How do I reset my mitsubishi idle air control valve?
How do I reset my Mitsubishi idle air control valve?
- Depress the accelerator pedal slightly.
- Start the engine and run for 5 seconds.
- Turn the ignition switch to the OFF position for 10 seconds.
- Restart the engine and check for proper idle operation.
When does the p0506 code set on a car?
The P0506 code is sets when the Powertrain Control Module (PCM) detects an engine speed outside of the Idle Air Control (IAC) range of control.
How does the throttle position sensor ( TPS ) and idle air control valve work?
This Video explains how the Throttle Position Sensor also known as TPS and the Idle Air Control Valve ( IAC ) Work. On the previous 2 Videos I explained how the Fuel is delivered to the Fuel Injectors by the Fuel Pump, I also explained the parts involved to make that happen.
How does the Powertrain Control Module ( PCM ) work?
The Powertrain Control Module (PCM) learns the idle position of the throttle plate to ensure the correct idle. Anytime the throttle body is cleaned or replaced, the PCM must learn the new throttle position. The idle may be unstable or a DTC may set if the throttle position is not learned.
How does the PCM reduce the idle speed?
The PCM commands the Idle Air Control 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.
When is the p0506 DTC code triggered?
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. 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.
When is the p0506 idle air control system lower than expected?
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.
What does the code p0506 mean on an air conditioner?
The error code P0506 can be defined as the “Idle Air Control System RPM Lower than Expected”. Meaning, the RPM or revolution per minute of an inactive control system is below the standard. This issue is often the result of the damaged idle air control engine & vacuum leaks, leading to power loss and decreased engine performance.
How to check for a dirty throttle body?
Damaged/failed/dirty throttle body 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.
