SOURCE: having trouble locating my idle air control valve

looking at the throttle body assembly, after removing the air filter housing, opposite side of the spark plugs, about an inch or two down, you should see a electrical connection, with four wires, the IAC has two small torxs screws that hold it to the throttle body.

My 2006 Trailblazer EXT LS gave a p0017 engine code. I replaced the camshaft sensor and it still has a rough idle and hesitates until you get up to 35mph. What should I do now?


Poo17 is for sensor b therefore you have a senor a on the cam as well and it maybe creating the problem. you need to check it as well. The code for cam senor a is poo16. If it runs rough when you start it you may have a bad idle air control or engine tem. control which tells the computer what the temp is outside and determines how much fuel is put into the engine. I would check the idle air control first.

Idle problem on a 2006 chevy trailblazer 4.2


The code indicates an issue with the Throttle Actuator control. This is a little motor on the throttle body that opens the throttle plates at idle. That control motor may be bad and thus, causing a low idle.

I hope this helps.
