Hello All,

I have a 95 mustang that I just pulled codes on. The only code that came up was 327 - DPFE or EVP circuit below minimum voltage of 0.2 volts. I tested the wires going to the EGR valve position sensor and noticed there was .05 volts going to it at rest (VREF and SIGRTN). With the ignition turned on the voltage sat at .56 (EGR signal wire and SIGRTN). I read that those readings are normal. I also wiggled the connector to see if there was a loose connection. The voltage stayed steady. The vacuum lines seem to be ok. I havent detected any leaks. I disconnected them and blew threw them one by one and none of them leaked. I have replaced the EGR valve and EGR valve position sensor within the past year and a half. It was from Kragen but I dont remember what brand. Anybody have any suggestions or guidance on this issue?
