P1506 Idle Air Control Overspeed Error
The Idle Air Control (IAC) valve adjusts the engine idle speed. The valve is located on the side of the throttle body. The valve is controlled by a duty cycle signal from the PCM and allows air to bypass the throttle plate in order to maintain the proper idle speed.
Due to the diode in the solenoid, place the ohmmeter positive lead on the emphasis type="medium" VPWR/emphasis terminal and the negative lead on the emphasis type="medium" ISC/emphasis terminal.

A P0303 code means that the the car's computer has detected
that one of the engine's cylinders is not firing properly. In this
Symptoms may include:
A code P0303 may mean that one or more of the following has happened:
If there are no symptoms, the simplest thing to do is to reset the code and see if it comes back.
If there are symptoms such as the engine is stumbling or hesitating, check all wiring and connectors that lead to the cylinders (i.e. spark plugs).
Depending on how long the ignition components have been in the car, it may be a good idea to replace them as part of your regular maintenance schedule. I would suggest spark plugs, spark plug wires, distributor cap, and rotor (if applicable). Otherwise, check the coils (a.k.a. coil packs). In some cases, the catalytic converter has gone bad. If you smell rotten eggs in the exhaust, your cat converter needs to be replaced.

Hello! The Idle Air Control (IAC) is setting P1506...Idle is to high...Other problems can cause the idle to over speed...It isn't the IAC in many instances...A vacuum leak is #1...The vehicle has some years on it...Go over the vacuum lines and look for weak collapsed lines, broken, or poorly seated...A defective PCV valve is #2...If it hasn't been changed in awhile it's due...Base idle should be 780 in neutral...If # 1 and #2 prove to be OK I'll take it from there...
