P0181 Fuel Temperature Sensor A Circuit Range / Performance
The fuel temperature sensor A signal is within electrical limits but inconsistent with plausibility checks (e.g. doesn't change with engine warmup, disagrees with ambient temperature).
Is it safe to drive with P0181?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
