Diesel Motorhome CARB Testing in San Diego
San Diego RV Center provides CARB compliance testing for diesel motorhomes in San Diego. Our credentialed technicians perform OBD-based Clean Truck Check inspections to keep your diesel RV compliant with California Air Resources Board regulations.
As of January 2025, all heavy-duty diesel vehicles — including motorhomes and RVs with a Gross Vehicle Weight Rating (GVWR) over 14,000 pounds — must pass emissions testing and submit results to the California CARB database. Without a passing inspection, your vehicle may be flagged with a DMV registration hold at renewal.
We handle the entire process so you can get back on the road. We test your diesel motorhome, submit your results directly to CARB, and make sure your vehicle clears compliance before your next registration cycle.
Our RV CARB services include:
- OBD diesel emissions testing
- CARB compliance certificates
- Direct results submission to the CARB database
- Clean Truck Check (HD I/M) inspections
While you’re here, consider an oil change or annual maintenance.
Conveniently located off Interstate 8 in El Cajon, we serve RV owners across San Diego, El Cajon, La Mesa, Santee, Lakeside, Spring Valley, and Lemon Grove.

Diesel RV CARB Testing FAQs
Does my diesel motorhome need CARB testing?
If your diesel RV has a GVWR over 14,000 pounds, then yes — as of January 2025 California requires periodic Clean Truck Check emissions testing with results submitted to the CARB database.
What happens if I don’t pass CARB compliance?
Your vehicle can be flagged with a DMV registration hold, which prevents you from renewing your registration until you pass and your results are submitted.
How does the Clean Truck Check test work?
For most newer diesel RVs it’s an OBD-based inspection. Our credentialed technicians run the test, then submit your results directly to CARB so you’re cleared for registration.
How often do I need CARB testing?
Heavy-duty diesel vehicles are subject to periodic testing tied to your registration cycle. We’ll confirm your schedule and keep you compliant.
Do you submit the results to CARB for me?
Yes. We handle the entire process, including submitting your passing results directly to the CARB database before your next registration cycle.
