Clogged aftertreatment is the top cause of derates on Inland Empire box trucks, so we diagnose turbo, DPF, and DEF faults in our Yorba Linda shop off the 91. We clean and reinstall filters, test the DEF system, and coordinate turbo and internal aftertreatment overhauls through our vetted diesel partner network.

Note: We clean and diagnose aftertreatment in-shop and coordinate turbo and internal overhaul work through our vetted diesel partner network so your Corona fleet has one accountable point of contact.

## What this includes
- DPF removal, bake-and-flow cleaning, and back-pressure verification
- DEF quality, dosing, and pump testing to clear SCR and NOx faults
- Turbo actuator, VGT, and boost-leak diagnosis under live data
- Regen system and soot-load diagnosis to stop repeat derates
- NOx sensor, DPF pressure sensor, and temperature sensor replacement
- Coordinated turbo replacement and internal aftertreatment overhaul through our diesel partner network
- Fleet scheduling so Corona trucks clear derate limits and get back on route

## Who it is for
- Corona fleets stuck in derate or limp mode from a plugged DPF or DEF fault
- Operators seeing frequent regens and lost fuel economy on Inland Empire routes
- Fleets that want in-shop cleaning and diagnosis with turbo overhauls coordinated through partners

## Pricing
DPF cleaning and sensor work sit near the low end; turbo overhauls are coordinated through our partner network. Diagnostics billed at $285/hr.

## FAQ
### Can you clean my DPF instead of replacing it?
In most cases yes. We bake-and-flow clean the DPF and verify back pressure so Corona operators avoid the cost of a new filter when cleaning restores flow.

### Why does my truck keep going into derate?
Repeat derates usually trace to a plugged DPF, bad DEF quality, or a failing NOx sensor. We read live aftertreatment data to find the real cause for Inland Empire fleets.

### Do you rebuild turbos in-house?
We diagnose the turbo and remove it in our shop, then coordinate the overhaul or replacement through our vetted diesel partner network so your Corona truck has one point of contact.
