ICP Sensor?

So what goes on inside that little bugger and how does it work? Out of curiosity I unplugged mine yesterday and the connector was covered in oil. So I remembered reading that if that happened it was time for a new one....

Does a HPOP gauge piggy back off that or something else?

Just a few questions I had....

HPOP gauge does "piggy back" on the ICP sensor.

If there is oil in the connector it should be replaced.

Here is a file that shows how the HPOP, IPR, and ICP work and some troubleshooting for the system. I have also heard that you use that location for a HPOP guage.

Hope this helps.
