Frequently Asked
Will code P0741 clear itself?
OBD-II codes do not clear themselves. The underlying fault must be repaired and the monitor must pass during a drive cycle before the light extinguishes.
Can I pass an Arizona emissions test with P0741 active?
No. Any active check engine light is an automatic emissions test failure in Arizona. The code must be resolved and the relevant monitor must complete before testing.
How long does a diagnostic take?
Most diagnostic appointments at Apex take 45–90 minutes. Complex electrical faults may require additional time for circuit testing.
