My CEL recently came on and i pulled 3 codes:
0304 knock sensor
1003 Park/Neutral Position Switch
1005 EGRC Solenoid Valve

I have a '95 JWT ecu and the codes have come up before and i just reset the ecu and they were gone for a few months. also, i'm a 5spd convert, which may explain the park/neutral position switch, although i don't know why. my clutch has to be in for me to start the car.

what would you guys do first (i was thinking maybe try to figure out the EGRC solenoid valve and maybe the other codes will go away)? i'm just looking for advice on how i should approach this problem. any advice or suggestions would be helpful, thanks maxima.org.

Fix the items so that the codes will go away.

EGR will not make it all go away ...

 

Yes, start with the EGRC solenoid valve, that may be causing the KS code to appear as a ghost code. As you stated, your 5 speed conversion may be causing the Park/Neutral switch error.

 

thanks for your replies. has anybody changed the egrc solenoid valve?
if you could provide some helpful insight, i'd really appreciate it.
