Description

During crank, vBatt drops to 5v, which in turn drops one channel of TPS to a lower value, creating a large TPS drift, which in turn triggers P2135. Instead of resetting or allowing to recheck after voltage has been restored, ETB remains off, even if engine is now successfully running,

Am fine to add provision of checking if this error occurred during low voltage, and to auto reset upon engine running with vBatt restored to sensible values.
