SES Code 26, replaced PCV Valve....
Hello all, I am getting a Code 26 so I replaced the PCV Valve and the light is still on. It does not come on immediately, usually a min or so after startup. Do I need to reset the computer to clear the code, or is there still in fact still something wrong? The car runs and drives fine, any thoughts?

DTC 26 on a 1993 is (courtesy of Shoebox):
Quad-Driver Module (QDM) #1 circuit applies to:
- AIR pump relay circuit
- EGR solenoid
- EVAP solenoid"
The code has nothing to do with the PCV valve. In fact there are no codes at all related to the PCV valve.
One of the devices listed above has an electrical fault. I'll say its probably a blow fuse for the AIR pump. If that's not it, check the EGR and EVAP solenoids. If all those are OK, it could be a faulty quad driver module, a component in the ECM case.

Ok, I checked the fuse, it was fine. I then checked the air pump relay and it is working fine as well. Does anyone know exactly where the EGR and EVAP solenoids are?
