Can a speed sensor cause a transmission to slip?
Without accurate information from the vehicle speed sensors, the transmission torque converter will be unable to apply the clutch and form a mechanical link between the engine and transmission. This can cause slipping, reduced fuel economy, and an overheated transmission.
How do I know if my transmission speed sensor is bad?
- Transmission revs higher before it changes gears.
- The car’s transmission engages into overdrive late and sometimes will never go into that top gear.
- Brakes are sometimes harder than normal when coasting.
- Speedometer behaves erratically or sometimes does not work at all.

Why does my Toyota cel say p0793?
After replacement and 10min of driving, the same issue is occurring, CEL came back on and now calls P0793 and P2714. The hard shifting actually got worse after the new sensor (occurring in more of the gear changes). For future readers. I solved the problem by changing out the NC speed sensor with a toyota speed sensor I got from the dealer.
When does the p0793 sensor detect engine speed?
The P0793 code is detected when the vehicle speed is more than the 31 mph and the park/neutral switch is OFF or rhe engine speed is less that 300 RPM. This sensor detects the rotation speed of the input turbine.
What is the speed sensor on a Toyota Sienna?
I have a similar transmission and CEL issue on a 2008 Sienna with 120K miles. It started shifting hard (mostly upshift between 1 and 2) and the CEL light came on with P0793 as the code. I replaced the “NC” speed sensor (top of the transmission) with an aftermarket sensor.
