Results are grouped by useful content—not by paid placement or guessed parts. Describe the symptom naturally; IAR recognizes common alternate wording while keeping exact codes and vehicle details precise.

The control module detected cooling-system temperature behavior outside its expected performance range. The code does not by itself identify a thermostat, coolant-temperature sensor, fan, coolant level, radiator, water pump, or other failed part.
Generic codeThe control module reported a vehicle-speed-signal condition. The standardized code identifies the monitored speed-signal category; it does not prove which sensor, wheel-speed source, wiring path, module, or communication path is responsible.
Generic codeThe control module reported vehicle-speed-signal behavior outside its expected relationship. The standardized code identifies the monitored speed-signal category; it does not prove which sensor, wheel-speed source, wiring path, module, or communication path is responsible.
Generic codeThe control module detected a vehicle-speed-signal input below the range expected by its monitoring strategy. The generic code does not prove which sensor, wheel-speed source, wiring path, module, or communication path is responsible.
Generic codeThe control module detected intermittent, implausible, or high vehicle-speed-signal behavior. The generic code does not prove which sensor, wheel-speed source, wiring path, module, or communication path is responsible.
Generic codeIAR does not passively record this search. Save feedback only if you want a local note that you can export later for editorial planning. VIN-like vehicle identifiers are redacted before local save.
