Jean-Eric Vergne has been given a 10-place grid penalty for an unsafe release in FP2, while Toro Rosso has been given a €30,000 fine.
The Frenchman lost a rear wheel immediately after leaving the pits towards the end of FP2 after what had been a relatively leisurely pit stop of around 8s.
The FIA said: “This is regarded as a serious offence and the stewards are of the opnion that this was a significant breach of the safety requirements.”
The team will also have to prove that it is compliant with Article 14.7 of the technical regulations, which reads: “All cars, whilst under their own power, must be fitted with devices which will retain the wheel fastener in the event of it coming loose.”
The team believes that the wheel was not properly located, and thus nor was the retention device, which thus failed to deploy.
The stewards also asked the FIA technical delegate to check that all other cars are also compliant.
