2025 Toyota Grand Highlander Check Engine Light Codes

The 2025 Toyota Grand Highlander can log a range of OBD-II codes — from simple sensor faults (P0130-series oxygen sensor codes) to more serious issues like catalytic converter efficiency (P0420) or misfire codes (P0300-series). In Auburn, MA, Herb Chambers Toyota of Auburn is equipped to decode each code and explain the potential consequences: an unresolved oxygen sensor issue can reduce fuel economy and damage the catalytic converter, turning a relatively inexpensive sensor replacement into a costly exhaust repair; misfires left untreated accelerate wear on pistons and catalytic systems; and persistent fuel system codes can lead to stalling or poor drivability. Our certified Toyota technicians provide transparent estimates and prioritize repairs that save you money today and protect resale value tomorrow. We use OEM parts to ensure compatibility and longevity, and our service advisors will outline immediate and projected expenses so you can make an informed choice.
