control for canister close valve

10

Asked by May 11, 2014 at 10:35 AM about the 2008 Hyundai Santa Fe SE

Question type: Maintenance & Repair

I was getting a code 455 meaning gross leak in emissions, traced it down to the canister
close valve not closing. The valve works when jumper ed to 12 volts and ohm's out good at
20.6 ohms. There is 14 volts to the valve when its disconnected but as soon as I connect
the valve it goes to 0 volts. Where does the voltage drive for the valve come from?

It's controlled by the PCM (Powertrain Control Module). AKA the computer. My guess is either the valve is bad, your gas cap is bad, or you've got a leaking EVAP system vacuum hose. HTH. -Jim

Jim Thanks for your response but with the valve disconnected there is 14 volts to the connector for the close valve yet when I reconnect it it fail to pick the valve. Yet the close valve works fine when I jumper 12 volts to it and it Ohms out good. I can pull a good vacuum on the canister and gas tank. I think the problem is the drive to the close valve won't energize the valve.

You're welcome. Something else that occurred to me after I posted. Check for a good ground. Many times the PCM completes the circuit to ground to make a device work. HTH. -Jim
