Code P1507 Mitsubishi Description
The P1507 diagnostic trouble code (DTC) for Mitsubishi vehicles indicates that the Idle Control System RPM is higher than expected at low temperatures. This code is typically triggered when the engine's idle speed is higher than the predetermined value set by the manufacturer when the vehicle is operating in cold conditions. The Idle Control System is responsible for maintaining the engine's idle speed within a specific range to ensure smooth operation, fuel efficiency, and overall performance.
Common Causes of P1507 Mitsubishi
- Malfunctioning idle air control valve
- Vacuum leaks in the intake system
- Dirty or faulty throttle body
- Malfunctioning coolant temperature sensor
- Issues with the engine's computer system
Symptoms of P1507 Mitsubishi
- Rough idling or fluctuating idle speed
- Engine stalling or surging
- Decreased fuel efficiency
- Engine hesitation or lack of response to throttle input
- Check Engine Light illuminated on the dashboard
How to Fix P1507 Mitsubishi
- Diagnose the root cause of the issue using a scan tool to retrieve the trouble codes and perform a thorough inspection of the idle control system components.
- Clean or replace the idle air control valve to ensure proper operation.
- Inspect and repair any vacuum leaks in the intake system.
- Clean the throttle body to remove any carbon buildup or debris that may be affecting its function.
- Test the coolant temperature sensor and replace it if necessary to ensure accurate temperature readings.

2. What are the common symptoms of a P1507 code in a Mitsubishi?
Symptoms include a high idle speed, rough idle, increased fuel consumption, and potentially the check engine light illuminating.
3. What causes the P1507 code in a Mitsubishi vehicle?
Common causes include a malfunctioning idle air control (IAC) valve, vacuum leaks, dirty throttle body, or issues with the engine coolant temperature sensor.
4. Can a vacuum leak trigger the P1507 code?
Yes, a vacuum leak can cause unregulated air intake, leading to a higher-than-expected idle RPM and triggering the P1507 code.
5. How can I fix the P1507 code on my Mitsubishi?
Repairs may include cleaning or replacing the idle air control valve, fixing vacuum leaks, cleaning the throttle body, or addressing any faulty sensors.
6. Is the P1507 code serious?

7. How do I diagnose the P1507 code on a Mitsubishi?
Diagnosis involves scanning for additional codes, inspecting the IAC valve, checking for vacuum leaks, and testing the throttle body and related sensors.
8. Can a dirty throttle body cause the P1507 code?
Yes, a dirty or clogged throttle body can restrict airflow, leading to an imbalance in the idle control system and triggering the code.
9. Is the engine coolant temperature sensor related to the P1507 code?
Yes, a faulty engine coolant temperature sensor can give incorrect temperature readings, affecting idle speed and causing the code.
10. Can I drive with the P1507 code on my Mitsubishi?
You can drive the vehicle, but it’s recommended to address the issue promptly to avoid further problems with idle control or engine performance.
