QuestionMy cirrus keeps dying. We read the engine codes with the start-stop trick and codes 11, 12, 32, and 43. We already replaced the EGR valve and vacume line off the intake maniford. Im just a little stuck on what to do next, it will run all day sometimes. Other days it will dye every block after only about 5 minutes. It still turns over but wont start.
AnswerHi Nick,
The code 11 hasn't been addressed yet, I guess? That one means that the spark timing signal from the crank sensor is not reaching the engine controller. These sensors are hall-effect solid state devices that begin to fail by becoming intermittent and then recovering after a cooling off period. The crank sensor is located on the trans bell housing just at the seam with the engine, under the distributor on the 2.5L engine which is the one I assume that you have. You will want to remove the cruise control servo from the driver's side strut tower. Then remove the retaining bolt on the sensor (the wire colors for the sensor are gray/black, black/light blue, and orange/white). Pull it straight up out of the transaxle housing. Then disconnect the plug. If the new sensor has a paper spacer on the tip, leave it there. Just install it until the tip touches 'bottom' against the flex plate surface. While holding it in that touching position, install and tighten the bolt to 105 inch-pounds of torque. Then reconnect the wires, and reinstall the servo.
That should solve the stalling. Just in case you might want to be sure that the egr valve is closed all the way when you try to start the stalled engine. Just inspect the slot on its stem to see that it is all the way down in the valve body. With a new valve that should not be the issue.
The 43 code is about a "miss" in the engine combustion but that is probably due to the crank sensor. While there are many other causes of missing, the way you describe the off again/on again phenomenon makes me suspect the crank sensor on your 2.5L engine, along with the code 11.
Replacing it should solve the problem.
