1996 Toyota Corolla P0401 Codes

[danielsaun2003]

I am stumped, I have replaced the EGR valve, the vacum modulator and still get a check engine light on, any thoughts or suggestions? I keep getting code P0401.

I had the guy at Checker Auto Parts test the VSV and it read 1 ohm only, when Haynes manual says between 37-44 Ohms in normal. Could that be possibly that low? We both looked at each other not sure. He even got a new meter and it read the same. I don't know maybe he didn't know what was up?

Oh yeah, first I replaced the O2 sensor on the front as the first diagnostic said Front Left Bank O2 sensor, now like I mentioned I keep getting code P0401. The O2 sensor code seems to have been resolved.

Any help would be appreciated. In parts alone I am over $300 in the hole and probably could take some back as they look new if not needed? The car runs good with the check engine light on, but it will be difficult to sell a year from now unless fixed. Thanks for your help.
