P1392 G-Sensor Voltage Low
What does P1392 mean on a Honda?
P1392 — G-Sensor Voltage Low. This Honda-enhanced code applies to CR-V, Odyssey, Accord with rough-road G-sensors.
Common causes of P1392
- Failed rough-road G-sensor stuck at low voltage
- G-sensor signal wire shorted to ground
- Corroded G-sensor connector under the center console or floor
- Poor G-sensor ground raising the voltage drop
- Failing ECM sensor input circuit
How to fix P1392
- Read the G-sensor voltage PID with a Honda HDS scan tool over a bumpy road test
- Inspect the G-sensor mounting, it must be torqued flat to read correctly
- Backprobe the sensor for reference voltage, ground, and signal
- Test the signal wire for a short to ground
- Replace the G-sensor after wiring proof, then verify voltage varies with road input
