-cut.

err
will have to pause investigation till monday, and put jumpers over Boost Wire and MAF wire so i can use the car normally till monday

[morgie]

Now that i've replugued everything like it was originaly, i get a 35 error code..

35 Canister purge solenoid valve Solenoid valve inoperative none X X

What's a "Canister Purge Solenoid Valve" ??? where is it located ???

thanx !

C'mon now Morgie, we've been over that stupid valve thousands of times now

Just kidding, do a search for CPV or purge valve, and I'm sure you will come up with some helpful tips!
