Code P1164 Volkswagen Description
The P1164 diagnostic trouble code (DTC) for Volkswagen vehicles indicates a problem with the Fuel Temperature Sensor (FTS) sending an implausible signal to the engine control module (ECM). The FTS is a crucial component that measures the temperature of the fuel in the vehicle's fuel tank. This information is used by the ECM to adjust the air-fuel mixture for optimal combustion efficiency. When the ECM receives an implausible signal from the FTS, it can lead to poor engine performance, reduced fuel efficiency, and potential long-term damage if left unresolved.
