Diagnostic boundary
A diagnostic trouble code reports that a monitored test failed. It does not prove one specific part is bad, and manufacturer logic can add vehicle-specific conditions.
Do not diagnose the transmission mechanically from P0702 alone; the electrical subcode or enhanced data usually points the way.
Useful checks before replacing parts
- Scan the transmission controller or enhanced data for companion solenoid, sensor, power, ground, or communication codes.
- Check transmission control fuses, relays, connectors, grounds, harness routing, and fluid intrusion at connectors.
- Review whether the transmission is in limp mode and what gear or command state was active in freeze-frame data.
