code 335

[jaykelp]

I am getting a code of 335. I believe I am reading my voltmeter correct. I have a 95 ex sport. I have replaced the egr valve, the sensor and the IAC. Any suggestions?? Some of my friends have mentiioned that may be the Cat conveter. The CEL is on of course.

so you replace your egr and your pressure feedback sensor? if so you might want to replace your vacuum seleniod that lets vacuum get to the egr, because if the computer commands the egr to open and it dont, the pressure feedback sensor will pick that up and set off 335. you can also let your vehicle warm to operating temperature, disonnect the vacuum hose to the egr and hook it a vacuum gauge, rev to around 2k it should show around 5 to 8 pounds off vacuum. if your not getting a reading check the vacuum before it goes into the vacuum seleniod, if your getting a reading now then replace the vacuum seleniod.
