P2742: Transmission Fluid Temperature Sensor Circuit Low Input
The P2742 code is related to the Automatic Transmission Fluid (ATF) Temperature Sensor. This sensor converts the fluid temperature into a resistance value.
The Transmission Control Module (TCM) monitors the ATF Temperature Sensor signal. The code is set when the ATF Temperature Sensor signal is out of factory specifications.
The P2742 code specifically indicates that the ‘B’ circuit of the Transmission Fluid Temperature Sensor is reading low.
FAQ
