P1182 Fuel Temperature Sensor Low Input
What does P1182 mean on a Honda?
P1182 — Fuel Temperature Sensor Low Input. This Honda-enhanced code applies to Civic, Accord, CR-V with returnless fuel systems.
Common causes of P1182
- Fuel temperature sensor signal wire shorted to ground
- Failed fuel temperature sensor reading stuck low
- Corroded fuel pump module connector wicking fuel vapor
- Pinched harness under the rear seat or fuel tank
- Failing ECM sensor ground circuit
How to fix P1182
- Compare the fuel temperature PID against ambient on a cold soak with a scan tool
- Inspect the fuel pump module connector for corrosion and pin damage
- Test the signal wire for a short to ground between the tank and the ECM
- Check the sensor resistance against the temperature chart in the service manual
- Replace the fuel temperature sensor after wiring proof, then verify the PID tracks ambient
