I have a split/splitless EPC module from a 6890 with a bad pressure transducer. It reads 152psi with any pressure at all and zeroes to 1.5 psi - it doesn't read anything in between. I called Agilent and they don't sell the individual parts but the guy I spoke with said he used to replace parts on EPC's. He looked for the parts breakdown for one and couldn't find that. Does anyone know if parts are available for these? Is there a parts diagram available anywhere?

Check this web site and contact John Kroska. He gives us great service on out 5890s and I know he does service on 6890s also.

Try taking it apart and look for blockage of any of the ports. We had a problem with a liquid possibly water in ours. Sonnicated parts in MeOH and that took care of it. Also, can check the solenoids with an ohm meter. Ours read 130 ohms.
