Can You Pass Inspection with Check Engine Light On in NJ?: Understanding Your Options for Vehicle Inspections

If your check engine light is on, it’s crucial to grasp how it impacts your vehicle's inspection status in New Jersey. Typically, a vehicle will not pass inspection if the check engine light is illuminated. This warning signifies that the vehicle’s onboard diagnostics system has identified an issue, potentially affecting emissions or safety.

The inspection procedure in New Jersey encompasses an exhaustive review of your vehicle's emissions system. When the check engine light is lit, it signals that attention is required, which may involve necessary repairs before your vehicle qualifies for a successful inspection.

Nonetheless, there are several scenarios where you could still pass inspection even with the light aglow:

1. Previous Repairs and Resets

If you’ve recently completed repairs and the check engine light remains illuminated, it could be due to the need for a system reset. In such cases, visiting a mechanic for a reset prior to inspection is advisable. Always ensure that all issues have been addressed before making another inspection attempt.

2. Reputable Diagnostics Check

Before visiting the inspection site, it’s wise to obtain a diagnostic check from a professional mechanic. They can offer valuable insights into why your check engine light is activated and detail any repairs needed to pass the inspection.

3. Diagnostic Trouble Codes (DTCs)

Even with the check engine light lit, there may be instances in which the DTCs suggest a non-emission-related issue. In such cases, there is a slight possibility of passing inspection if it does not pertain directly to emissions systems. However, this scenario is infrequent, and it’s prudent to resolve any diagnostic codes promptly.
