I have an engine check light problem The KOEO AND THE KOER test gave me a 327 error code which according to the Haynes manual is the code for EGR VALVE PRESSURE TRANSDUCER/POSOTION SENSOR circuit below minimum voltage.
I found the efr valve control solenoid and theres battery voltage to it with key off.
I hooked a mightyvac to the ERG valve and couls it hear it moving. It also held a vacuume.
I understand there's a vacuum pressure sensor but I cant find it.
I'd like to take the EGR valve off if you thing its necessary but the bolts are almost inaccessable.
