Answers :

This P0506 code is one that's sometimes triggered on vehicles that have electronic throttle control. That is, they don't have a regular throttle cable from the accelerator pedal to the engine. They rely on sensors and electronics to control the throttle. In this case, the P0506 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is lower than the desired (pre-programmed) RPM.
\015\012Causes:
\015\012A P0506 DTC trouble code may be caused by one or more of the following:
\015\012· A vacuum leak
\015\012· An air restriction in the intake
\015\012·
\015\012· air path or exhaust
\015\012· A faulty positive crankcase ventilation (PCV) valve
\015\012· Damaged/failed/dirty throttle body
\015\012· Internal engine problem
\015\012· Failed PCM
\015\012
\015\012This DTC is more of an informational code, so if there are any other codes set, diagnose them first. If there are no other codes, inspect for vacuum leaks, restrictions, and damage. If there are no symptoms other than the DTC itself, just clear the code and see whether it returns
Idle speed too low

Hi, I have a 98 Honda Accord Ex V6 that showed the P0420 code and I was told that the catalytic converter needs to be replaced. So I replaced it and the check engine light came on with the P0401 code. I know the definition of the code and it gives me about 15 things that might be the problem... I'm planning on getting the passages cleaned and a new valve installed. What else should I do in order to get this fixed? My car doesn't show any symptoms of loss of power, knocking or anything like that.

Sounds more like an ignition misfire. Sometimes also, an exhaust leak in the pipe above the sensor can add enough air to cause the mixture in the pipe to ignite and cause the same problem. The first "weak point" in the exhaust is the muffler which is ... 1996 Jeep Grand Cherokee
