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.
- Check engine light: Yes
- Emissions related: No
- Repair difficulty: medium
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
Ordered by how often each turns out to be the cause.
- Aged Hall element with reduced amplitudeCommon
- Sensor element aged beyond calibration windowLess likely
- Sensor mounting loose - signal dampingLess likely
