DTC Code #327
 

I have a 1993 2.3L Ford Ranger XLT.

When I turn on my ignition, the RPM's accelerate up to 3000-4000 without having to press on the accelerator. They remain at that RPM during the idle.

I have run the KOEO check light test and the following code was retrieved:

#327 - EGR valve position circuit below minimum voltage

Where should I now concentrate my attention?

I have cleaned the MAF sensor with electrical cleaner and that has not corrected the problem.

I am now looking at replacing the EGR Vacuum Regulator (EVR) Solenoid. Anyone else have this problem before?

A code 327 usually means a bad DPFE sensor.
