P0507 Chevrolet Description

The Idle Air Control (IAC) valve is a Powertrain Control Module (PCM) controlled stepper motor located on the throttle body. The stepper motor drives a valve pintle which protrudes into a passage that bypasses the throttle plates. The PCM commands the IAC valve pintle to extend to decrease the idle speed. The bypass air flow is reduced and the idle speed decreases as the pintle approaches its seat. The PCM retracts the IAC valve pintle away from its seat to increase the idle speed. The retracting of the IAC valve pintle allows more air to bypass the throttle plates. One of the PCMs uses for the IAC system is to maintain a desired idle speed. This DTC sets when the PCM detects an engine speed outside of the IAC\'s range of control.

Stop at an "autozone, Pep boys, or other autoparts store and they will usually scan it for codes and direct you to area of problem for free. If they are not sure, get back to us with problem code.

There is a Dodge website (not from the corporation, but from fans) for Dodge vehicles and they have a subsection on the Caliber. There is a 2007 or a 2008 service manual online there if you join their group. good luck.

disconnect the battery for 10 minutes and try to reset the codes.

Not a common code. please read.
See the dealer on this, it is a warranty issue.

could that be P0008? I'm not showing the code you've listed, but if you reply to this feed I will help you out If it is the code I listed, then its this , P0008 Engine Position System Performance (Bank 1) This error basically means the engine is out of Sync.The Camshaft and Crankshaft are out of position or at the very least think they are. Engine timing may be out and thus your engine is in danger of complete destruction. At the very least a camshaft sensor maybe down. Take the vehicle to a mechanic so they can check the timing issues

p2173 High air flow vacuum leak detected (Slow accumulation) Most likely problem is a vacuum leak. This is related to the electronic throttle control. Ck around plastic intake
