Frequently asked questions
Can you fix an exhaust leak before it damages my aftertreatment?
Yes. Leaks ahead of the DPF skew sensor readings and trigger faults, so we seal manifolds and pipes to protect Corona trucks from costly downstream aftertreatment damage.
Do you handle EGR problems?
We clean or replace EGR valves and coolers and check for coolant intrusion, a common cause of rough running and check-engine lights on Inland Empire diesels.
Will my truck pass California emissions after service?
We repair the cause of emissions faults and verify no active codes remain, giving Corona operators a truck that runs clean and meets California standards.
