DTC P0507

DTC: P0507 Idle control system rpm higher than expected

Activation requirement CHECK ENGINE lamp:
Two consecutive trips with failure.

Activation of CHECK ENGINE lamp:
At start of next trip.

Test to detect fault:
With the vehicle stationary, A/C compressor turned off and engine at operating temperature, the idle speed control checks if the regulating value at the idle speed control actuator has reached its lower limit and if the engine speed is still too high. This is transmitted via CAN to the diagnostic module.

If the regulating value remains at the lower limit for a specified time and the engine speed deviation is greater than approximately 150 rpm, the diagnostic module recognizes a fault.
