Hi.
I've been trying to track down why I am running rich and not boosting in my 1G-GZE RA23.
So, I disconnected each sensor in turn to see if it would throw an error code, in-between disconnecting the battery for 60 seconds to clear the ECU.......
First I did the green coolant temp sensor, and it threw what I thought was 22, but there was a long pause between each flash, so I think it is actually 11 - ECU power source. Back to this later......
Brown coolant plug - the cold start injector sensor, did not throw a code, as expected.
Throttle position sensor threw a 41, very nice thank you.
Idle Speed Control Valve did not throw a code.
Crank Angle Sensor did not throw a code.
Knock Sensor did not throw a code.
Oxygen Sensor again did not throw a code.
That's right, every one of these sensors had no effect on the engine light, it just kept flashing every 0.25 seconds continuously.
Thinking I had a code 11, I checked the battery voltage and got 12.25 static and then after 30 seconds after starting it was reading 13.78 / 13.80, so.....
Do I have my ECU earthing through the coolant temp sensor plug or is my wiring screwy somewhere else.....?????
All help appreciated - thanks !
Mitch.
