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.
Is it safe to drive with P0792?
Usually safe to drive in the short term. Get it diagnosed when convenient, sooner if the car drives differently.
Common causes
- Most likelyAged Hall element with reduced amplitude
- Less likelySensor element aged beyond calibration window
- Less likelySensor mounting loose - signal damping
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
