2005 Mitsu Endeavor p0506 Idle Air control.

2005 Mitsu Endeavor with p0506 Idle Air control stored. Veh is new to me w/84k miles. Any usual suspects for this code? Maintenance before me is unknown. One website suggested to do a full tune up to fix.

I'm a Toyota person, not familiar with Mitsu at all. Thanks.

Idle air control is not a sensor on the air horn.Why do people who have no clue bother answering? The idle speed is controled by the throttle body which allows a specific amount of air to flow into the engine thus controlling your idle speed. In this application it is an integral aspect of your throttle body. Check your throttle body for contamination. Check your wire harness connecters.

    Otherwise replace the throttle body.

DTC P0506

Circuit Description

The throttle actuator control (TAC) motor is controlled by the powertrain control module (PCM). The DC motor located in the throttle body drives the throttle plate. In order to decrease idle speed, the PCM commands the throttle closed reducing air flow into the engine and the idle speed decreases. In order to increase idle speed, the PCM commands the throttle plate open allowing more air to pass the throttle plate. If the actual idle RPM does not match the desired idle RPM within a calibrated time, this DTC sets.

This diagnostic procedure supports the following DTC:
DTC P0506 Idle Speed Low

I replaced the alternator belt and battery. Now it is idleing different. It shows code P0506. I have checked the hoses and connections and I cannot find anything bad. What should I try next?


Hi:
Here is info on your code:

P0506 - Idle Air Control (IAC) System RPM Lower Than Expected

What does that mean?
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.

Potential Symptoms: Most likely the only thing you'll notice is the idle speed is lower than normal so it will likely be rougher. There are potentially other symptoms as well. Of course, when trouble codes are set, the MIL (malfunction indicator lamp, a.k.a. the check engine light) illuminates.

Causes: A P0506 DTC trouble code may be caused by one or more of the following:
* A vacuum leak
* An air restriction in the intake air path or exhuast
* A faulty positive crankcase ventilation (PCV) valve
* Damaged/failed/dirty throttle body
* Internal engine problem
* Failed PCM


The first thing to do is clear the code and see if it comes back, and if it does, work your way thru the list of possible causes.

unfortunately no ! Your best bet take it to the dealer . The P0420 always ends up being the catalytic converter ! P2104 isn't throttle air control . P2112 - Throttle Actuator Control (TAC) System - Stuck Closed. Description: This powertrain control module (PCM) fault status indicates the throttle plate is at a lower angle than commanded. Possible Causes:
  • Binding throttle body, stuck closed.
  • Damaged PCM.
Diagnostic Aids: Application Key On Engine Off Key On Engine Running Continuous Memory All GO to DV1
P2104 - Throttle Actuator Control (TAC) System - Forced Idle Description: The TAC system is in the failure mode effects management (FMEM) mode of forced idle. Possible Causes:
  • Open or short in multiple accelerator pedal position (APP) sensor circuits.
  • Damaged APP sensor.
  • Damaged powertrain control module (PCM).
Diagnostic Aids: This DTC is an informational DTC and can be set in combination with a number of other DTCs which are causing the FMEM. Diagnose other DTCs first. Application Key On Engine Off Key On Engine Running Continuous Memory All GO to QE1
P0506 - Idle Air Control (IAC) System RPM Lower Than Expected For Vehicles With Electronic Throttle Control (ETC) Description: This DTC is set when the powertrain control module (PCM) detects an engine idle speed that is less than the desired RPM. Possible Causes:
  • Air intake restriction.
  • Exhaust restriction.
  • Engine mechanical fault.
  • Damaged electronic throttle body (ETB).
  • Damaged PCM.
Diagnostic Aids: This DTC is informational only and it may be accompanied by other DTCs. Diagnose other DTCs first. If other DTCs are not present inspect the intake air system for air restrictions and damage. If no concerns are present, clear the DTC and retest. For All Others Description: This DTC is set when the powertrain control module (PCM) detects an engine idle speed that is less than the desired RPM. Possible Causes:
  • IAC circuit open.
  • Air inlet is plugged.
  • B+ or VPWR to IAC solenoid open.
  • Damaged or incorrect IAC valve.
  • IAC valve stuck closed.
  • VPWR to IAC solenoid open.
  • IAC circuit shorted to PWR.
Diagnostic Aids: Disconnect the IAC valve and look for little or no change in engine RPM as an indication of a stuck or damaged valve. Application Key On Engine Off Key On Engine Running Continuous Memory Vehicles With Electronic Throttle Control (ETC) Refer to the Description, Possible Causes and Diagnostic Aids for the DTC. All others GO to KE1

* A faulty positive crankcase ventilation (PCV) valve
* Damaged/failed/dirty throttle body
* Internal engine problem
* Failed PCM

Possible Solutions: This 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.

Hope helps.
