Condition
DTC P0727 (Engine Speed Input Circuit No Signal, Sporadic) is stored in the transmission control module.
Technical Background
At engine start, the engine speed signal arrives to the TCM with delay. The entry is stored because the diagnosis is too sensitive. Drivability is not
affected by this condition.

Service
If the entry is sporadic or only sets on vehicle start, it can be deleted and ignored. A parts replacement will not address the condition, and the claim will
be denied.
