What P0792 means
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.
P0792 at a glance
- Check engine lightYes, usually on
- Emissions testCan fail
- Limp modePossible
- Repair difficultyMedium
- Typical labor1.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P0792
- Check engine light or transmission warning
- Shift problems
- Limp mode possible
Common causes of P0792
- Most likelySensor delivering faulty pulses (air gap, reluctor wheel)
- PossibleInterference or loose contact
- Less likelyMechanical slip interpreted as a sensor fault
- Less likelyWrong sensor fitted
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P0792 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 0 | Generic code: it means the same on every make (SAE standard). |
| 7 | Area: transmission. |
| 92 | The exact fault in that area. |
What to do next
- Note P0792 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P0792
What does P0792 mean?
P0792 means "Intermediate Shaft Speed Sensor A Circuit Range/Performance". 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. It is a generic code, so it means the same on every make.
Is it safe to drive with P0792?
Drive gently and only to a workshop. With P0792 the car can go into limp mode (reduced power) to protect itself.
Will P0792 fail an emissions test?
Yes, it can. P0792 is emissions-related, so most inspection programs fail a car while it is stored or while the check engine light is on.
How hard is P0792 to fix?
Difficulty: medium. A typical repair takes 1.5 to 3 hours of work. This is a job for a workshop.
Will P0792 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
