Question
Wut lights would the idle air sensor or tps sensor make come on my dash

Answer
Hello,

The service engine soon, check engine, or service engine now. all are amber and tell you there is an emissions issue, computer or sensors. To know exactly the diagnostic code a scanner such a Tech II must be used and many service centers have them. Whatever you do, DO NOT go to the dealer, notorious for not repairing anything and charging you for parts and replacement of perfectly good components!

I would tell you not to go to parts stores like Auto zone that do have the equipment, however, just because the code reader will tell you the sensor circuit involved (maybe unless after affect for a cascading issue caused by another sensor).

These types of issues usually require a professional. Possibly it is not the sensor ad in the wiring, which is physically checked. I can't tell you as to how many hundreds of people over the years that have changed components they thought werre bad, and that was not the problem.

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?
