P0708 - Transmission Range Sensor A Circuit High

Transmission range sensor A signal is higher than expected.

Treat the code as the starting point: compare symptoms, likely causes, and repair paths before pricing parts or moving into an estimate.

Code Overview

Transmission range sensor A signal is higher than expected.

Common Causes

• Transmission sensor, solenoid, or switch fault
• Damaged wiring or connector
• Internal transmission or control-module issue

Diagnostic Steps

1. Check transmission fluid condition and supporting codes
2. Inspect the related connector and harness
3. Compare commanded operation to live scan data if supported

Likely Repairs & Cost Guides

Use symptoms, scan data, and quick checks to confirm the likely repair path before pricing parts. The estimator helps compare repair paths before replacing anything unnecessarily.

Related OBD Codes

Browse nearby code-family pages when the same fault pattern overlaps across systems, such as misfire, lean fuel trim, EVAP sealing, cooling, or charging faults.

Next Steps

Move from code lookup to diagnosis, then estimate the likely repair only after symptoms, causes, and checks point to the same path.
