P2740: Transmission Fluid Temperature Sensor Circuit Low Input
The P2740 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 and sets the OBDII code when the signal is out of factory specifications.
The P2740 code specifically refers to the Transmission Fluid Temperature Sensor ‘B’ Circuit.
FAQ
If you see the engine light on or the service engine soon warning light, it could be due to the P2740 fault code. This code is usually caused by a faulty transmission fluid temperature sensor, an open or shorted sensor harness, or a poor electrical connection in the sensor circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector pins.
If you’re experiencing the P2740 fault code, which is indicated by the Engine Light ON or Service Engine Soon Warning Light, you may need to visually inspect the related wiring harness and connectors. This fault code is caused by a faulty Transmission Fluid Temperature Sensor, an open or shorted harness, or a poor electrical connection. To fix it, check the possible causes listed above and look for damaged components. Additionally, inspect the wiring harness and connectors for broken, bent, pushed out, or corroded pins.
Ignoring the P2740 fault code, which indicates a faulty transmission fluid temperature sensor or related wiring issues, can lead to serious consequences.
