Where is the crankshaft sensor on 2007 trailblazer 4.2 engine
Below are a couple of pictures that should help. The connector is only 2 terminals with I believe a purple and yellow wire going to it. Don't forget to put a little oil on the O-ring when installing it. Not sure if you are aware of this but if you are replacing it you will need to do what's called a crankshaft position (CKP) sensor variation learn procedure. This "teaches" the senor or "adapts" the new sensor to your vehicle so your vehicles computer (PCM) will know how to use it correctly. In most cases if this isn't done the computer will overide how that sensor is used in order for the vehicle to run. Also in most cases if this isn't done a diagnostic trouble code (DTC) of P0315 will pop up and your check engine light will come on. You will need special diagnostic equipment in order to perform this procedure. I hope this helps....

Where is the throttle position sensor is located in a 2007 chevy malibu
I believe, if it's a 2.2 ltr the sensor is built into the throttle body unit and you'll have to replace the whole Throttle body which cost about $300-$500 to do yourself depending on where you purchase it from. Before replacing, check the wires for cracking or rubbing causing any shorts

There are some testing procedures that should be done to fully diagnose the diagnostic trouble code (DTC) of P0327. The part you can probably get after market for around 40 to 50 dollars. If you want tp take the chance and go ahead and purchase one you can try. Most likely that's the problem but there may be an open circuit. That would be up to you though. You have 2 knock sensors in your vehicle. The DTC of P0327 happens to be the easy one of the 2. Below is a picture of the location of the one your DTC is refering to. Hope this helps....
