Hi Joe, I'm glad to help! The ambient temp sensor connects to the "Front Control Module" and when working properly will send the signal from the sensor to the overhead as well as other places that need an ambient signal. NOTE: Heres a simple way to see if the system is working properly. Unhook the connector at the Ambient Temp Sensor and the system should go to the default setting and the overhead display should read 40 degrees. If it does then the system is OK, replace the temp sensor. If it doesn't read 40 then various test must be performed to see if its the front control module or the overhead control unit. Hope this helps and have an awesome day Joe.

Replaced both knock sensors in 1999 silverado 5.3L. had computer re-programed for updated bulletin that was supposed to help engine knock and bring false knock codes from coming on. after a couple days,...

If the Knock sensor wire is located near the Ignition coil wiring the electro magnetic interference from the Ignition coil can rub off on the knock sensor wire causing the brain to think the knock sensor is sending a code.

You can place a millivolt meter across a knock sensor and tap it with a screwdriver and read voltage. If it doesn't read a voltage the sensor is bad. Its job is to generate a voltage.

Also, Using a timing light the distributor must be set to spec, if not this will trigger the knock sensor. Another trigger could be a bad temperature coolent sensor screwing with the fuel and timing, causing a knock. Some bad coolent temp sensors do not display a code when they're at fault, some simply slip under the radar. Usually when the temp sensor is bad the engine will not idle properly, or hesitates in most cases. The knock senser must have a good ground to the head or block, Do not use any thread tap or compound that would prevent a ground of the sensor.

Overtightened the coolent temperature sensor and it broke.

Take the piece that broke off to any auto parts store and they will have an extractor that will remove the other piece. good luck.
