You will need to replace the IAC (idle speed control airbypass valve) it is near the ythrottle valve in the intake, it has either a black or gray connector going to it, don't confuse it with the throttle position sensor.

SOURCE: Engine code P0505 for 2002 honda odyssey

p0505 is directly related to the idle air control valve (sometimes called the rotary valve) i cant count how many of these i have replaced on hondas. It is located directly under the throttle body so it can be difficult to replace. I would recommend you having a professional replace this due to the difficulty of the valve removal

SOURCE: check engine light fault code PO505

This code is for your electronic throttle control system it probably needs to be cleaned the butter fly sticks due to build up in side the throttle body clean with tooth brush and emission save throttle body cleaner clear codes and then dissconnect the battery for 3 hours hook back up then go for a short drive stop and go to reset idle control that should take care of this.

When engine gets hot, idle is up and down with the engine light on. OBD code gives a P0505 code.


per this address "http://www.obd-codes.com/trouble_codes/" p0505 is a "IAC (Idle Air Control) System Malfunction" it gives some good suggestions to look at to find a solution for your problem.

2001 Toyota Sequoia is showing a P0505 and PO420 error code; how do you correct these issues.


P0505 Idle Control System Malfunction

IACV or Idle Air Control Valve if equipped is malfunctioning.

P0420 Catalyst System Efficiency Below Threshold (Bank #1)
The Catalytic converter is not working up to par in Bank#1.

I think this will point you in the right direction..

I have a 2004 Toyota Corolla and my check engine light is on. The code is P0505: Idle system malfunction. I have replaced the Idle Air Control Sensor and PVC (?) Valve and have no clue what else it could...


P0505 is correct, but replacing the IAC won't help if the PCM cannot control and/or monitor the operation

you need to measure voltage at the IAC and/or the signal return to the PCM
