Ive got a problem with my ISCV not working . Cleaned it up and tried it on the battery and it works fine , try it on the car and it doesnt . Ive got 13v+ on one side of the connector and 5v+ on the otherside and 4v between the pins . Ive got a new wiring loom in too only 6 months old from Ryan so i cant see that being a problem . All the sensors are about 6 months old too . Is there anything i can check or does it sound like a problem with the ecu ? If its the ecu who repairs them . Am i also right in that its a switched negative so why the 5v+ on the other pin . Strange , any help is much appreciated .

Cheers Travis .

 

sounds like a short on the wiring if its getting a live to a pin that should be earth, im no sparky tho

 

Correct permanent live, earth is switched by ECU, digi meter will not be able to measure the voltage as the pulsing will be to fast for it, you really need a oscilloscope or a NOID light. As to why both sides are live I am confused is it standard L1/6/8 ECU, that is why it won't work as you have 2 lives.

Its on an L8 ecu , everything else works fine just the ISCV .

It is strange how its getting two feeds , does anybody know which are the ecu pin numbers so i can see inside the ecu and check that .

 

For wiring diagram see: http://www.bigturbo.co.uk/main6.htm

 

Thanks Oldford i will check it now .

 

Ive checked it and pin 34 is giving out 5v when it should be 0v so it is deffo a ecu problem .

Does anyone know who repairs them or should i just get a second hand one ?
