The intermediate shaft speed sensor measures a shaft between input and output – a countershaft on Toyota's U760 six-speed, the intermediate shaft behind the overdrive set on Ford's 5R110W. Together with turbine and output speed it lets the module check each gear stage and control clutch slip. P0792 means a signal is present but implausible: intermediate shaft speed does not match turbine or output speed for the detected gear stage, exceeds a maximum or jumps unrealistically. No manufacturer document available to us uses this code – Ford uses only P0791, Toyota's bulletin P0791/P0793, GM its own codes; the logic follows GM's range checks for input and output sensors (P0716/P0721). Ratio codes, by contrast, point to clutch slip rather than a sensor fault.
Medium severity. Can I keep driving?Drive gently to a repair shop. If it slips, you hear clunks, or it loses its gears, do not keep driving.
Symptoms
- Check engine light or transmission warning
- Shift problems
- Limp mode possible
Most likely causes
- Sensor delivering faulty pulses (air gap, reluctor wheel)
- Interference or loose contact
- Mechanical slip interpreted as a sensor fault
- Wrong sensor fitted
What to check, in order
Start with the simplest. You can tick off each step.
Good to know
- Repair difficulty: medium
- It can trigger limp mode.
- It affects emissions.
What each character of P0792 means
- P: Powertrain: engine and transmission
- 0: Generic code: same on every make
- 7: Transmission
- 92: Specific fault in that system
