Diagnostic Aids
A shorted or open solenoid, relay or bulb can cause a Code 26. If only one output circuit is bad, PCM will shut down only that circuit and not entire quad-driver. If any corresponding codes exist (i.e., Code 32, EGR), diagnose that quad-driver first.
NOTE:
The EGR Solenoid and Canister Purge Solenoid resistance values have been updated per Saturn TSB 96-T-08
