2025 Toyota GR Supra 3.0 Check Engine Light Codes

Common check engine light codes for the 2025 Toyota GR Supra 3.0 include oxygen sensor (O2) codes, misfire (P0300–P0306) codes, and turbo or boost-related sensor faults. Each has cost and consequence implications: an O2 sensor left unaddressed may degrade fuel economy and damage emissions components; a misfire that continues can ruin catalytic converters and lead to far higher repair bills; boost sensor or intercooler leaks reduce performance and accelerate wear. At Herb Chambers Toyota of Boston we identify codes quickly using OEM tools and explain both the repair path and the cost-benefit analysis—showing how timely service saves fuel, preserves horsepower (notably the Supra’s 382 hp output), and protects resale value. Our Boston location offers efficient bays, genuine Toyota parts, express check-in, and technicians certified on Toyota performance engines, so diagnostics and repairs are fast and reliable.
