Alfa 147 lambda values -motor control failure. Some help please!
Well, i got the motor control system error warning appear about a month ago.
I have fiatscan and the right cable. I cleared the errors, without really jknowing what i was doing in fiatscan, i am sure they will come back though. so i can post them up here. The errors related to the fuel mixture.
From my limited knowledge I thought it must be the lambda sensor! I have now learned that there is two! Proving a modern injection/ecu system is abit more complicated than my single injector classic mini!
However i do have the live data, which hopefully someone can interpret:
Lambda 1 signal (pre-cat) - 0.440
Lambda signal 2 (pre -cat) - 0.445
Lambda 1 signal (after cat) - 0.460
Lambda signal 2 (after cat) - v (which i assume is no signal)
Lambda 1 status (pre-cat) -closed loop - all at full operating temp circa 90 degrees
Lambda 1 status (after-cat) - open loop
Lambda 2 Status (pre -cat) - closed loop
Lambda 2 Status (after -cat) - Open loop
when turned to the MAR position all status were closed, if that makes a difference!
All input appreciated, i would like to try and fix this myself, without a garage!
