Cadillac Repair/reset engine light for 2006 ford taurus se


How to reset the engine light after I replaced air flow according to the code given from auto zone guys who used the tools when they hook it up to the car.


I find it interesting that Autozone had the equipment to diagnose a problem and yet not to reset the system. The only way you are gong to reset this system is with a Ford NGS (New Generation Star) electronic diagnostic scanner or equivalent.

You do not even want to unhook the battery because you will lose your key codes and the engine will no longer start until an NGS or equivalent is used to reprogram the keys.

These computer systems are not owner friendly. They are designed to go to the dealer or a service center with the proper equipment.

Its so common for people to thing they can reset an engine light like that of rebooting a computer. Unfortunately in most cases the owner cannot turn these lights off by a simple reset.

The problem with Autozone is that most people there are not technicans and they are merely parts changers. I have seen my share of incorrect diagnoses from these parts store. I am not saying that is so in your case and you will find out when a scanner is put on the car.

Good luck!

Alarm system questions cannot be answered on this forum. These systems are not what I can answer. Without being physically at the vehicle and not knowing what kind of electrical service has been done on the vehicle, there is no possible way to give an accurate answer over the internet. My expertise is in Ignition/key based anti-theft systems. These issues include GM VATS (resistor chip in key blade) PASSLOCK (MRD)-ignition lock rotation based, no special ignition key and the PKIII Transponder (computer chip in key) systems. These systems are not alarm based and are integral with the starting of the engine. This is why I cannot diagnose alarm problems without physically looking at the vehicle: Alarm systems are a completely different annimal than ignition key/lock based anti-theft system. Many alarm questions come from vehicles 10 years old, and since older, many hands that had been involved over the years.I am an expert in all GM factory (ignition/key based)systems. Alarm system questions pose to many situations beyond my knowledge as to what has been done to the vehicle over the years. Some guy may have actually wired the stereo into the alarm system. Who knows? Over my past 30 years in vehicle wiring repair, I have seen unbelievable wiring disaters done by guys that consider themselves "mechanics." I have seen stereos and alarms intalled using surgical tape. I have seen modules burn up, un-fused circuits, wiring jambed between the doors and even lamp cord used for a starter kill. To answer alarm questions over the internet without examining the vehicle is like asking; What does it take to remove a dent?
