What can cause P0507?
What Is the Cause of Code P0507?
- Faulty Idle Air Controller (IAC) Valve.
- Intake/vacuum air leak (most likely cause)
- Faulty power steering pressure switch.
- Faulty electric throttle control actuator.
- Improperly adjusted throttle cable.
- Carbon buildup on the throttle body.
How do you fix the idle air control system RPM higher than expected?
Check the PCV valve as well and see if it is blocked and needs a new replacement. Inspect the IAC (Idle Air Controller) if it is equipped, and verify its performance. Try swapping in a new throttle body (if available) and see if it can fix the problem.
What is code P0505?
engine idle control system
P0505 is an OBD-II generic code that the engine control module (ECM) determined the engine idle control system is not managing the idle to stay in specification. The idle is too high or goes too low.
How do you relearn idle?
A. Idle Relearn
- Start the engine in Park/Neutral. Rev the engine to above 2,500rpm and hold for 10-15 seconds.
- Slowly reduce throttle back to idle.
- The ECU should now begin to learn the idle position (you will hear the sucking sound through the throttle body change as the Idle Air Control Motor changes position).
What code is P0174?
What the P0174 code means. Code P0174 indicates that there is a lean condition detected by the Engine Control Module (ECM). A lean condition will be created if there is too much air, and not enough fuel, in the air fuel ratio (AFR).
What are the symptoms of a bad air idle control valve?
Usually, a bad or failing idle air control valve (IAC); will produce a few symptoms, that can alert the driver of a potential issue:
- Irregular Idle Speed.
- Check Engine Light Illuminated.
- Rough Engine Idle.
- Engine Stalling.
- Stalling Under Load.
- How To test the coil driver circuits in the (IAC) valve:
How do I fix code P0505?
What repairs can fix the P0505 code?
- Replacing the IAC valve and cleaning the throttle body and passages.
- Removing carbon from throttle body and IAC passages and clean IAC.
- Repairing a vacuum leak in the engine intake manifold vacuum system or gaskets.
Can I drive with a P0505 code?
Trouble code P0505 should be diagnosed and repaired as soon as possible. Not recommended, however, you may drive your vehicle while trouble code P0505 is present unless the engine stall or stumbling is is severe enough to hinder proper vehicle operation. Erratic or lack of idle control may be noticed.
How is P0505 diagnosed?
What are the symptoms of the P0505 code?
- The Check Engine Light will be illuminated and the code is set in ECM memory.
- The engine idle may be lower or higher than specifications.
- The engine may idle rough if it has a vacuum leak.
- The engine may stall when coming to a stop.
- The engine may idle too high at times.
What does the p0507 code stand for?
A P0507 code is a generic powertrain code that stands for “‘Idle Control System RPM Higher than Expected.”
When does p0507 idle air control system higher than expected?
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 P0507 DTC (diagnostic trouble code) is triggered when the PCM (powertrain control module) detects an engine idle speed that is greater than the desired (pre-programmed) RPM.
What does the OBD code p0509 mean?
This OBD-II code belongs to a series of fault codes (P0505 to P0509) that pertain to a fault in the idle control system, and it means that the engine computer has detected that the engine idle speed has exceeded the manufacturer’s pre-programmed specifications for a certain amount of time.
