P0792: Intermediate Shaft Speed Sensor A Circuit Range/Performance
The intermediate shaft speed sensor (between input and output, used in CVT and dual-clutch boxes for slip detection between gear elements) is electrically intact, but its readings drift away from the model. The TCM cannot reliably detect slip in this stage.
What P0792 means
P0792 is a generic OBD-II powertrain code in the transmission group. In plain English: the signal is within electrical limits but doesn’t make sense compared with other readings, so the part or system isn’t performing as expected.

- Usually on
- Emissions-related
- No

Symptoms
- Check engine or transmission warning light on
- Harsh, delayed, or missing shifts
- Possible limp mode (locked in one gear)
- Slipping or shuddering during gear changes
Common causes
- 01Aged Hall element with reduced amplitudeMost likely
- 02Sensor element aged beyond calibration windowLess likely
- 03Sensor mounting loose - signal dampingLess likely
Can I drive with P0792?
Usually yes, for a short time.
The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
Why we rate it moderate
- Turns on the check engine light
Severity is our rule-based rating from the code’s flags in OBDex and the system it affects, not an inspection of your car. If the check engine light is flashing, or you notice overheating, low oil pressure, or brake or steering problems, stop driving and get help.
How to diagnose P0792
- 1
Confirm the code and save freeze-frame data
Read the codes with an OBD-II scan tool and note every code, not just P0792. Save the freeze-frame data (speed, load, temperature when the fault set) before clearing anything; it tells you when the fault happens.
- 2
Check for related codes first
Look for P2746, P2750. Related codes often share a cause; a circuit or sensor code usually needs fixing before a performance code like this one.
- 3
Test the circuit
Inspect the wiring and connector at the intermediate shaft speed sensor a for damage, corrosion or chafing. With a multimeter, check supply voltage, ground and signal against the specifications in the service manual for your vehicle.
- 4
Test the likely causes in order
Start with the most likely cause and work down: Aged Hall element with reduced amplitude; sensor element aged beyond calibration window; sensor mounting loose - signal damping. Test before replacing parts.
- 5
Check for recalls and service bulletins
Look up recalls for your exact vehicle with its VIN, and ask a dealer about technical service bulletins (TSBs). Manufacturers sometimes issue software updates or extended warranties for known faults.
- 6
Clear the code and verify the repair
After the repair, clear the code and drive the car under the conditions in the freeze-frame data to confirm it does not return.
P0792 repair cost estimate
Estimate, not a quote. Labor times are typical ranges for this code from OBDex, and $125/hr is an assumed rate. Shop rates and labor times vary by vehicle and region. Diagnosis time may be billed separately.

P0792 FAQ
What does P0792 mean?
P0792 means “Intermediate Shaft Speed Sensor A Circuit Range/Performance”. The intermediate shaft speed sensor (between input and output, used in CVT and dual-clutch boxes for slip detection between gear elements) is electrically intact, but its readings drift away from the model. The TCM cannot reliably detect slip in this stage.
Is P0792 serious? Can I keep driving?
We rate P0792 as moderate severity. Usually yes, for a short time. The car will often drive normally, but get it diagnosed soon. If you notice rough running, warning lights flashing, overheating or a burning smell, stop driving.
What causes P0792?
The most common causes, from most to least likely: Aged Hall element with reduced amplitude; Sensor element aged beyond calibration window; Sensor mounting loose - signal damping. Test before replacing parts, because several causes can set the same code.
How much does it cost to fix P0792?
Typical labor is about $75–$315 at an assumed $125/hour shop rate, plus parts. That is an estimate, not a quote: labor times and rates vary by vehicle and region, and diagnosis may be billed separately.
Can I fix P0792 myself?
DIY difficulty is moderate. Most owners leave this to a shop because it needs involved testing or specialist tools. Always confirm the cause before buying parts.
Will P0792 clear itself?
If the fault was intermittent, the warning may go off once the computer stops seeing it, but the code stays in memory. Fix the cause; clearing the code alone doesn’t repair anything.
