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.
Affected components
- Intermediate shaft speed sensor a
Common causes
- High likelihood: Aged Hall element with reduced amplitude
- Low likelihood: Sensor element aged beyond calibration window
- Low likelihood: Sensor mounting loose - signal damping
Possible 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
Diagnostic notes
- The malfunction indicator lamp may illuminate
