    Write a function that analyzes a vehicle's diagnostic code to verify if the maintenance system is operating within normal parameters. The function should check if each sensor threshold value (represented by a digit in the diagnostic code) appears no more times than its own value in the code. For example, in a diagnostic code 22314, the digit 2 can appear up to 2 times, 3 up to 3 times, and so on.
