I have been working on a 1993 Saturn LS 1.9 DOHC, and it has a DTC of 26, QDM Failure.

I have been working on a 1993 Saturn LS 1.9 DOHC, and it has a DTC of 26, QDM Failure. So far we've replaced the coolant temp sensor, due to the fact that it seemed to be a little loose (the plastic was about ready to break off). And I checked for vacuum leaks, ensured the EGR valve wasn’t stuck, and replaced the map sensor. Any other suggestions or could you shed some light on the QDM and what it does exactly? Quad Driver Output Fault
