Can you still drive with P2C93?
✅Safe to drive — this is an informational or minor issue. Schedule diagnosis at your convenience.
Typical repair cost: $30 – $300
Severity Level 1 — Low
This code indicates a minor issue that is unlikely to cause immediate driveability problems. You can typically continue driving but should have the vehicle inspected at your earliest convenience.
Common Symptoms
- Power management behaving erratically or inconsistently
- Power management working sometimes, failing other times
- System performance degrades under specific conditions (temperature, load, etc.)
- Diagnostic trouble code (DTC) stored in module memory
Possible Causes
- Battery saver relay failing — output signal drifts outside expected range, common with age (80k-120k miles)
- Wiring or connector with intermittent high resistance — causes signal to fluctuate, especially with temperature or vibration
- Mechanical issue with the battery saver/power management system causing the sensor/actuator to operate outside its designed range
- Contamination or debris affecting battery saver relay operation — dirt, oil, or moisture interfering with readings
- Software/calibration issue in the control module — may need reprogramming rather than parts replacement
Common Fixes
- Scan vehicle with a professional-grade OBD2 scanner to read all stored codes and freeze frame data — note the conditions when the code set ($35-104 at shop, free at auto parts store for basic scan)
- Visually inspect the battery saver/power management system wiring harness and connectors — look for chafed wires, melted insulation, green corrosion, loose pins, or rodent damage (often free to check yourself, $129 diagnostic fee at shop)
- Replace battery saver relay — slow degradation over time is the most common cause of range/performance codes, especially on vehicles with 100k+ miles ($30-300)
- Check for vacuum leaks, exhaust leaks, or mechanical issues that could be causing the battery saver/power management system to see out-of-range conditions ($134 diagnostic smoke test + repair)
- Update control module software/firmware — some range/performance codes are fixed by a PCM reflash from the dealer ($109 at dealer)
