English meaning: Not at present.

P0506 fault code knowledge:

no

Cause and effect of failure: p0506: Possible cause of low idle speed 0 1 failure 01-0/ignition system failure. 0 1-02 air leakage fault of air intake system. 0 1-03 low cylinder pressure fault. 0 1-04 throttle failure. 0 1-05 fuel system 0 1-06 engine control unit failure. P0507: Idle speed is too high 0 1 possible failure cause 01-0/ignition system failure. 0 1-02 air leakage fault of air intake system. 0 1-03 low cylinder pressure fault. 0 1-04 throttle failure. 0 1-05 fuel system 0 1-06 engine control unit failure.

Suggested solution: 0 1dtc detection step: Make sure the battery voltage is normal before performing the following steps. 0 1-0 1 Turn off the start-stop button and all electrical appliances. 0 1-02 Connect the diagnostic instrument bds to the vehicle diagnostic interface. 0 1-03 Start-stop button is placed in "Run" mode. 0 1-04 read and clear the DTC with diagnostic tools. Tip: Use the latest software for testing. 0 1-05, turn off the start-stop button and all electrical appliances, and put the start-stop button in the "run" mode again after 3-5 seconds. 0 1-06 (restart the engine for road test, so that the engine can run under various working conditions. ) 0 1-07 read DTC with diagnostic instrument. 0 1-08 If DTC is detected, there is something wrong with the vehicle. Please perform the corresponding diagnostic steps. If no DTC is detected, the previously detected fault is an accidental fault. 02 Diagnostic Steps: Tip: After troubleshooting, reconfirm whether the DTC and symptoms exist. 02-0 1 Check whether the generator is normal. be
