The Oldsmobile Calais, also known as the Cutlass Calais, was produced by General Motors from 1985 to 1991. In 1987, the Quad 4 engine was developed and the 1988 Calais was fitted with it. All?æof the Quad 4 14 engine types of the 2.3 liter version are interchangeable on the 1988 Calais.
I would take it to a repair shop and have them check it out. If indeed the quad driver is defective you will have to replace the computor.
A DTC #26 is a Quad Driver Module Malfunction.
To set the timing on a 1990 Olds Calais with a 2.3L Quad 4 engine, first ensure the engine is at TDC (top dead center) for cylinder one on the compression stroke. Then, locate the timing mark on the crankshaft pulley and the timing tab on the engine. Use a timing light to check the timing; if adjustments are needed, loosen the distributor hold-down bolt and rotate the distributor until the timing light indicates the desired timing mark. Finally, retighten the distributor bolt and recheck the timing to ensure it remains in the correct position.
Quad drivers are small chips that perform on off functions inside the Engine Control Module. If you have a code which states there is a Quad Drivers Error, you need to check the items that that particular Quad Driver is controlling. For example, the a/c compressor relay, or trans solenoids etc...
P1655 refers to the Powertrain Control Module fault (quad driver 2)
You have to remove the intake manifold and be care full of the crank sensor
the quad driver module is a component of the ECM. you must replace ECM.
Look at your error codes again. It should read something like "quad driver module FAULT" not failure. It is VERY unlikely that your quad driver actually died. It is the high power control system that is in your computer. So replacing it, means replace the computer. To prevent this the Quad Driver has all sorts of internal protection hardware in its design. The likely thing that is wrong is something the Quad Driver is connected to. And that The quad driver isn't seeing every thing correctly so thus the Fault. It also can fault if there is a wiring problem from the device to the quad driver. There are Test for each component. You should to to find out which is the problem. Consult your Shop Manual.
