IDLE SPEED REGULATIONFiche n° 27
XR25 aid:Engine speed , Minimum < # 06 < Maximum
No fault bargraphs should be illuminated.NOTES
# 06 < MinimumThe idle speed is too lowNOTES
Idle speed regulation is not maintaining the idle speed.
- Clean the air supply circuit (throttle body, idle regulation valve), since it is probably contaminated.
- Check the engine oil level (too high ---
> splashing).
- Check and ensure correct fuel pressure.
- Using the OPTIMA 5800 station, check the engine compression.
- Check the valve clearances and the timing.
If all these points are correct, replace the idle regulation motor.
# 06 > MaximumThe idle speed is too highNOTES
An air leak may be affecting the idle speed regulation programming.
- Check the connections on the manifold.
- Check the hygiene of the pipes on the manifold.
- Check the pneumatically controlled solenoid valves.
- Check the manifold gaskets.
- Check the throttle body gaskets.
- Check the sealing of the brake servo.
- Check the restrictions are present in the oil vapour rebreathing circuit.
- Check the fuel pressure.
If all these points are correct, replace the idle speed regulation motor.
